AB - There has been increasing evidence in recent years about the impact of soil structure on vadose zone hydrology and the distribution of surface applied chemical substances. We have carried out a combined dye and radionuclide tracer study on two monoliths from the same location, one structured and one repacked, as part of an ongoing study to investigate the link between preferential flow, leaching of surface applied substances and their distribution within the soil. A tracer solution containing 1300 Bq/L (super 58) Co and 0.31 mu mol/L Sulforhodamine B (SB) was added with roughly constant irrigation during a period of three weeks. The dye served as a tracer for water movement within the soil and thus allowed linkage of the radiotracer ( (super 58) Co) with the flow pattern. Both were monitored in the outflow and measured within profile sections after monolith disassembly. Preferential flow in the structured monolith promoted the bypass and transport of both tracers, although transport was impeded at depths greater than 30 cm by compacted soil and reduced hydraulic conductivity. Eighty four percent of radiocobalt and 8% of SB were found in the upper 4 cm of the structured monolith. The homogenized monolith, on the other hand, showed mostly chromatographic infiltration and a more efficient soil filtering capacity with 91% of radiocobalt and 20% SB residing in the upper 4 cm. Furthermore no tracer was found in the outflow of the homogenized monolith during normal to high irrigation or at greater depth within the monolith. We have related flow characteristics and sorption of radiotracers by quantifying dye distributions and radionuclide activities throughout the profiles. Activities within the flow paths are up to 20-times higher than those measured in the soil matrix, and a fraction of radiocobalt follows the dye tracer in spite of cobalt's low mobility. The dye can thus be used to trace radionuclide distribution within the soil block. AD - ETH Zuerich, Institute of Plant Sciences, Experimental Station Eschikon, Lindau, Switzerland AU - Albrecht, A.

Much of Shade's fieldwork was conducted on public land in Banning State Park, Department of Natural Resources Forest Land and Askov City Property. Askov has been under a moratorium on new sewer hook-ups for several years because of limited capacity in their 40 year-old Waste Water Treatment Facility lagoon. Effluent that periodically discharges from the lagoons sinks into "The Big Sinkhole" lake about one kilometer down stream. Several sinkholes exist immediately adjacent to the lagoons. These conditions are helping Askov's ongoing efforts to secure public funding for a new WWTF. The local karst hydrogeology limited the options available for additional sewage treatment but the added risk of groundwater contamination to local water supply wells has significantly increased Askov's priority and visibility for public funding. As part of a receptor survey of private wells near the Askov WWTF, two fluorescent dye traces were initiated on 23 April 2004. Rhodamine WT was added to the approved discharge of lagoon effluent to the adjacent sinking stream and fluorescein was injected into a sinkhole immediately west of the lagoon. RhWT was first detected in a private well about a mile southwest from the terminal sinkhole lake three weeks later. As of this writing, RhWT is still present in that well, has been confirmed in a second private well, and has been detected two more wells. The fluorescein was detected in less than three days in three monitoring wells installed northeast of the sinkhole through the lagoon dikes and is still strongly present in two monitoring wells. In late May the fluorescein was confirmed in a private well between the lagoon and sinkhole lake, west of the sinkhole, and has been detected in two additional private wells. The implied groundwater flow velocities and dispersion patterns are much faster and completely incompatible with porous media models but are slower than would be expected from highly integrated conduit flow.

Its surface was elaborated by the quaternary glaciers and includes some inherited discreet tertiary morphological features. Recent dye tracing has shown that the structural setting permits water infiltrated in Italian catchments to contribute to Slovene springs. Hydrodynamic and physico-chemical water analyses show extremely quick transfers of water during snow melt or heavy storms; these create spectacular overflows, such as the Boka spring which emerges as a 100 m high waterfall. The phreatic zone, linked to the impermeable dam of the Soca valley, does not significantly slow these transfers. Nevertheless, it contributes to the occurrence of low water levels during recession periods, giving highly mineralised water after long resident periods. The presence of very deep and developed karst systems is explained by the combination of advantageous factors: thick and jointed limestone, important height gradient, and considerable precipitation. Paleomagnetic dating in one of the largest systems (Crnelsko brezno) attributes some glacial sediments to the Lower Pleistocene period. Their configuration seems to show that this karst system is pre-Quarternary.

The Chocholowskie Vaucluse Spring is recharged mainly by karst systems, including that of the Szczelina Chocholowska-Jaskinia Rybia caves. The remaining 20% of water in the system comes from surface waters of the Chocholowski Stream. First successful dye tests were conducted on this system in 1971/1972. The paper presents data and interpretation of the recent dye-tracer experiments for the Chocholowskie Vaucluse Spring recharge area. The results of these tests prove that the connection between the Szczelina Chocholowska-Rybia caves karst system and the Chocholowskie Vaucluse Spring is of a karst-fissure character. This hydraulic connection is a typical example of a sub-channel circulation, where flow through a karst-fissure system takes place beneath the bottom of an existing river channel. Comparing the time of dye flow through the system with water stages indicates that the system of fissures linking the sinkhole zone with the vaucluse spring is at least three fold. The inverse relation between watermark stands reflecting the degree of watering in the massif and the time, at which dye penetrates the system, is also distinctly visible.

The column leaching studies used undisturbed core material obtained from the field by dry percussion drilling. Each column leaching study used 25 cm long, 10 cm wide unsaturated chalk cores through which a pulse of isoproturon and bromide was eluted. The cores were set-up to simulate conditions in the unsaturated zone of the UK Chalk aquifer by applying a suction of 1 kPa (0.1 m H (sub 2) O) to the base of each column, and eluting at a rate corresponding to an average recharge rate through the unsaturated Chalk. A dye tracer indicated that the flow was through the matrix under these conditions. The results from the first column study showed high recovery rates for both isoproturon (73-92%) and bromide (93-96%), and that isoproturon was retarded by a factor of about 1.23 relative to bromide. In the second column study, two of the four columns were eluted with non-sterile groundwater in place of the sterile groundwater used on all other columns, and this study showed high recovery rates for bromide (85-92%) and lower recovery rates for isoproturon (66-79%--sterile groundwater, 48-61%--non-sterile groundwater). The enhanced degradation in the columns eluted with non-sterile groundwater indicated that groundwater microorganisms had increased the degradation rate within these columns. Overall, the reduced isoproturon recovery in the second column study was attributed to increased microbial degradation as a result of the longer study duration (162 vs. 105 days). The breakthrough curves (BTCs) for bromide had a characteristic convection-dispersion shape and were accurately simulated with the minimum of calibration using a simple convection-dispersion model (LEACHP). However, the isoproturon BTCs had an unusual shape and could not be accurately simulated. AD - Institute of Hydrology, Wallingford, United Kingdom AU - Besien, T. J.

The system utilized conventional high-performance liquid chromatography instrumentation. We determined the diffusion coefficients for alkali halides and the dye tracers uranine (fluorescein) and Brilliant Blue FCF (FD&C blue #1). We also made the first experimental determinations of the diffusion coefficients of 16 fluorobenzoates (FBAs), and 2 chlorobenzoates (CBAs) in water, and in 0.1 M potassium phosphate buffer at pH 7.0. The measured diffusion coefficients for halide salts were within 5% of literature values. The diffusion coefficients of the dye tracers ranged from 5.68 to 6.48X10 (super -10) m (super 2) s (super -1) , depending upon concentration. The diffusion coefficients of the benzoates ranged from 8.5 to 9.8X10 (super -10) m (super 2) s (super -1) in water, and from 7.4 to 9.8X10 (super -10) m (super 2) s (super -1) in buffer. The diffusion coefficients of the FBAs and CBAs in water were 17% greater on average than calculated from their molecular structures. Diffusion coefficient differences among benzoate isomers could be only partially explained by molecular geometry. We will discuss questions related to measurement of diffusion coefficients in complex matrices, the appropriateness of using a single diffusion coefficient when tracer concentration varies in time and space, and the required accuracy of diffusion coefficients for different applications.

In recent years, there have been great advances made in the ability to characterize the hydraulic properties of fractures in bedrock wells. This information is vital to the ability to evaluate ground water supplies, wellhead protection, and in the prevention and remediation of ground water contamination in fractured crystalline rock. Although the United States Geological Survey (USGS) has developed state-of-the-art downhole techniques to characterize fracture properties, these methods may be cost prohibitive to be applied on a large scale and for use in the private sector. This investigation was undertaken to develop a cost-effective method of downhole fracture characterization using a tracer. This method will be able to identify water-bearing fractures that intersect the well, provide information on whether fractures are incoming (producing) or outgoing (receiving) under ambient conditions, determine the transmissivity and hydraulic head of those water-bearing fractures, and quantify fracture water quality. The field research for this study was conducted in three fractured bedrock wells located at the Branch of Geophysics of the USGS, at the University of Connecticut in Storrs, Connecticut. The tracer (uranine dye) was injected into the well, while at the same time water is pumped out of the well. After steady-state conditions are reached, a tracer concentration profile was developed for the well. Using the dilution of the tracer to determine the flow from a fracture, this flow rate, plus the drawdown in the well, can then be used to determine the transmissivity of that fracture by applying equations for a constant head flow test. The results of this investigation were then compared with the results from the USGS for the same three wells using their methods. This provided a unique opportunity to evaluate the tracer test results with those derived by the USGS methods.

Walker, PE, BCEE, Deputy Executive Director, Utility Operations Division, Florida Keys Aqueduct Authority, and Andrew Smyth CH2M Hill ID - 380 ER - TY - JOUR AB - Continual horizontal flow of formation water through a monitoring well screen is commonly cited as a basis for interval sampling using low-flow or no-purge sampling techniques. A few studies have shown horizontal flow for short periods of time, and others have demonstrated specific circumstances under which the assumption fails. But, surprisingly, this investigator could not find direct testing of the underlying concept-that under "normal" conditions (i.e., no vertical hydraulic gradient) water enters one side of a well and exits the other side of the well at roughly the same elevation. To test the horizontal flow assumption, a physical sand tank model was constructed to observe flow-through in a simulated monitoring well. The well, filter pack, and aquifer on either side of the well largely mimics real-world conditions of a submerged well in a moderately high permeability sand. Behavior of a dye "stringer" was recorded using digital time-lapse photography at real-world ground water seepage velocities. Neutrally-buoyant and different-density dye "stringers" were observed entering the well over a period of several days for each test. In all tests, regardless of flow rate or small density differences, the dye stringer eventually diluted and mixed in the monitoring well. Since the well model closely approximates a cross-section of an actual-size well subjected to real-world flow rates, mixing appears to be the rule rather than the exception for near-neutrally-buoyant contaminant stringers as they enter monitoring wells. There are several clear and important implications. 1) In-well mixing and flow-weighted concentration averaging occurs in a well before any purge or sampling efforts are made. 2) In-well mixing may mask low to moderate contaminant stratification in an aquifer. 3) Contaminant stratification, if present inside a well, implies strong contaminant stratification outside the well. 4) Contaminant stratification inside a well may not correspond to stratification at the same interval outside the well. 5) Vertical stratification within an aquifer may not be accurately monitored by sampling multiple intervals within an open well. 6) In-well barriers may limit mixing and assist in defining intervals of aquifer contaminant stratification.

Comparison between experimental and computed data leads to conclusions about the validity of the method.

The onset of wetting front instability and the characteristics of the flow pattern under nonponding infiltration have received limited attention. We aim to theoretically and experimentally advance our understanding of pre-fingered flow, and contrast fingered flow under ponding and nonponding conditions. We developed a Green-Ampt based expression for the pressure head in a developing induction zone (from which fingers protrude) for the time before fingers developed. A uniform, nonponding water flux was applied to the surface of two-dimensional glass bead porous media with a dry region above a capillary fringe. Microtensiometers recorded pressure heads in the induction zone. The pressure head data confirmed both the theoretical early-time pre-finger model, and a model developed earlier for late-time lateral flow toward fully developed fingers. The physically more realistic constant flux boundary condition of our experiments gave larger finger spacings and travel times, compared to the frequently used set-up with ponding infiltration into a fine-over-coarse porous medium.

The karst aquifer underlying Fort Knox is developed within approximately 60 m of the St. Louis Limestone and is bounded on three sides by surface streams that represent the local base level. The underlying Salem Limestone acts as a regional aquitard and provides a lower limit to karst aquifer development. The study area covers over 130 km (super 2) and contains over 200-inventoried karst features. As a part of this investigation, innovative multiple dye trace events were conducted throughout the study area using up to six dyes per event with a total of eight dyes used to conduct 14 dye traces during three seasonal events. Dye trace results, structural and topographic controls, spring characteristics, and normalized base flow were used to establish groundwater basin limits and boundary zones and to develop a conceptual sitewide groundwater flow model. The primary finding of this work indicates sitewide groundwater flow is controlled directly or indirectly by local stratigraphy, geologic structure, and changes in stream levels in the geologic past, and that two groundwater basins dominate the study area, accounting for approximately 80% of measured sitewide groundwater discharge. The findings of this investigation will be used to assess the groundwater contaminant contribution from source areas in individual basins, develop an effective groundwater monitoring program, and guide future groundwater management strategies.

However the determination of the discharge from the resulting experimental curves is not immediate. Using a same scale mock-up, a parametric study was conducted for a range of dilution discharges close to that found under field conditions. A physical conceptualization of the system is proposed, i.e. an arrangement of simple flow models, such as plug flow and a perfectly agitated tank. The mass balance law applied to this arrangement leads to a system of equations that is solved in the Laplace domain. An analytical solution is obtained, and two fitting methods with respectively two and four unknowns are examined.

Tracer and water-quality samples were collected at multiple river and hyporheic sites as well as at the Los Angeles County Sanitation Districts Saugus and Valencia Water Reclamation Plants. These water reclamation plants provide the main source of base flow in the river. Rhodamine WT dye was injected into the river to determine river traveltimes and to indicate when Lagrangian water-quality sampling could be performed at each site. Sodium bromide was injected into the river at a constant rate at the water reclamation plants to evaluate the surface-water and shallow ground-water interactions in the hyporheic zone. AD - U. S.

This paper discusses dye traces that confirmed that the Barren River and Drakes Creek in south-central Kentucky are losing water as part of these streams sink into the limestone and flow across large meanders to resurge at springs downstream. Other examples in west Kentucky and Tennessee will be discussed. Case studies will be presented where a dam was almost constructed at a location on a stream where a subsurface meander neck cut-off would have probably prevented the impoundment of water behind the dam, and at another site where microgravity and dye traces were used to assess the potential for subsurface meander neck cut-offs at a proposed dam site. A third case study will deal with dye traces recently performed to investigate the source of a large boil discharging about 15,000 cfs located about 1800 feet downstream from Jim Woodruff Dam in Florida. Dyes were injected into holes in the bed of Lake Seminole, located by a multi-beam hydrographic survey, about 1500 feet upstream from the dam and traced under a leaky confining layer through the Floridan Aquifer to the boil.

Polk Lake Spring is located about 244 meters (800 feet) downstream, and a large boil, estimated to be 424,753 liters per second (15,000 cfs), created by water rising from a hole in the river bed, is located in the Apalachicola River about 549 meters (1,800 feet) downstream. This research was initiated by the Mobile District US Army Corps of Engineers to determine if water from the spring and/or boil is leakage from the reservoir, groundwater, or both. EMC, Inc. performed a multi-beam hydrographic survey of the lake bottom topography, identifying five potential leakage sites. The most distant hole identified by the lake bed survey was approximately 434 meters (1,425 feet) upstream from the dam. A dye tracer investigation was conducted to determine if any of these sites was contributing to the discharge at the spring and/or boil located downstream from the dam. After a karst hydrogeologic inventory was conducted, activated charcoal dye receptors were placed at twelve locations, and ISCO automatic water samplers at three locations. Three fluorescent dyes were used for the tracer tests. The investigation indicates that lake water sinking into holes in the lake bed is flowing through old solution conduits in the limestone bedrock that existed previous to dam construction. All the leakage confirmed by dye tracing is resurging at the boil located in the river downstream from the dam. However, most of the leakage first resurges at Polk Lake Spring and then sinks at Polk Lake Sink to finally resurge at the boil. Jim Woodruff Dam was built upon the lower Tampa Limestone, a semi-confining unit for the Upper Floridan Aquifer. The geologic dip in the vicinity is downstream perpendicular to the dam. The Suwannee Limestone, the uppermost geologic unit of the Upper Floridan Aquifer, outcrops under Lake Seminole but dips below the Tampa semi-confining unit in the vicinity of the dam. Additional leakage may be sinking through reactivated sinkholes in the lake where the Tampa semi-confining layer is thin. This leakage may then flow through the Suwannee Limestone (Upper Floridan Aquifer) down dip to resurge at the boil located about 549 meters (1,800 feet) downstream from the dam, where the Tampa is thin due to the downcutting of the Apalachicola River Valley.

Hydrographs for observation wells into large cave streams show that during major flood-producing rains the stage can rise over 30 m (100 ft) while water wells located 183 m (600 ft) distant indicate that the hydrograph crest lags several hours behind that of the main conduit and only rises approximately 2/3 as high in elevation. This evidence supports the hypothesis that storm water from large cave streams flows back into karst aquifers and is analogous to river bank storage in alluvial aquifers. During heavy rains, surface runoff flowing rapidly into cave streams from sinking streams and open-throat sinkholes carries more suspended sediment and other non-point source contaminants than water percolating through the soil. The flow of storm water from cave streams back into the aquifer appears to be one reason why some farmers' water wells often become muddy during and after heavy rains. Also, an increase in non-point source contaminants occurs in water wells similar to that of karst springs during and after heavy rains. Water samples collected from cave streams and springs during and after storm events also show an increase in point source contaminants. Rather than a decrease in point source contaminants due to dilution, data show an actual increase in concentration of several different contaminants from a known contaminated site during and after storm events compared to their concentrations during base flow. This clearly indicates the need for storm event monitoring in free-flow karst aquifers. Finally, the paper discusses an investigation to determine the best time for sampling at a spring during the rise and fall of a storm hydrograph for point source contaminants. This study involved tagging groundwater flow from a contaminated site to a spring by injecting three different fluorescent dyes. One dye was injected into a sinking stream, a second dye into a sinkhole and a third dye into the soil at the beginning of several heavy rains. Dye breakthrough curves were then monitored at the contaminated spring. Recommendations concerning when and how often to collect samples at springs during the rise and fall of storm hydrographs are presented.

The mantle karst located in Northwest Arkansas makes it almost impossible to model groundwater flow accurately. Dye studies in the area show that simple topography will not always predict groundwater movement and groundwater basins do not coincide with surface watersheds.

The ability to forecast advective transport of a contaminant. All known water users can be provided with advance warning using this forecast. Because the data set was developed from information collected for other purposes, it may not include all potential impacted sites. However, houses and other structures could also be identified using the GeoTIFF images to insure complete notification. It is important to note that this data set much like any data set used in GIS analyses is dynamic and is continuously being updated with new information.

Although it is generally believed that movement of pathogens through the soil is minimal, recent research has shown that appreciable numbers of C. parvum oocysts may be transported via preferential or fingered flow to groundwater. The objective of the present research was to further investigate and model the transport of oocysts through preferential flow paths in the vadose zone under a "worst-case" scenario. This was studied by adding calves feces containing C. parvum oocysts with a Cl- tracer to undisturbed silt loam columns and disturbed sand columns during a simulated steady-state rain. The sand columns exhibited preferential flow in the form of fingers whereas macropore flow occurred in the undisturbed cores. In the columns with fingered flow, oocysts and Cl were transported rapidly with the same velocity through the columns. Although only 14 to 86% of the amount applied, the number of oocysts transported across the columns was several orders of magnitude above an infective dose. The macropore columns had only a very limited breakthrough of oocysts, which appeared several pore volumes after the Cl broke through initially. A simulation model for the transport of oocysts via preferential flow was developed on the basis of an existing preferential flow model for nonadsorbing solutes, with addition of a first-order sink term for adsorbance of the C. parvum to the air-water-solid (AWS) interfaces, and with velocity and dispersivity parameters derived from Cl (super -) transport. The breakthrough of C. parvum oocysts could be described realistically for the sand columns. However, the model could not describe oocyst transport in the columns with macropores.

Buchholz) and karst geology on the regional water cycle in the Edwards plateau region of Texas are complex and not well understood. The objective of our study was to gain a comprehensive understanding of the subsurface flow processes occurring at a juniper woodland site on the Edwards Plateau near Honey Creek State Natural Area. A 2.3-m-deep, 7-m-long trench was excavated at the downslope end of a 7 by 14 m experimental plot, and time domain reflectometry (TDR) probes were installed at various locations within the trench face to measure volumetric water contents. A multi-port telescopic boom type rainfall simulator was used to provide artificial rainfall on the plot. Six rainfall simulations and two dye-tracer tests were conducted on the plot during a 7-mo period. Subsurface flow was visually inspected at various locations on the trench face during artificial rainfall experiments and water content was monitored near slow and fast flow regions using TDR probes. The total volume of subsurface flow was also recorded after each rainfall simulation event. Results demonstrated that subsurface flow occurred in a bimodal manner, consisting of preferential/macropore flow around juniper root channels and planar fractures in the limestone, and pseudo-matrix flow through the soil matrix (water flowing primarily through the intermediate layers and lenses of soil between the rock layers). Preferential/macropore flow at the trench face depended on imposed boundary conditions and was independent of antecedent moisture content in the soil matrix. Pseudo-matrix flow response time decreased with high rainfall. During large rainfall events (>200 mm), water exchange was observed between the fractures and soil matrix. No apparent water exchange occurred between fractures and the soil matrix during small rainfall events. The dye studies indicated that fractures and juniper root channels are primary pathways for preferential/macropore flow occurring within the plot.

A2 - Stefanic, Jenelle M. AB - The Leadville Mine Drainage Tunnel (LMDT) is a 3.3 kilometer structure that was constructed in the complicated geology of the Leadville mine district in the 1940's. Discharge from the LMDT is impacted by heavy metals and is treated at a plant built in 1992 operated by the United States Bureau of Reclamation. On the surface waste rock and other remnants of the mining operations litter the landscape and this material is exposed to precipitation. As a result of contact with this material, surface water often has pH of less than 3 and its containment and disposal is necessary before it impacts surface drainage and the nearby Arkansas River. Using a borehole drilled into the mine workings the U.S. EPA has devised a plan in which the impacted water is contained on the surface which then can be discharged into the mine workings to discharge from the LMDT and be treated. The percentage of water discharging from the mining district along the drainage tunnel is unknown, and since there is no access, information about the condition of the tunnel with regards to blockages is also relatively obscure. Application of quantitative water tracing using fluorescent dyes was used to model the flow parameters at the scale of hours in the tunnel and evaluate the likelihood of blockages. Because the tunnel has intersected several lithologies and faults, other locations such as discharging shafts, adits and surface streams that could be hydraulically connected to the LMDT were also monitored. An initial tracer experiment was done using an instantaneous injection, which was followed by additional injections of water. Another tracer injection was done when there was a continuous flow of impacted water into the workings. Analysis of the tracer concentration responses at water-filled shafts and at the portal were used to model the flow along the tunnel and estimate several hydraulic parameters. Waters in these settings are mixtures of components with different residence times, so, qualitative tritium data were used to evaluate residence times of decades.

The contribution zone for this system extends from north of Tallahassee to the Spring Creek springs on the Gulf Coast. This type of aquifer is best characterized as a dual or triple porosity system consisting of matrix, conduits, and possibly fractures. In such systems, groundwater velocities can span more than 30 orders of magnitude; more than 97% of the flow is typically through the conduits; and more than 95% of the storage is in the matrix. Groundwater protection efforts in north Florida are focusing on groundwater modeling as a means of delineating vulnerability zones however these efforts are met with significant challenges because of the dual porosity nature of the aquifer. To help address this problem, artificial tracers were used to calculate groundwater velocities in the conduits over distances of approximately 300 and 2600 m. Both traces revealed groundwater velocities of between 0.02 and 0.03 m/s, Reynolds Numbers of 105, and nearly identical standardized breakthrough curves. When compared to natural tracer data such as from CFCs, tritium, or tritium/helium-3, which have revealed groundwater ages on the order of decades, these data indicate that the groundwater ages must be a composite of very old water from the aquifer matrix and very young water from the dissolved conduits. Effective groundwater modeling efforts in karst aquifers must, therefore, not rely on composite age dates for travel-time calibration/validation because they do not accurately represent conduit residence times. It is imperative that model designs honor the dual/triple permeability nature of the aquifer using travel-time data collected from the conduits and matrix and/or fracture permeability data collected from other testing methods.

Moreover, quantitative tracing also promises to bridge the gap between tracing and modeling because the resulting hydraulic data can significantly improve model calibrations. We chose the quantitative approach in the Woodville Karst Plain (WKP) for precisely that reason. The WKP is a broad lowland that extends from just south of Tallahassee, Florida to the Gulf of Mexico, where the Floridan Aquifer is either unconfined or poorly confined and contains several large fully saturated conduits, 10-80 m in diameter, approximately 80 m deep, and as much as 15 km long. Water in these conduits flows from local disappearing streams and upland groundwater recharge areas, through numerous karst windows to springs that discharge more than 15 m3/s on average. Logistical problems with quantitative tracing in the WKP include: large but variable residence times in karst windows, dilution along convergent flow paths, extremely large spring discharges, tannic water in the disappearing streams, and numerous potential pathways. To address these problems, tubing was run into the actual conduit flow paths from the karst windows. The tubes were used for water sampling and, in some cases, injections. Estimated discharges and cave maps were used to calculate the minimum requisite tracer quantities such that breakthrough curves would be easily detectable yet well below the visible concentration. Tracer breakthrough curves, from more than five tracer tests, have established minimum conduit groundwater velocities of between 800 and 6000 m/day over minimum flow paths of up to 16 km long. Data based on between 20% and 90% mass recoveries have yielded longitudinal dispersivities of between 12 and 75 m, Reynolds numbers of between 185,000 and 750,000, and Peclet numbers of around 250. These data represent the first quantitative description of conduit flow in the WKP and are now being used to construct and more precisely calibrate groundwater models that effectively address flow to and flow along the known saturated conduits in the basin.

During the summer of 2007 this spring system was observed to have significantly reduced flow due to persistent drought conditions. Our examination of the springs revealed that the salinity of the springs' waters had increased significantly, from 4 in 2004 to 33 in July 2007 with anomalous high radon ( (super 222) Rn, t (sub 1/2) =3.8 days) in surface water concentrations indicating substantial saltwater intrusion into the local aquifer. During our investigation from August 2007 to May 2009 we deployed on an almost monthly basis a continuous radon-in-water measurement system and monitored the salinity fluctuations in the discharge area. To evaluate the springs' freshwater flux we developed three different models: two of them are based on water velocity measurements and either salinity or (super 222) Rn in the associated surface waters as groundwater tracers. The third approach used only salinity changes within the spring area. The three models showed good agreement and the results confirmed that the hydrologic regime of the system is strongly correlated to local precipitation and water table fluctuations with higher discharges after major rain events and very low, even reverse flow during prolong droughts. High flow spring conditions were observed twice during our study, in the early spring and mid-late summer of 2008. However the freshwater spring flux during our observation period never reached that reported from a 1970s value of 4.9X10 (super 6) m (super 3) /day. The maximum spring flow was estimated at about 3.0X10 (super 6) m (super 3) /day after heavy precipitation in February-March 2008. As a result of this storm (total of 173 mm) the salinity in the spring area dropped from about 27 to 2 in only two days. The radon-in-water concentrations dramatically increased in parallel, from about 330 Bq/m (super 3) to about 6600 Bq/m (super 3) . Such a rapid response suggests a direct connection between the deep and the surficial aquifers.

The tracers were injected into a radial-convergent flow field (monopol-test). Two newly developed fluorescent dyes and colloid tracers (D1, D2, C1) were used (Einsiedl et al., 1999a,b). The tracer breakthrough curves were observed in pumping wells located at a distance of 6.2 m and 10.2 m. The tracer experiments were evaluated using the Single Fissure Dispersion Model (Maloszewski & Zuber, 1985), which considers the convective-dispersive flow in the fracture (mobile water) and diffusion of tracer into the porous matrix (stagnant water). The results of earlier experiments performed at the Lindau Test Site have demonstrated that one of the newly developed fluorescent dyes (D1) has a conservative behaviour and can be used as a reference (ideal) tracer. The second tracer (D2) was found to be subject to sorption processes. This result was contrary to those of earlier experiments performed under similar conditions at the Grimsel Test Site (Switzerland) where the tracer (D2) was transported conservatively (Einsiedl et al., 1999a). The reason for the sorption of the D2-tracer was the lower pH-value of water in fractures at the Lindau Test Site. To examine the matrix diffusion process a multi-tracer experiment was performed in which the fluorescent dye (D1) and a colloid tracer (C1) were injected. The colloids, ranging in size of about 5 mu m, were detected with a fluorimeter. The experiment with the colloid tracer (C1) showed that the developed colloidal particles migrated at a velocity greater than the average flow velocity in the capillary tube, and that the tailing effect can not be explained only by tracer diffusion into the matrix.

Nonetheless, assessments of aquifers in limestone and dolomite where contamination issues exist continue to be regularly mismanaged by practitioners whose training has focused on the properties of granular aquifers. Incorrect assumptions of pressure and pore-space continuity, erroneous assumptions of isotropy and homogeneity relating to permeability testing, and the inappropriate application of models and computer simulations based upon these assumptions are the principal causes of this mismanagement. The authority conferred by respected consulting firms and sophisticated computer simulations has led to these fundamentally flawed studies being utilized in situations involving contaminants where the public health and welfare must be appropriately protected. Examples of the misuse of assumptions and authority relating to karst aquifers are discussed here. AD - Ewers Water Consultants, Richmond, KY, United States; U. S.

As such, hydrologic tracing is an essential tool that is commonly used to establish flow trajectories, to understand solute-transport processes, and to develop human health and ecological risk assessments. Unfortunately, the use of anthropogenic materials to trace the flow of water may also impart another source of risk to human health and the environment. In general, attempts are usually made to deliberately release tracer agents at concentrations far below their recognized toxic levels. Ecotoxicologically safe levels for injection concentrations of fluorescent tracer agents are generally set at levels far below that which are necessary to maintain measurable downstream concentrations. Appropriate tracer test design is important, because incorrect tracer-mass estimates may result in the release of larger tracer masses than are necessary and that exceed expected environmental concentrations (EECs). To maintain tracer concentrations at or below accepted levels, optimal tracer-test design is essential and may be achieved using the Efficient Hydrologic Tracer-Test Design methodology. By applying an optimal tracer-test design, it is more likely that downstream tracer EECs will be maintained at or below accepted concentrations while maintaining sufficiently high downstream EECs necessary for positive tracer detection.

This successful endeavour confirmed the hypothesis of a hydrological communication with the springs of Alpe du Lauzet. Hence we warned the owners of chalets and cabins about the possibility of contaminated spring water. A link with the springs of Plan Chevalier remains possible, but a lot less direct and fast.

Viruses contained in the effluents pose a threat to groundwater quality if the weathered bedrock materials do not possess the properties necessary to treat the effluents before they reach groundwater. The extent and pathways of water flow and virus transport in fractured, weathered granitic bedrock were investigated at a field site in Southern California. A suspension containing MS-2 bacteriophage, sodium bromide, and blue dye was ponded at the soil-weathered bedrock interface and allowed to infiltrate for 9 h. A trench was excavated, and bedrock samples were collected and assayed for water, bromide, and MS-2 content. Distributions of dye, bromide, and MS-2 indicate that joint fractures facilitated the channeling of water and of viruses to depths >105 cm. Infiltration data suggest that fracture channeling occurred primarily during the first 50 min, after which time vertical convective flow through the bedrock matrix was the primary infiltration and transport process. The transition from fracture to matrix flow was the result of a decrease in fracture aperture caused by the swelling of pedogenic clay in the weathered bedrock matrix. Bromide and MS-2 concentration profiles suggest that the lower extent of matrix flow was 45 cm, below which water flow and virus transport occurred solely via fracture channeling. These results indicate that caution should be used when operating OSWDS on weathered granitic bedrock in California, and emphasize the need to collect morphologic and hydraulic data prior to their installation.

As GIS, GPS, and web tools became more accessible to resource managers in the 1990s, the need for a statewide, web-accessible, and GIS-compatible karst feature inventory and database has become increasingly evident. A GIS-based database management system was developed to manage and analyze karst feature inventories at both county and statewide scales. Our research focused on the development of the GIS-based Karst Feature Database of Southeastern Minnesota, statistical analyses and hypotheses tests of karst feature distribution and sinkhole formation, and 2D and 3D visualization of karst feature distribution using data from the karst feature database. Hydrogeologic, dye trace, and chemical and isotopic data are included in the database. The main goals of this interdisciplinary research are as follows: 1) to look for large-scale patterns in the sinkhole distribution; 2) to conduct statistical tests of hypotheses about the occurrence of sinkholes; 3) to develop geomorphic and hydrogeologic criteria for land-use decisions in karst areas of southeastern Minnesota and to encourage those criteria's incorporation into relevant environmental regulations; and 4) to develop GIS and database management tools for land-use planners and karst researchers aimed at establishing karst feature databases - at both regional and national scales.

A method is proposed for the interpretation of qualitative tests based on natural background fluorescence obtained with charcoal detectors. The results of connection tests between sinkholes and springs showed that at least three karst conduit networks are responsible for plateau drainage: one of convergent structure (Areias), one of divergent structure (Corrego Fundo) and one whose structure has not yet been determined (Bombas). The results show that the detection of hydrologic connections with rhodamine FWT and activated charcoal is viable in the karst landscapes located in rain forests of southeast Brazil.

The regulatory impetus was the location of a major spring, regionally downgradient from the facility, used as a municipal drinking water supply. A well drilled strategically in the area of highest concentrations of volatile organic compounds (VOCs) of the stable plume was used as the point of injection of fluorescein. Charcoal packets and water samples were collected from 29 locations (on-site monitoring wells, monitoring wells and production wells at an adjacent facility, surface water sites, and the major spring--a diffuse flow conduit spring with three points of emission). The bedrock fracture system in the vicinity of the facility is not well-developed or well-connected. The distances from the injection point to monitoring/sampling locations ranged from 45.7 m (150 ft) to 4.9 km (3.05 miles). The duration of the test, including pre-injection monitoring, was 118 days. A cocktail of potable water (7182 l or 1900 gal) preceded the injection of the dye solution, and a chaser of about 4158 l (1100 gal) followed the injection of fluorescein. The initial movement of the dye was a combination of the head, created by the injection of drinking water and dye, and the non-pumping conditions at the adjacent facility. Within less than 24 h, the imposed head dissipated and water levels in the injection well returned to pre-injection levels. The head imposed or induced with injection resulted in an almost unique occurrence, which pushed water out to the northwest fractures, in pathways other than normal. The only other time that those northwest pathways were probably used, temporarily completing the connection between the facility and the major spring, was when the pond failed, and a slug of VOC-bearing water was induced into the ground water system.

(Energy Systems) manage a closed hazardous waste disposal unit the Chestnut Ridge Security Pits (CRSP), located on the crest of Chestnut Ridge near the Y-12 Plant, Oak Ridge, Tennessee. To investigate the discharge of groundwater from CRSP to springs and streams located along the flanks and base of Chestnut Ridge, an initial dye-tracer study was conducted during 1990. A hydraulic connection was inferred to exist between the injection well (GW-178) on Chestnut Ridge and several sites to the east-northeast, east, and southeast of CRSP. A second dye-tracer study was conducted in 1992 to verify the results of the initial test and identify additional discharge points that are active during wet-weather conditions. No definitive evidence for the presence of dye was identified at any of the 35 locations monitored during the second dye study. Although interpretations of the initial dye test suggest a hydraulic connection with several sites and CRSP, reevaluation of the spectrofluorescence data from this test suggests that dye may not have been detected during the initial test. A combination of relatively high analytical detection limits during the initial test, and high natural background interference spectral peaks observed during the second test, suggest that high natural background emission spectra near the wavelength of the dye used during the initial test may have caused the apparently high reported concentrations. The results of these two tests do not preclude that a hydraulic connection exists; dye may be present in concentrations below the analytical detection limits or has yet to emerge from the groundwater system. The dye injection well is not completed within any significant karst features. Dye migration therefore, may be within a diffuse, slow-flow portion of the aquifer, at least in the immediate vicinity of the source well. AN - OCLC: 68553634 Provider: OCLC AU - Goldstrand, P. M.

In order to protect these fragile and dynamic areas, efficient diagnostic methods must be adapted for use in complex karst settings. While application of surface geophysical techniques to karst problems is not new, its use to delineate possible flow paths of clean water is. This study examines stream loss in a small tributary of the Youghiogheny River known as Hoyes Run in Garrett County, Maryland. The stream bounds the pit of the Deep Creek limestone quarry, operated by Keystone Lime Company. During low flow, the stream abruptly terminates in a swallet, leaving approximately 300 m of dry bed. Two other zones of loss were located during periods of higher flow. Multiple resistivity profiles using the SuperSting (super TM) Resistivity System were generated along the zone of stream loss. A 3-D model of possible void space corresponding to resistivity response was generated using EMIGMA (super TM) geophysical interpretation software. The resulting polygon suggests that a sizable void exists between the stream loss zone and the quarry pit. Dye trace using fluorescein (super TM) confirmed the flow path of water from the stream into the quarry. Geologic examination of the area reveals several sizable known caves developed in the same limestone sequence {Greenbrier Formation, Loyalhanna Member (Ml)}; however, there are no known cave entrances in the immediate vicinity. Borehole confirmation is slated before remediation measures are executed. A possible repeat of the resistivity profiles utilizing attenuation enhancing salts injected into the groundwater is being considered to improve signal density. The study suggests that surface geophysics coupled with computer-based modeling can locate possible flow paths for groundwater in a karst aquifer, even in the absence of obvious karst surface expression.

A number of tracer studies utilized bacteriophage to determine wastewater/groundwater movement were successfully conducted in the State of Florida at a number of coastal and inland sites (The Florida Keys, Chassahowitzka, Florida and Groveland, Florida). These studies determined the impact of septic systems and shallow injection wells on surrounding surface and ground water quality. A common trend that was noted in these studies was that the phage tracers typically moved faster than dye tracers that were or had been utilized in the same regions for similar purposes. One of the conclusions from these studies was that phage tracers better reflect actual microbial movement in ground waters. This presentation outlines the most useful bacteriophage tracers and methodology to determine microbial transport and viability. Issues such as source tracking, selection of the appropriate bacteriophage and the factors, which affect microbial transport and survival, will be described. AD - U. S.

Many buildings stand on the Akiyoshi-dai, about 100 m above the cave stream. The investigation about the drainage system around the Shuho-do area was conducted to collect the basic data those are available for the preservation of nature. The main research method is the fluorescent dye injection and tracing by the rainwater flow. All the rainwater that fell on the hill is drained from the springs of Shuho-cave or this neighborhood. A spread of the karst hydrologic area is complicated, and the fluorescent dye thrown into one spot on the hill is drained from two or more springs. It is presumed that it spreads and spreads with an intermediate vadose zone below the limestone plateau. The dividing caves in Shuho-do cave are important for a spread of the discharge area, and vadose water once gathers for dividing caves, and joins a main stream.

AB - We compared velocities of the subsurface flow from a mounded onsite septic system towards a depressional wetland with three types of tracer; an inert gas, sulfur hexafluoride (SF (sub 6) ), two fluorescent dyes, fluorescein and rhodamine WT, and a viral tracer, the bacteriophage PRD-1. The movement of both fluorescent dyes was significantly retarded in the soils compared to both SF (sub 6) and PRD-1. In experiments using injection solutions containing both a dye and SF (sub 6) , fluorescein was found to move at least 3-4 times slower than SF (sub 6) , and rhodamine was not observed away from the drainfield. In contrast, the velocities calculated from SF (sub 6) data are very similar to the velocities calculated from the PRD-1 data obtained during the same experiment. At a second site, the movement of fluorescein was half as fast and not as extensive as the movement of SF (sub 6) . The results of these experiments indicate that fluorescent dyes may underestimate velocities of effluent from septic systems adjacent to seasonal wetlands. In contrast, SF (sub 6) was found to perform similarly to the viral tracer PRD-1. AD - Florida State University, Department of Oceanography, Tallahassee, FL, United States AU - Harden, Harmon S.

The most prominent sinks and springs in the Mississippian Monteagle Limestone on the floor of Lost Cove along Lost Creek have been monitored over the past year to study the effects of a fluctuating water table. During periods of heavy rain, a rising water table activates ephemeral springs and streams found throughout the floor of Lost Cove. Most of the water ultimately reaches the Big Sink, where it drops 40 m over the next 1.2 km in the Buggytop Cave system and emerges as Crow Creek. Detailed subsurface maps of the Cove are preliminary, and have not yet demonstrated that all surface water enters the Buggytop system. Dye tracing in major sinks and springs of a major tributary, Champion Cove, is underway but has already demonstrated there is no direct connection between Prince Spring and the major upstream sink to the northeast. Older dye traces on the eastern end of Champion Cove at Temple Sink suggest no direct connection to the Lost Cove, Big Sink, or Buggytop systems. Other groundwater flowlines throughout lower Lost Cove continue to be traced and mapped. Future work will include a comparison between calculated and observed recharge and discharge throughout Lost Cove.

We hypothesize that migration of agrichemicals to aquifers occurs through fracture networks in the overlying till. To evaluate the potential for fractures to transmit contaminants through till, we collected large (0.45 m diameter by 0.45 m length) intact columns of visibly fractured till and conducted solute transport experiments in the laboratory. Eight columns representing one late Wisconsinan and three Pre-Illinoian till units were collected from three sites in Iowa, ranging in depth from 1 to 27.5 m. Fractures observed at the late Wisconsinan till site were oriented perpendicular to ice-flow direction, suggesting formation from extensional stress during or shortly after glaciation. The much older Pre-Illinoian till fractures formed polygonal networks and were presumably generated by desiccation during interglacial periods. Laboratory solute transport experiments indicate that fractures influence solute transport by increasing bulk hydraulic conductivity (K) and reducing effective porosity. The K of the columns ranged from 3.8E-5 to 7.7E-10 m/s. Experiments using several conservative tracers (Br, PFBA, and PIPES) resulted in first-arrival velocities between 7.5 and 144 m/day for columns less then 2 m deep and 0.1 to 0.002 m/day for columns greater than 2 m deep. These higher than expected velocities suggest that solute advection occurred primarily through fractures. Further evidence of fracture-dominated flow was provided by dye-trace studies. The non-conservative agrichemicals nitrate and atrazine traveled as rapidly as conservative tracers in shallow columns, but were either degraded (nitrate) or sorbed (atrazine) in deeper columns where residence times were much longer. Breakthrough curves generated by discrete fracture and dual-continuum models using independently determined input parameters closely approximated the observed data (R (super 2) >0.9). Thus, models provide useful tools for predicting solute transport through fractured till. In conclusion, the till units in Iowa contain hydraulically active fractures capable of transporting contaminants from the land surface to underlying aquifers, and should be considered in any evaluation of aquifer contamination potential.

We used an intermediate-scale 2D flow cell (2.44X1.53X0.108 m) packed with a fine silica sand to investigate surfactant-induced flow perturbations. Surfactant solution (7% 1-butanol and dye tracer) was applied at a constant rate at a point source located on the soil surface above an unconfined synthetic aquifer with ambient groundwater flow and a capillary fringe of approximately 55 cm. A glass plate allowed for visual flow and transport observations. Thirty instrumentation stations consist of time domain reflectometry probes and tensiometers measured in-situ moisture content and pressure head, respectively. As surfactant solution was applied at the point source, a transient flow perturbation associated with the advance of the surfactant solution was observed. Above the top of the capillary fringe the advance of the surfactant solution caused a visible drainage front that radiated from the point source. Upon reaching the capillary fringe, the drainage front caused a localized depression of the capillary fringe below the point source because the air-entry pressure decreased in proportion to the decrease in surface tension caused by the surfactant. Eventually, a new capillary fringe height was established. The height of the depressed capillary fringe was proportional to height of the initial capillary fringe multiplied by the relative surface tension of the surfactant solution. The horizontal transport of surfactant in the depressed capillary fringe, driven primarily by the ambient groundwater flow, caused the propagation of a wedge-shaped drying front in the downgradient direction. Comparison of dye transport during the surfactant experiment to dye transport in an experiment without surfactant indicated that because surfactant-induced drainage decreased the storage capacity of the vadose zone, the dye breakthrough time to the water table was more than twice as fast when the contaminant solution contained surfactant. The extensive propagation of the drying front and the effect of vadose zone drainage on contaminant breakthrough time suggest the importance of considering surface tension effects on unsaturated flow and transport in systems containing surface-active organic contaminants or systems, where surfactants are used for remediation of the vadose zone or unconfined aquifers.

However, for some karst scientists, only a dye trace gives unambiguous proof of water flow. To our knowledge there has not been a successful dye trace from conduit to matrix, despite careful attempts. We will attempt several dye traces to detect flow from conduit to matrix in Wakulla Spring Cave, near Tallahassee, Florida. Rather than attempting to detect the dye in wells near the conduit, we will place dye receptors in narrow boreholes drilled (< 1m) into the matrix from conduit wall. This will require underwater coring and instrumentation of the core holes with a multilevel sampler. We have developed both sets of hardware for this application. A reviewer of our tracer test called it "some of the most delicate work I've seen proposed". We would like to improve the test design and are actively soliciting comments and suggestions. There will be prototypes of the underwater pneumatic drilling system and multilevel sampler at the poster. The poster will describe our evolving experimental plan, and show our preliminary computational fluid dynamics modeling of dye injection and sampling extraction. Engineering plans for the pneumatic drilling system and multilevel sampler will be available at the poster.

A2 - Trautz, Robert C. A2 - Wang, Joseph S. Y. AB - Field and laboratory tracer experiments were conducted to investigate the extent of tracer imbibition and penetration into unsaturated, fractured rock matrix at Yucca Mountain, Nevada. Field experiments were carried out in the Exploratory Studies Facility (ESF), an underground tunnel at Yucca Mountain. Water containing dye was released into horizontal boreholes drilled into the wall of the ESF main drift. The region was then mined to observe the flow pathways and to collect dye-stained rock samples for subsequent laboratory quantification. Dye concentration profiles in the rock, measured using a newly developed sampling technique, showed that liquid flowing through the fractures penetrated into the matrix to a depth of several millimeters. Laboratory studies of tracer penetration into the rock matrix were conducted using tracer-free rock samples, collected from the same hydrogeologic unit and machined into cylindrical cores. Tracer-imbibition tests were performed on cores at two different initial water saturations with both sorbing (dyes) and nonsorbing tracers. The travel distance for sorbing dyes was a few millimeters after 16 to 20 h, similar to the extent measured in samples from the field test. The nonsorbing bromide front coincided with the wetting front in the rock core at the initial water saturation of 12%, and the imbibition depth agreed very well with the prediction, using independently measured properties. At the high initial water saturation of 76%, the bromide front lagged significantly behind the wetting front. Sorption coefficients for the dyes in the partially saturated core samples were calculated using two independent approaches, based on tracer travel-distance and mass-distribution calculations, and were found to yield comparable results. Utilization of nonsorbing tracers with different molecular sizes helped to identify the effects of pore-size restriction on tracer transport during imbibition. The results from this work have a direct application to radionuclide transport at Yucca Mountain, and the methods presented are broadly applicable to the investigation of water and solute transport in unsaturated rock.

Locations of these groundwater flow routes and velocities of groundwater flowing along the routes were determined by injecting fluorescent, non-toxic, organic dyes (Fluorescein and Eosine) into two caves within Onion Creek, the largest capacity losing stream in the Barton Springs segment of the Edwards Aquifer. Cripple Crawfish and Antioch caves are located about 17.5 mi and 14.0 mi south of Barton Springs, the primary discharge point from the aquifer, respectively. First arrival of dyes from each of these caves to Barton Springs occurred after about 3.5 and 7.0 days, indicating minimum groundwater velocities under high spring flow and water-level conditions of 5.0 and 2.0 mi/day, respectively. Dye detections at water-supply wells indicate a karst system composed of multiple diverging flow routes from these caves, which appear to re-converge as groundwater flows northeast discharging at Barton Springs. Interpreted flow paths are oriented normal or parallel to potentiometric contours, indicating a highly anisotropic flow system consisting of conduits. Conduit flow within the aquifer appears to be strongly influenced by the bimodal fault and fracture system with trends of N40E (dominant) and N45W (secondary). Groundwater flow was traced in wells along paths that are parallel to the dominant fault trend presented on geologic maps. Groundwater flow was also traced parallel to the secondary structural trend, at a high angle to the dominant mapped fault trend. Results indicate that conduits are an important component of flow, and that the bimodal structural grain has influenced conduit flow in this aquifer. Future numerical groundwater models incorporating conduit flow should consider, among other data, structural grain for modeling the distribution and orientation of conduits.

Tidal fluctuations can result in significant changes to the flow system, especially in the vicinity of the discharge zone. If the coastal environment includes surface water bodies, interactions between the surface water and fresh-to-saline groundwater result in complex daily and seasonal effects. These interactions were investigated at a site located within the City of North Miami, Florida as part of the development of a former landfill into a high end residential/commercial development. The site includes several freshwater lakes adjacent to a mangrove system consisting of both fresh and saline surface water and groundwater ultimately discharging to Biscayne Bay. Hydraulic characteristics were obtained from a variety of aquifer tests and natural gradient tracer tests that were primarily conducted with rhodamine dye. Qtracer and SEAWAT 2000 were used to analyze the tracer tests. SEAWAT 2000 was also used to model groundwater flow under various seasonal periods including the five-year and 25-year storm events, which results in the injection of surplus storm water into the Biscayne Aquifer. The model demonstrated that the groundwater flow system is significantly altered by the presence of, and the associated water level fluctuations in the lakes, especially during the storm events. Vertical flow and mass transport is significantly increased as a result of the lakes and associated seasonal fluctuations. The density of brackish water in the mangroves would be expected to result in vertical flow. However, the mangrove system appears to limit vertical discharge due to the low permeability sediments deposited in this environment. Organic decomposition of the landfill material has generated an ammonia plume whose treatment was evaluated with an experimental prototype permeable reactive barrier. Various models of this environment have also been used to simulate full-scale remedial combinations of slurry walls and reactive barriers.

They all fluoresce with a similar stokes shift, allowing for simultaneous examination of environmental samples with a synchronously scanning spectrofluorometer. Different functional groups on the base structure for these dyes control the wavelength of fluorescence. Most rhodamine dyes have two alkylated-amine groups at different locations on the base structure. Their location and that of other functional groups control the fluorescence wavelength of the dye. Removal of the alkylated-amine functional groups is referred to as "deaminoalkylation" and will shift the fluorescence to lower wavelengths. Deaminoalkylation of rhodaine WT (DAR WT) appears to have two possible degradation products with different fluorescence wavelengths. One of these can interfere with the analysis or be mistaken for fluorescein, and the other has similar consequences for eosine. The formation of DAR WT has been observed to form in as short a time as one month in groundwater tracing studies, but does not occur in every use of rhodamine WT. DAR WT has not been observed in laboratory standards. In some cases the rhodamine WT and the DAR WT have been recovered at a sample point simultaneously and in other cases only the DAR WT has been observed. DAR WT has been recoverable at least 12 years after the original injection of the parent dye and appears to be very stable after it has formed. The presence of DAR WT in a sample that is being analyzed with a filter fluorometer could easily give a false positive for fluorescein due to its similar fluorescence peak wavelength. Misidentification of DAR WT may have been common with early spectrofluorometers. Reexamination of past groundwater tracing results with current equipment and an understanding of the existence of DAR WT has resulted in recovery of lost rhodamine WT traces and corrected apparently successful traces improperly ascribed to fluorescein. Similar changes in dye characteristics have been observed by groundwater tracing practitioners in Europe for rhodamine B and likely occurs for the other rhodamine dyes.

J. A2 - Musy, A. A2 - Talamba, D. AB - The objective of this research is to improve the comprehension of the hydrological behavior of natural catchments. The main originality of this work is to associate different types of measurement in order to obtain a better vision of hydrological processes responsible for streamflow generation. First, the hydrological behavior is studied at the catchment scale by the application of environmental tracing. A three-component mixing model based on the silica and calcium concentrations of water allows one to distinguish the contributions of direct precipitation, soil water and groundwater during flood generation. Despite the different hydrological responses observed between the four subcatchments studied, a common behavior is apparent. Soil contribution increases with a rise in the basin humidity. The subsurface water dominates the generation of major floods, which occur in wet conditions. In order to discover the processes responsible for the important soil water contributions, a large-scale time-domain reflectometry experiment (64 probes) was conducted. On the whole, this experiment indicates that the water flow in soil is spatially quite heterogeneous and depends on local properties. Macropore flows were clearly identified during a rainfall simulator experiment. Preferential flows may be responsible for the important contribution of soil water and the heterogeneity of the soil moisture. In order to test this hypothesis, a dye-tracing experiment was done. This new investigation confirms that an important part of soil water reaches the stream by preferential flows. So as to synthesize all these observations, a conceptual model is proposed. This model respects both the hydrochemical responses highlighted by the environmental tracing experiment and the observations done at the local scale. This conceptual model suggests that the important contribution of soil water is due to the extent of the hydrographic network and the role of preferential flows.

Reliable numerical models for assessment of groundwater contamination from such aquitards are needed for planning, regulatory and remediation purposes. In this investigation, high resolution preferential water-saturated flow and bromide transport data were used to evaluate the suitability of equivalent porous medium (EPM), dual porosity (DP) and discrete fracture/matrix diffusion (DFMD) numerical modeling approaches for assessment of flow and non-reactive solute transport in clayey till. The experimental data were obtained from four large undisturbed soil columns (taken from 1.5 to 3.5 m depth) in which biopores and channels along fractures controlled 96-99% of water-saturated flow. Simulating the transport data with the EPM effective porosity model (FRACTRAN in EPM mode) was not successful because calibrated effective porosity for the same column had to be varied up to 1 order of magnitude in order to simulate solute breakthrough for the applied flow rates between 11 and 49 mm/day. Attempts to simulate the same data with the DP models CXTFIT and MODFLOW/MT3D were also unsuccessful because fitted values for dispersion, mobile zone porosity, and mass transfer coefficient between mobile and immobile zones varied several orders of magnitude for the different flow rates, and because dispersion values were furthermore not physically realistic. Only the DFMD modeling approach (FRACTRAN in DFMD mode) was capable to simulate the observed changes in solute transport behavior during alternating flow rate without changing values of calibrated fracture spacing and fracture aperture to represent the macropores.

We present results from infiltration experiments on four heterogeneous field plots (Orthic Luvisol) for plowed and nonplowed conditions. A 2-mm pulse of Br (super -) was applied, followed by a 40-mm application of a 5 g L-1 solution of the food dye Brilliant Blue FCF (Color Index 42090) in a 6-h period. Horizontal cross sections were photographed at 0.05- and 0.10-m depth intervals, representing the Ap and Bt horizons, respectively, either immediately or 90 d after the tracer application. High-resolution spatial maps of Brilliant Blue concentration were derived from the scanned photographs using one single calibration relationship between Brilliant Blue concentration and the color spectra for all plots and depths. No significant or consistent directional dependence was observed in the spatial correlation structure of the dye concentration for the horizontal cross sections. However, the integral scale showed a distinct depth dependency, partially caused by horizonation, with a larger value in the Ap than in the Bt horizon. Disturbed soil samples were taken at 15 locations for each cross section and analyzed for Br (super -) . Although Brilliant Blue was retarded in the soil matrix with respect to Br (super -) , both tracer concentrations showed an exponential decay with depth because of preferential flow enhanced by plowing. Only a small fraction of the dye was subjected to fast transport. The plot-scale information of the dye distribution revealed that our 15 sampling locations at each depth were sufficient to identify the averaged plot-scale transport behavior in the soil matrix, but failed to represent the conducting preferential flow pathways.

The fractures that act as the significant paths of solute movement are termed transmissive fractures, and the location and properties of these fractures must be known for solute transport phenomena to be accurately analyzed. This study proposes semi-analytical solutions for tracer breakthrough curves at any depth in an observation well, at any point in time. These solutions were obtained from successive application of 2-D advective and dispersive transport models in the transmissive fractures, and 1-D diffusive transport model in the observation well. The solutions can be applied to locate the transmissive fracture along an observation well from tracer tests. Once the location of the transmissive fracture is known, the advective and dispersive characteristics of solute transport through the transmissive fracture can be estimated. A graphical method to determine the location of the transmissive fracture and to estimate the diffusive transport along an observation well is proposed. This method has been successfully applied to laboratory tests.

To study this phenomenon, a bromide tracer experiment was performed on a 1.6-ha area of a tile-drained arable field to determine the contribution of preferential flow to solute leaching, and to investigate the factors triggering the onset of such events. During the 2 yr following the application of Br-, concentration of the drainage effluent exhibited a pattern of peaks coinciding with the discharge peaks. The concentration peaks, on top of a smooth base flow, were interpreted as being the contribution of preferential flow. The separation of peak and base flow indicated that 73% of the Br- leached during the 2 years of study was exported through preferential flow. A simple leaching bucket model was able to accurately predict the occurrence of solute peaks in the drain discharge. The analyses indicated that preferential flow originated primarily at the boundary between top- and subsoil as soon as the topsoil became sufficiently saturated. Thus, low intensity, high duration events could also trigger preferential flow. AD - Federal Office for Water and Geology, Hydrological Survey, Bern, Switzerland AU - Kohler, A.

Landa Lake, the lake associated with the springs, went "dry" in the summer of 1956 after several years of extended drought. The "drying up" of the spring-fed lake was pivotal in the lawsuit of the Sierra Club vs U.S. Fish and Wildlife Service in 1992 and its subsequent impact on water management in Central Texas. The hydrogeologic setting of the springs and the history of spring flow were investigated to determine detailed spring plumbing, relative impact of regional and local water users on spring flow during low flow periods, and implications to sustainability of spring flow by aquifer management and spring augmentation. Comal Springs is composed of 8 discrete springs and extensive seepage into the bottom of Landa Lake. The springs are located along the Comal Springs Fault, which separates the Edwards Aquifer into up thrown and down thrown fault blocks. Hydrologic studies, dye traces, and hydrochemistry of the springs indicate that the western springs discharge groundwater from the up thrown block and the eastern springs discharge groundwater from the eastern down thrown block. The sequence of events that caused the springs and lake to go dry was documented by comparing aquifer water levels, lake levels and spring discharge rates to the local historic newspapers articles about the springs. In the 1950's, the western springs went dry when water levels in the up thrown block dropped below the elevations of the individual spring orifices. The eastern spring orifices and the springs in the lake stopped flowing when water levels in the down thrown block dropped below the lake level. Early in the summer of 1956 the lake stopped flowing to the Comal River; lake levels then dropped six feet in less than three months. The rapid lake level drop occurred because excess flow was no longer leaving the hydrologic system as stream flow and lake levels then mimicked the rapidly declining water levels in the confined aquifer. In addition 10-20 cfs of local ground water pumpage from the Edwards was brought on line to supplement local water supplies.

It is the main discharge of an aquifer comprised of the Mississipian limestones belonging to Ste. Genevieve and St. Louis Formation. Previous dye tracing studies defined a 112 km2 watershed situated north of the spring. Large conduits have developed in the carbonate aquifer due to dissolution processes that create a myriad of sinkholes characterizing the Mitchell Plain. Such karst structures determine turbulent flow after intense rain events from the recharge area to the spring. Orangeville Rise was monitored before and during an intense storm event (20mm of rain in 2 hours) which occurred on the 10th of November 2002. The discharge increased almost immediately and reached its maximum on the hydrograph (from less than 1 to 6 m3/s) in 24 hours. Applying linear mixing models to the chemistry of the spring water, the hydrograph separation technique allowed us to quantify contribution percentages to the total discharge. Stable isotopes (oxygen-18, deuterium, sulfur-34, nitrogen-15 and carbon-13) and major ions were used to track three different water sources (rainwater, epikarst and phreatic water). The hydrograph separation shows that 40% of the total discharge is to be attributed to rainwater entering the system during the event; vadose water supplies another 40% throughout the entire flood and phreatic water represents the remaining part. The hydrograph separation also presents an initial piston effect produced by the rain on the groundwater and the vadose water located in the shallow subsurface. The arrival of the highest rain contribution (>50%) occurred when the total discharge approached pre-storm values.

Dye tracer experiments, water-level measurements and observations made while drilling show that nearly all the water passing through this part of the glacier moves through interconnected conduits in a complex karst-like system, in and beneath the thick zone of basal ice and along the base of the glacier. Ten of the holes intersected a hydrologic system at the top of the basal ice, while two of the holes intersected the system before basal ice was reached, most likely through basal crevasses. Two dye tracer tests were performed, where dye injected into a single borehole was recovered at multiple vents discharging at the terminus of the glacier. The velocity of the subglacial water varied, with a maximum velocity of 0.13 m/s over a straight line distance of 198 m and a minimum velocity of 0.03 m/s over a 40 m straight line distance. These results indicate that water in this part of the glacier moves through a distributed system, consisting of both major and minor conduits, that are connected by the porous basal ice. Borehole water levels remained near the ice surface indicating that the piezometric pressure is near that of the ice overburden pressure and that the water table followed the ice surface profile. However, the ice topography in the study area is highly variable, leading to local areas where the piezometric surface is above the ice surface. Several boreholes discharged large amounts of water from the subglacial system for several days following drilling, indicating high pressure, perhaps due to the local hydraulic resistance of the porous basal ice. Water levels fluctuated slightly on a diurnal cycle, indicating that the subglacial system is fed by surface meltwater.

Heterogeneity can give rise to non-Fickian transport patterns, which are distinguished by "anomalous" early arrival and late time tails in breakthrough curves. Experiments were conducted in two mid-scale laboratory flow cells packed with clean, sieved sand of specified grain sizes. Three sets of experiments were performed, using a "homogeneous" packing, a randomly heterogeneous packing using sand of two grain sizes, and an exponentially correlated structure using sand of three grain sizes. Concentrations of sodium chloride tracer were monitored at the inflow reservoir and measured at the outflow reservoir. Breakthrough curves were then analyzed by comparison to fitted solutions from the ADE and CTRW formulations. In all three systems, including the "homogeneous" one, subtle yet measurable differences between Fickian and non-Fickian transport were observed. Quantitative analysis demonstrated that the CTRW theory characterized the full shape of the breakthrough curves far more effectively than the ADE.

In south-central Pennsylvania, karst aquifers commonly are covered by a mantle of unconsolidated materials that can obscure the surface expression of karst features, thus making it difficult to locate where a contaminant can be directly introduced into the aquifer. The combination of unconsolidated materials, fractures, and conduits results in a multi-velocity flow field with components ranging from slow to rapid. Recent studies of two springs in a carbonate aquifer in south-central Pennsylvania used different methods to identify slow and rapid components in spring discharge. Traditional methods showed that both springs had a deep, slow-moving, diffuse source of water; however, other methods showed that these springs also had a component of discharge that moved rapidly through the aquifer. For example, at one spring, continuous monitoring of temperature and specific conductance during storms provided the evidence of rapid flow through the aquifer. At the other spring, a dye-tracing study linked the spring to a sinkhole 5 miles away with the initial breakthrough in 5 days, indicating flow rates several orders of magnitude faster than previously published values. The flow direction was parallel to strike, which differs about 90 degrees from the flow direction determined by other methods. These results provide an invaluable insight to the understanding of the mantled karst aquifer. In some cases, the unconsolidated mantle and fracture system overlies the conduit system, providing storage, attenuating traveltime, and feeding the conduit system below. In other parts of the same system, the conduit system receives water directly from the surface and transmits it rapidly to the spring. Because the contribution of the conduits that bypass the slower part of the system is a small percentage of the total flow and is also transient, this part of the system could be easily missed; however, when it is active it dominates the potential for contaminant transport. Traditional hydrology would need to be supplemented with karst studies to provide the understanding of where the rapid transport component completely bypasses the other parts of the system. AD - U.

These preferential flow channels are believed to be responsible for the non-Gaussian transport behavior over several hundreds of meters observed during three previous natural-gradient tracer experiments. To provide further field evidence of preferential flow channels and quantify their effects on subsurface solute transport, a couple of tracer tests have recently been conducted at the MADE site. The first test is a single-well injection-withdrawal (SWIW) experiment, and bromide is used as the conservative tracer. The bromide breakthrough curve is very asymmetric and shows an early-time high peak followed by extensive low-concentration tailing during the late recovery stage. Initial analyses indicate that the data collected from the SWIW test can be used as the basis to estimate the parameters required by the dual-domain mass transfer model in order to reproduce the observed plume behaviors in previous natural-gradient experiments at the site. In the second test, a dye tracer (Brilliant Blue FCF) is injected into the aquifer and 20 soil cores are subsequently collected in the vicinity of injection well. The soil cores are visually inspected in an attempt to construct a three-dimensional preferential flow channel network by correlating the dye distribution between different soil cores.

Standard tracing techniques use Rhodamine WT, uranine and eosin dye, carbon samplers and direct water samples and scanning spectrofluorophotometry with spectral peak analyses to document selected sinkhole to spring connections. The sinkhole distributions are mapped from digital orthoquads and then supplemented with features not visible on the orthoquads with fieldwork using GPS techniques. Structural contour maps of the bottom of the carbonate units are constructed using a critical reevaluation of water well logs in Minnesota's County Well Index by comparison to gamma logs and outcrops. The initial results show springsheds with a few km2 area. Mapping of springsheds can help encourage implementation of Best Management Practices to protect and improve the water quality in the springs. The springs are used as livestock water supplies, and recharge deeper aquifers in nearby settings, which are used for municipal water supplies. The structural contour maps and refined geologic maps demonstrate that the dense arrays of sinkholes have formed where the Stewartville Formation is the first bedrock and in the areas of highest local dip. The regional dip is roughly 1:1,000 but the sinkholes are concentrated in the areas where the dips are close to 1:100.

The spring is located in tall-grass prairie and the dominant land use is cattle ranching. Crystal spring is fed by ground-water discharge from three sources moving through Permian Barneston Fm. limestones: 1) confined regional flow, 2) diffuse recharge from the Barneston outcrop, and 3) focused recharge through stream-bottom sinkholes in Martin Creek within the outcrop. Higher Cl, SO4, and SO4/Cl ratios and low dissolved organic carbon (DOC) distinguish regional flow. Recharge from diffuse and focused sources has lower Cl, SO4, and SO4/Cl ratios, but focused recharge contains much higher DOC than diffuse recharge. Nitrate in spring discharge ranges from 2 to 5 mg/L. High-amplitude fluctuations in spring discharge are directly tied to precipitation events in the up-gradient Martin Creek drainage basin. Wetter periods and high rainfall-producing storms at other times rapidly escalate spring discharge to rates >142 L/s. Dye trace studies of the sinkholes in Martin Creek yield travel times of <43 hrs to Crystal spring 4.8 km away and suggest a well-developed conduit system in the limestone aquifer. Water-level data from monitoring wells near the sinkholes shows rapid development of a recharge mound in the adjacent aquifer during wet periods and the gradual loss of water in storage from the conduit system beneath the stream to the spring in the ensuing dry periods. Differences in the fracture/solution channel conduit system between the upper and lower Barneston may explain the apparent water-level behavior. The primary potential source of contamination in the recharge area of Crystal spring is the pasturing of cattle. These findings do not support the need for additional measures to protect water quality at current levels of cattle grazing within the drainage basin above the spring.

AB - Crystal spring issues from the Barneston Limestone (Permian) outcrop belt in Marion County, Kansas, and is one of many high-yielding springs in the Flint Hills region. During this study, spring discharge from karstic aquifer zones ranged from 28.3 to >340 L/s. Observations of the Barneston in a nearby quarry and from core descriptions in the literature indicate significant development of interconnected secondary porosity from dissolution of its contained evaporites in the near-surface environment. Geochemical evidence indicates that Crystal spring is fed by ground-water discharge from two sources moving through the Barneston limestones: (1) diffuse recharge from the Barneston outcrop and confined regional flow, and (2) focused recharge through stream-bottom sinkholes within the outcrop. High-amplitude fluctuations in spring discharge are directly tied to precipitation events in the up-gradient Martin Creek drainage basin. Dye-trace studies indicate that sinkholes in Martin Creek and the spring are hydraulically connected by a well-developed conduit system in the limestone aquifer. Water-level data from monitoring wells near the sinkholes show rapid development of a recharge mound in the adjacent aquifer when there is flow in the creek, and the gradual loss of water in storage from the conduit system in the ensuing dry periods. Differences in the fracture/solution-channel conduit system between the upper and lower Barneston provide an explanation for the apparent water-level behavior.

In the latter case, the exchange of water between conduits and matrix could have important implications for water management and hydrodynamic modeling. An extensive conduit system has been mapped by dye trace studies and cave diving exploration at the Santa Fe Sink/Rise system located in largely unaltered rocks of the Floridan aquifer of north-central Florida. In this area, the Santa Fe River flows underground at the River Sink and returns to the surface approximately 5 km to the south at a first magnitude spring called the River Rise. Limited data show that discharge is greater by 27-96% at the River Rise than at the Sink and that the downstream increase in discharge is inversely related to discharge of the river. Natural SO (sub 4) (super 2-) concentrations indicate that approximately 25% of the water discharging from the Rise originates from the Sink during low flow. Conversely, SO (sub 4) (super 2-) and other solute concentrations indicate that most of the water discharging from the Rise originates from the Sink during floods. Ar approximately 40% decrease in Na (super +) and Cl (super -) concentrations over a 5 1/2-month period at a down-gradient water supply well may reflect flow of dilute flood water from the conduits into and through the matrix at rates estimated to be between 9 and 65 m/day. Calcium concentrations remain constant through time at the well, although flood waters have approximately 90% lower Ca (super 2+) concentrations than ground water, perhaps reflecting dissolution of the matrix rocks. This apparent exchange of water between matrix and conduits is important for regional ground water quality and dissolution reactions.

The Blue Hole karst groundwater basin is located in Woodford County, Kentucky. Previous dye traces in the area have shown that sources for recharge include Big Spring (a swallet located in downtown Versailles) and a sinkhole located on a farm approximately 1 km southeast of downtown. Blue Hole spring emerges approximately 540 m northwest of the Big Spring swallet. To characterize discharge at Blue Hole spring, stream stage and temperature were monitored continuously and discharge measurements were recorded weekly by wading with a current meter. Stream stage was correlated to discharge, building upon a preliminary rating curve developed by the Kentucky Geological Survey. Values of specific conductance (SC) and pH, which were measured weekly with portable meters, ranged from 0.400 to 0.740 ms/cm for SC and from 6.7 to 7.4 for pH. Following a 4.37-cm rainstorm on November 29, 2002, a quantitative dye trace with Rhodamine WT was conducted from Big Spring to Blue Hole spring. The travel time for peak dye concentration was 80 minutes. During a 6.35-cm rainstorm on March 19, 2002, total suspended sediment concentration (TSS), grain size, mineralogy, particulate organic carbon (POC), and discharge were measured at Blue Hole spring. TSS ranged from approximately 113 mg/L at 1.2 m3/s to approximately 975 mg/L at 2 m3/s. For suspended sediment POC varied from 3.7% to 6.1% and average grain size, determined by laser light scattering, ranged from 19 to 31 microns. Whole rock mineralogy of bed and suspended sediment is dominated by quartz; clay mineralogy is being determined. A dual quantitative trace with talc and Rhodamine WT from Big Spring to Blue Hole will be conducted to assess the mobility of clay particles during a subsequent storm.

The Floridan Aquifer System, Florida's primary drinking water aquifer, provides water to the majority of springs in the state. Florida is home to more than 700 springs, 33 of which discharge more than 100 cubic feet per second (first magnitude). In 2001, the Governor established the Florida Springs Initiative (FSI) which provided funding, through the Florida Department of Environmental Protection, for springs research and monitoring, outreach and education, and landowner assistance. The Florida Geological Survey (FGS) has been funded yearly, by the FSI, to conduct research on water quality, water quantity and location of Florida's springs. In 2004, a study was funded jointly by the FGS and FSI to map the distribution of swallets in Florida with primary attention focused on springsheds. The goal of the FGS study is to identify swallets and collect as much pertinent data about these features as possible. These data will be compiled in a database and made available to the appropriate agencies and the public in ARCGIS format. Swallets commonly occur in the transition zone between the upland regions and karst plains in Florida. Many of these features receive untreated storm water and other surface waters directly from urban areas. Florida's springs have seen a steady decline in water quality over the past 30 years due to rapid urbanization, agricultural practices, and the demands for drinking water from a rapidly growing population. It is currently unknown how many swallets exist within spring recharge basins and how they affect water quality of springs. Several studies in the Wakulla and Ichetucknee Springs springsheds have linked swallets to springs using dye tracing. Many more are suspected of having direct connections to springs. Since swallets provide direct access to the aquifer it is important for municipalities, land planners, and other agencies to know where they exist and what role they play in surface-water/groundwater systems.

The city and surrounding developments rely heavily on the Madison Aquifer for drinking-water supplies, utilizing several wells and springs. Within the Black Hills, the aquifer consists of Mississippian limestone and dolostone of the Pahasapa Limestone and contains well-developed Mississippian-Pennsylvanian and early Tertiary paleo-karst and possibly recent karst features. Water chemistry analyses and dye-tracer test results reported by the U.S. Geological Survey indicate that surface water recharge from the Spring Creek watershed to the south and the Boxelder Creek watershed to the north converge on wells and springs in the Rapid City area eight to ten km (five to six miles) away. Spring Creek and Boxelder Creek lose all their flow to karst features in the Madison Aquifer, except during periods of very high discharge (greater than 25 to 30 ft (super 3) /sec). Published and unpublished dye-tracer tests for this area indicate that ground-water velocities are on the order of 300 meters per day (1,000 feet per day) or faster, and residence times can be less than 30 days. Based on this information, the water supply for Rapid City and surrounding areas is extremely vulnerable to natural and anthropogenic contamination. Geologic structures, fractures, stratigraphy, structural contour maps, water-quality data, dye-tracer tests, and human influences are being analyzed to better define local ground-water flow paths and to define vulnerability zones for Rapid City's water supply. Current findings indicate that structural controls (e.g., strongly developed systematic fractures, Laramide folds, and fracture traces) play a major role in ground-water flow.

AB - Soil compaction has long been considered to be a problem in arable land, primarily because it causes damage to soil structure, which can lead to serious reduction in crop yields. However, few studies have sought to investigate the effects of soil compaction on the water transport regime of modified soil pore systems. We attempted to quantify the effects of soil compaction on the initiation of preferential flow by using dye tracers and image analysis. A laboratory methodology involving rainfall simulation enabled us to quantitatively evaluate differences in the mechanisms of water flow between two soil types at several degrees of compaction. The results suggested significant differences in the types of water flow pathways between clay loams and sandy loams at different extents of compaction. In the sandy loam, it was concluded that a high degree of compaction led to an increased likelihood of preferential flow, whereas a more uniform movement of soil water occurred at less compaction. By contrast, preferential routing of soil water was recorded in the clay loam, except at the highest measured compaction. The results indicate that the visual techniques of dye tracing and image analysis could enable improved understanding of flow pathways of soil water associated with soil compaction.

To assess the exchange of water between intergranular and conduit porosity in the Upper Floridan Aquifer, we conducted a quantitative dye trace in the lower portion of the Santa Fe River Sink-Rise system in north-central Florida. At base-flow conditions, we injected 18.14 kg (40 lbs) of 20% Rhodamine WT solution (3.63 kg active ingredient) into a karst window called Sweetwater Lake, which connects to a first magnitude spring, the River Rise, via a single conduit previously mapped by cave divers. Fluorescence of river water, river stage, and water elevation of three monitoring wells were monitored continuously over an 88 hour period. The monitoring wells are located 30 to approximately 890 m from the conduit. River stage was monitored 70 m downstream of the spring and converted to discharge with a well-established rating curve. Monitoring of fluorescence began approximately 16 hours prior to release of the dye and showed average background values of approximately 0.125 ppb with a standard deviation of 0.02. The initial breakthrough of dye occurred 13 hours and 58 minutes, peak dye concentration of 6.97 ppb occurred 20 hours and 2 minutes, and a return to background of approximately 0.1 ppb occurred 48 hours following injection of dye. Shape of the breakthrough curve and rapid return to background fluorescence reflect conduit flow with minimal dispersion of dye. Measured fluorescence in the monitoring wells is likely background, although an increase from 0.07 to 0.380 ppb at one well down gradient from the conduit 2 days after injection of the dye may reflect loss of dye from the conduit to the matrix porosity. Calculated dye mass return at the River Rise was 5.33 kg, which is 46% more dye than injected. This discrepancy may result from analytical errors in measurements of discharge or dye concentrations, a source of discharge in addition to the River Rise or a combination of these factors. The magnitude of the excess dye suggests dye-free water may be included in the discharge measurements. These results suggest that there is little loss of water to the matrix from this single conduit at base-flow conditions.

This study provides visible, microscopic and submicroscopic characteristics of slickenside features in two Texas Vertisols of different geomorphological age. Transport of visible anionic dye and CaBr is studied as related to soil structural surfaces, root channels and slickenside planes. Macromorphic observations were coupled with thin section microscopy, scanning electron microscopy and electron microprobe analyses. Slickenside surfaces differed from subjacent micromass of the ped interiors by stronger preferred orientation of clay particles and reduction in macropores with corresponding increase in micropores. Such characteristics could make slickensides act as semi-permeable barriers to solute transport, but this phenomenon could not be confirmed from CaBr studies herein. The majority of the solute bypass flow in both soils was conducted through root channels and ped interfaces. Slickenside surfaces in these Vertisols conducted less than 1% of the flow. It was observed primarily when the dye solution was delivered to the surface of the slickenside via the adjacent root channel. In spite of the preferential orientation of clay particles along slickenside planes, the penetration of Br into the aggregate interior was not retarded like the larger organic anion dye. These results may reflect specific moisture conditions, which should be considered in future works.

Both chemical and isotopic tracers have been previously used to constrain the variables and processes characterizing these complex systems. The Lake Logan Martin Dam site on the Coosa River, St. Clair/Talladega counties, Alabama is underlain by the Knox Group and exhibits karstic features, including near-vertical solution channels, extreme anisotropy and heterogeneity. The dam has been subject to leakage problems since its construction in the sixties and a program of monitoring and remedial grouting was implemented to decrease seepage and protect against subsidence. Numerous dye tracer studies conducted at the site have determined some preferential flow paths and recent isotopic studies have identified areas of continued leakage. This study examines the use of rare earth elements (REE) to model water source and ground/surface water interactions in karsted carbonate terrain. Ground and surface water samples have been collected seasonally (spring, summer and fall) from the Lake Logan Martin Dam site. The collected samples (11 per season) are representative of surface, well and weir locations at the dam. The samples were chemically analyzed by ICP-OES, ion chromatography and ICP-MS for major, minor, and trace constituents in addition to REE. Measured field data included pH, temperature and specific conductance. The spring season data shows a range of pH and temperature values indicative of water source. A Piper plot indicates the water samples are generally Ca (super 2+) + Mg (super 2+) , HCO (sub 3) (super -) in composition. Major element chemistry does not adequately discriminate between the water types. Plots of the shale normalized REE data show variations in patterns as well as concentrations between surface, weir and ground waters. The REE data show that the weirs, constructed to monitor leakage, are a mixture of ground and reservoir waters. Temporal trends will also be discussed.

REE have been successfully used in petrogenetic studies and interest in their use as hydrologic tracers has increased as analytical techniques have improved and become more available./ Groundwater and surface water samples were collected seasonally (spring, summer, fall and winter) from the Lake Logan Martin Dam site. Additionally, a precipitation sample was obtained. The samples were chemically analyzed by ion chromatography, ICP-OES, and ICP-MS for major, minor and trace element constituents, including the REE. Historical data (geochemical, temperature, and TDS) as well as geochemical data obtained during this study were used to distinguish between groundwater, surface water and mixed water sources. The REE patterns were found to be distinct for groundwater, surface water and mixed water samples. These patterns are seasonally consistent, showing variation only in August. The variation in REE patterns for August indicated increased mixing and correlates with increased precipitation during that timeframe. Statistical analysis of the data using principal component analysis supports the conclusion that REE are useful as indicators of water source and mixing in this system. HREE and LREE were the first two of five components describing 91% of the variation in chemical element data. In relation to sample location, three principal components reflected a similar trend observed for major element chemistry explaining most of the water samples as consisting of groundwater and recharge end members./ Typescript./ Includes bibliographical references (leaves 56-59). by Suzette A.

J. AB - Solute transport studies are increasingly being used to characterise flow mechanisms in both the field and laboratory. Realisation that solutes move preferentially through soil into groundwaters has meant that research in this area has increased in importance. The objectives of this study were to develop a method for the high-resolution examination of transport mechanisms in the laboratory, using techniques which overcame previous limitations associated with extrapolating data from soils stained with dye tracers. This paper describes a method for the collection of a large undisturbed soil column subjected to a rainfall simulation and with time domain reflectometery probes (TDR) inserted as part of a dye tracer study to examine the physical and morphological properties associated with preferential flow. A method for the acquisition of serial images to enable a high-resolution quantification of dye-stained pathways is proposed. Initial results indicated that the system provides an opportunity for detailed examination of preferential flow in two dimensions and in three dimensions through inference.

To circumvent these problems, an isolated block (3.5 by 3.5 by 3.3 m) of unsaturated fractured clayey till was used for multiple tracing experiments. The setup allowed full control of the water balance in the block. Experiments at three different steady-state flow rates were performed. Multiple tracers with different diffusion coefficients were applied in each experiment to evaluate the influence of diffusive exchange between fractures and the matrix. The tracers included two halogen anions (Cl- and Br-), two fluorobenzoic acids (FBA) (2,3-DFBA and 2,6-DFBA), two fluorescent dyes (uranine and sulforhodamine B), and one colloidal tracer (0.5-mu m latex particles). At high flow rates, the obtained tracer breakthrough showed a traditional asymmetrical behavior where a fast peak was followed by a long tailing period. At low flow rates, two of the applied tracers revealed a double peak breakthrough curve, whereas the tracer with the lowest molecular diffusion coefficient showed only one peak. The separation of the tracers was hypothesized to be influenced by extensive diffusion into stagnant areas by the tracers with the high diffusion coefficients. This was supported by the breakthrough curve obtained for the colloidal tracer, which showed earlier breakthrough and only one tracer peak.

(Energy Systems) manages a closed hazardous waste disposal unit, Chestnut Ridge Security Pits (CRSP), in the form of two trenches and several auger-holes, located on top of the eastern portion of Chestnut Ridge at the Department of Energy (DOE) Oak Ridge Y-12 Plant in Tennessee. The groundwater monitoring system for the unit presently consists of a network of upgradient and downgradient monitor wells. To investigate the discharge of groundwater to springs and streams, Energy Systems, through Geraghty and Miller, Inc., conducted an initial dye-tracer study during the driest part of 1990. The dye was detected at some of the monitoring sites, but verification was necessary due to the proximity of some sites to extraneous dye sources. Based on the results of the initial study, Energy Systems recommended to the Tennessee Department of Environment and Conservation (TDEC) in the 1990 Groundwater Quality Assessment Report (GWQAR) (HSW 1991) for the CRSP that a second dye-tracer study be conducted during the wet weather season. The procedures and materials were reviewed, and a field inspection of the monitoring sites was performed in the fall of 1991. The actual test commenced during the first week of February 1992 with a 4-week baseline monitoring period to determine the inherent variability of the emission spectra within the wavelength range characteristic of Rhodamine WT (RWT) and Fluorescent Brightener 28 (FB28) or similar naturally occuring compounds within in the aquifer. This is commonly referred as background in discussion of minimum detectable levels of dyes. On March 13, RWT and FB28 were injected; weekly monitoring began with the collection of the first set of detectors on March 19. The test was originally scheduled to conclude after 12 weeks but was extended to 18 weeks when no definitive results were obtained.

A2 - Harrison, Richard W. AB - Cave, spring, and sinkhole development in the Ozarks of south-central Missouri is placed in a geologic framework through detailed geologic mapping. Geologic mapping shows that initial dissolution and inception of cave development is concentrated just beneath sandstone beds within Upper Cambrian and Lower Ordovician dolostone. Although rocks of the Ozarks have systematic and pervasive vertical joints, the development of karst conduits is controlled by bedding planes and stratigraphic variability. In the Salem Plateau of south-central Missouri, sinkholes occur in the lower part of the Ordovician Roubidoux Formation, where sinkholes are rimmed with and contain sandstone that has collapsed into voids in the underlying Ordovician Gasconade Dolomite. Cave diving by the Ozark Cave Diving Alliance into Alley Spring, a large (average flow 3.7 m (super 3) /s) spring along the Jacks Fork in the Ozark National Scenic Riverways, shows that although the spring discharges from the middle part of the Gasconade, the source of water is a cave passage just beneath the Gunter Sandstone Member of the Gasconade Dolomite. Artesian conditions cause the upward movement of groundwater from cavernous dolostone beneath the sandstone aquitards to the large springs. We hypothesize that sandstone, which is largely impermeable due to silica cementation, acts as a confining unit where hydraulic pressure, combined with mixing of water of differing chemistry, increases dissolution in the underlying dolostone beds.

The tunnel will cross the Triassic Piora Zone, a highly weathered and fractured aquifer under high hydraulic pressure situated between crystalline rocks of the Gotthard massif and the southern Pennine nappes. We report the results of two fluorescent dye tracing tests to investigate the groundwater hydraulics associated with two losing west-flowing streams in the Piora Zone. The first dye test found the direction of groundwater flow in the aquifer to be opposite to the direction of the surface-water flow above. In contrast, dyes were detected in springs discharging in the Santa Maria Valley, located 6.5 km east of the surface water topographic water divide. A second, more thorough, dye tracing test confirmed our initial results and showed that water in the weathered Triassic Piora Aquifer moves hundreds of meters per day. The base of the aquifer is approximately 250 meters above the proposed AlpTransit tunnel which will be drilled through unweathered and unfractured dolomite/anhydrite-sequences. Our dye tracing tests, combined with the exploratory tunnel Polmengo, predict that the AlpTransit railway tunnel will be unaffected by the overlying aquifer and its complex hydraulic system.

We report here the results of two successful dye tracing tests in ground water heavily contaminated by cutting oils beneath a large inaccessible factory. The current remediation strategy includes an engineered drainage system with pumping centers to recover the oil and its derivatives. It was thought that the ground water beneath the factory flowed directly to the drainage system where oil was removed by separation from the ground water. Our dye tracing results, using uranine, sulforhodamine B, and Na-naphtionate, showed that the groundwater flow paths primarily followed the natural hydraulic gradient of a river adjacent to the site, but was also influenced by the induced hydraulic gradient towards the pumping centers. More important to the site remediation, our dye tracing tests further revealed that some contaminated ground water flow paths refract from the general gradients because the natural alluvial conditions were altered by the factory construction and infillings.

Simple systems can be interpreted analytically, but complex systems require digital (e.g. finite-difference) methods. Hydraulics, chemical kinetics, and mass balance (both hydrologic and chemical) are imposed on an idealized geologic framework. Calibration is provided by patterns and ages of known karst systems. For example, models of conduit development clearly show the relative influence of variables such as discharge, fissure width, gradient, PCO2, flow length, temperature, and mixing of flow paths. In contrast, models of existing karst aquifers are designed to predict flow and mass transport in precise spatial and temporal detail. Traditional groundwater specialists base their models on measurements in wells and (rarely) springs; but well data seldom agree with cave observations and dye traces by karst scientists, and drawdown curves seldom show evidence for nearby conduits. The two groups are measuring different parts of the aquifer: laminar flow in narrow fissures and pores vs. turbulent flow in conduits. Valid models must integrate both. Aquifer models are most sensitive to patterns of conductivity, dispersivity, and hydrologic boundaries, yet the great heterogeneity and anisotropy of karst aquifers are almost impossible to quantify, and their variability is so great that minor errors can severely compromise model validity. Digital models may reasonably predict aquifer yield in the vicinity of actual well tests, but they are weakest in predicting contaminant transport and estimating source-water protection areas. Such models must be approached with a solid conceptual framework in mind. Mathematical analysis should also be supplemented with statistical models based on field measurements, so that predictions can be stated in terms of probability.

Springs issued from the cretaceous aquifer have favoured the deepening of the reculee. As a counterpart, the aquifer drainage system had to adapt to the progressive lowering of the base level. This evolution is illustrated by the speleological network, which allow to distinguish three successive karstification phases: in the Urgonian, in the lower Barremian and then in the Hauterivian limestone. At present, only the lower Barremian of the reculee W slope and the Hauterivian are aquifers. Groundwater from these two units has different physico-chemical properties. It illustrates the partitioning of flow systems within the Cretaceous. A few tracing experiments confirmed the existence of several small independent karstic systems. Water balances calculated for the karstic springs show that most of the infiltrated water in the Barremian and Hauterivian of the syncline emerges at the Nozon springs. Hence, leakage of Cretaceous groundwater to the underlying Malm aquifer appears to be limited.

Although these dissolved gas groundwater tracers offer advantages over conventional tracers such as dissolved salts and dyes due to their innocuous nature, their utilization has been limited largely due to concerns about partitioning to trapped gas phases during transport. Dissolved gases did not behave conservatively in column or field deployments in less than saturated conditions. However, the manner in which transport was retarded was predictable and occurred primarily as a function of the Henry's Law constant of the dissolved gas tracer. When used in conjunction with a conservative tracer such as tritium (3H) the deviation from conservative behavior was used to predict the volume of unsaturated space in partially saturated porous media.

In this paper we present a method of obtaining accurate measurements in time and space using dye infiltration and image analysis. The soil color was related to the dye concentration in the soil (Cs) using 74 small calibration samples. The overall root mean square error (RMSE) was 0.057 g dm-3, however, for Cs <0.75 g dm-3, the RMSE was only 0.032 g dm-3. Variability of the concentration estimates at the pixel scale could be reduced by using an average filter. We used the calibration relationship during four infiltration experiments in a 0.95 by 0.975 m large Plexiglas Hele-Shaw cell to calculate dye concentration patterns. Using the first and second order time moments, the dispersivity was calculated for nine different artificial column widths, from 0.0014 (local-scale) to 0.72 m (meso-scale). The horizontally averaged lambda proved to be identical for column widths from 0.0014 to 0.045 m. For larger scales, lambda gradually increased. We noticed that the two experiments with higher flow (1 and 2) and the two experiments with lower flow (3 and 4) showed an almost identical variation of meso-scale lambda with depth. We concluded that above a specific critical value of theta ( approximately 0.22 m3 m-3), solute mixing is enhanced, leading to a lower lambda , and that solute transport can be described as a convective-dispersive process. When theta is lower than this critical level, part of the porosity is deactivated and mixing between individual stream tubes decreases, which implies that transport then occurs as a stochastic-convective process.

SVG allows a high measuring rate (up to one every 2 seconds), short control section length (down to 10 cm), high accuracy (+ or -1.5 cm s (super -1) ), and unbiased calculation of the mean velocity in experimental conditions with turbulent, supercritical flow. A few cubic centimetres of saturated salt solution (NaCl) are injected into the flow at regular time intervals using a programmable solenoid valve. The tracer successively passes two conductivity probes placed a short distance downstream. The transformation of the signal between the two probes is modelled as a one-dimensional diffusion wave equation. Model calibration gives an estimation of the mean velocity and the diffusion for each salt plume. Two implementations of the SVG technique are described. The first was an outdoors simulated rainfall experiment in Senegal (conductivity probes at 40 cm apart, 8 Hz measurement rate, salt injections at 10 second intervals). Mean velocity was estimated to range between 0.1 and 0.3 m s (super -1) . The second was a laboratory-based flume experiment (conductivity probes at 10 cm apart, 32 Hz, salt injections at 2 second intervals). Another SVG with probes at 34 cm apart was used for comparison. An acoustic Doppler velocimeter (ADV) was also used to give an independent assessment of velocity. Using the 10 cm salt gauge, estimated mean velocity ranged from 0.6 to 0.9 m s (super -1) with a standard deviation of 1.5 cm s (super -1) . Comparisons between ADV, 10 cm SVG and 34 cm SVG were consistent and demonstrated that the salt-tracing results were unbiased and independent of distance between probes. Most peaks were modelled with r (super 2) >90 per cent. The SVG technology offers an alternative to the dye-tracing technique, which has been severely criticized in the literature because of the wide interval of recommended values for the correction factor alpha to be applied to the timings. This article demonstrates that a fixed value of alpha is inappropriate, since the correction factor varies with velocity, diffusion and the length of the control section.

This study presents the results of MODFLOW numerical modeling in which drain cells in a finite-difference model are used as analogs for preferential flowpaths or conduits in karst environments. In this study, conduits in mixed-flow systems are simulated by assigning connected pathways of drain cells from the locations of tracer releases, sinkholes, or other karst features to outlet springs along inferred flowpaths. These paths are determined by the locations of losing stream segments, ephemeral stream beds, geophysical surveys, fracture lineaments, or other surficial characteristics, combined with the results of dye traces. The elevations of the drains at the discharge ends of the inferred flowpaths are estimated from field data and are adjusted when necessary during model calibration. To simulate flow in a free-flowing conduit, a high conductance is assigned to each drain to eliminate the need for drain-specific information that would be very difficult to obtain. Calculations were performed for a site near Hohenfels, Germany. The potentiometric surface produced by the simulations agreed well with field data. The head contours in the vicinity of the karst features behaved in a manner consistent with a flow system having both diffuse and conduit components, and the sum of the volumetric flow out of the drain cells agreed closely with spring discharges and stream flows. Because of the success of this approach, it is recommended for regional studies in which little site-specific information (e.g., location, number, size, and conductivity of fractures and conduits) is available, and general flow characteristics are desired.

This paper presents an approach to numerical modeling in which drain cells in a finite-difference model are used as analogs for preferential flowpaths or conduits in karst environments. In this study, conduits in mixed-flow systems are simulated by assigning sequences of adjacent drain cells from the locations of tracer releases, sinkholes, or other karst features to outlet springs along inferred flowpaths. These paths are determined by the locations of losing stream segments, ephemeral stream beds, fracture lineaments, other surficial characteristics, or results of geophysical surveys, combined with the results of dye traces. The elevations of the drains at the discharge ends of the inferred flowpaths are set to the elevations of discharge springs; the elevations at the beginning of the inferred flowpaths are estimated from field data and are adjusted as necessary during model calibration. To simulate a free-flowing conduit, a high conductance is assigned to each drain to promote the removal of water by modeled conduits and to eliminate the need for drain-specific information that would be very difficult to obtain. Calculations were performed for two sites: one near Hohenfels, Germany, and one near St. Louis, Missouri. The potentiometric surfaces produced by these simulations agreed well with field data. The head contours in the vicinity of the karst features behaved in a manner consistent with a flow system having both diffuse and conduit components, and the sum of the volumetric flow out of the drain cells agreed closely with spring discharges and stream flows. Because of the success of this approach, it is recommended for testing of conceptual flow models and for regional studies in which little site-specific information is available, and general flow characteristics are desired.

Five dye traces completed as part of this study were combined with results from nine traces conducted in previous investigations by Ewers and others (1995) and Jones (1990). As a result, five "major" groundwater basins were further delineated, and structural as well as lithologic influences on groundwater movement were better understood. The study area was divided into eastern and western halves by Hardy Creek. The eastern half was comprised of three major groundwater basins; Sims Spring, Batie Springs, and Flanary Bridge Spring Basins. Hardy Creek and Surgenor-Gallahan Groundwater Basins were partially delineated in the western half. Traces seem to indicate that groundwater flow occurs in both strike and dip directions and can be influenced by structural controls, bedding planes, lithologic units, high flow conditions, and secondary porosity and permeability. As a result of this study, additional questions have been raised with respect to further delineation of groundwater divides and recharge areas. Additional work is necessary to answer these questions.

Rock mines are excavated to the same depth as the well field's primary producing zone. The underlying karst Biscayne aquifer is a triple-porosity system characterized by (1) a matrix of interparticle porosity and separate vug porosity; (2) touching-vug porosity that forms preferred, stratiform passageways; and, less commonly, (3) conduit porosity formed by thin solution pipes, bedding-plane vugs, and cavernous vugs. Existing ground-water flow and particle tracking models do not provide adequate information regarding the ability of the aquifer to limit the advective movement of pathogens and other contaminants. Chemical transport and colloidal mobility properties have been delineated using conservative and microsphere-surrogate tracers for Cryptosporidium parvum. Forced-gradient tests were executed by introducing conservative tracers into injection wells located 100 m (328 ft) from a municipal-supply well. Apparent mean advective velocity between the wells is one to two orders of magnitude greater than previously measured. Touching-vug, stratiform flow zones are efficient pathways for tracer movement at the well field. The effective porosity for a continuum model between the point of injection and tracer recovery ranges from 2 to 4 percent and is an order of magnitude smaller than previously assumed. Existing well-field protection zones were established using porosity estimates based on specific yield. The effective, or kinematic, porosity of a Biscayne aquifer continuum model is lower than the total porosity, because high velocities occur along preferential flow paths that result in faster times of travel than can be represented with the ground-water flow equation. Tracer tests indicate that the relative ease of contaminant movement to municipal supply wells is much greater than previously considered. AD - U. S.

The tests were designed specifically to produce detailed, high-resolution information about the tails of the breakthrough curves typically observed in this kind of aquifer and test. A set of mutually compatible, low detection limit tracers was identified through laboratory investigations. Two tests were carried out over distances of 20 m and 40 m along each of the two radii towards an abstraction borehole where tracer concentration was monitored. Simple dual porosity models were calibrated using the data from one test on each radius.

A dye tracer test under flood conditions shows a widespread drainage system to remote springs and direct afflux to the porous aquifer of the Rhine Valley. These karstwater passages are leading through nonkarstified flysch and a marly layer. Both layers are lithologically rather impermeable and karstwater passages through these layers indicates water leading fault zones. Properties of the drainage patterns strongly depend on the hydrological situation.

These islands are part of the Alexander Terrane geologic province, accreted to the western North American craton during Jurassic to early Tertiary time (Gehrels and Berg, 1992; 1994). Silurian turbidites, carbonates, and conglomerate are the most widespread geologic units on these islands, the Heceta Limestone being the dominant bedrock type. The potential for karst development within the Heceta Limestone is exceptional. Factors favoring this include high precipitation rates, calcium carbonate purity, strong structural fabric, and highly acidic surface waters from muskegs (Baichtal and Swanson, 1996). Repeated glaciation has significantly altered SE Alaska karst systems by eroding surface topography, covering large areas with compact till and adding to subsurface systems. Extensive past timber harvesting has also affected the karst hydrology. Dye trace studies were conducted on the Heceta Limestone of Kosciusko and Tuxekan to assess karst hydrology. The work on Kosciusko was designed to assess hydrologic connectivity, storage capacity, flow rates, and karst system recharge from major island streams in specific areas. On Tuxekan, the objectives of this study were primarily to establish flow paths through the karst system. Study results indicate both islands are underlain by a complex karst hydrologic system. Nearly every dye injection was recovered at one or more sampling point. Straight-line travel times indicate that movement of karst waters through the subsurface system is very rapid (up to 6,500 ft/day). Overlays of dye trace paths with mapped geology suggest that some dye paths can be explained by flow through large structural features and along geologic contacts. This was more evident on Tuxekan Island, where the majority of dye sampling points were at resurgences versus streams. Other dye paths follow more complicated paths that cannot be easily explained by dominant geologic features, at times crossing beneath topographic highs and/or dyes were detected in multiple, distal locations. Such passageways are likely to have developed through more diffuse fractures and weaknesses within the limestone. These studies demonstrate the importance of dye tracing demonstrate to understanding karst hydrology.

Results of the tracer tests will help calibrate flow models of the Edwards, design an improved ambient water quality monitoring program, and improve response to hazardous material spills. Comal Springs, the largest in the southwestern United States with an average discharge of 8.5 m3/s, emerge from hundreds of individual locations and form the 1.2 km long Landa Lake in New Braunfels, Texas. The Comal Springs "complex" is located on the 250 m displacement Comal Springs Fault, which juxtaposes the recharge and deep artesian zones of the Edwards Aquifer. Over 80 participants, representing four countries and more than 15 public and private entities monitored thirty surface sites and three municipal wells, and collected and analyzed over 1,600 water samples. A trace from the 200 m deep flowing artesian well (with a head about 15 feet above ground level) yielded flow velocities of 290 m/d to springs 350-750 m away, and demonstrated conduit flow in the deep artesian zone. The dye emerged from rise points in a 400 m stretch of the middle of Landa Lake as described by Martel's (1896) "underground delta" model. Dye was also detected in a municipal well 300 m from the dye injection point. A second dye, simultaneously injected into a 25 m deep well on the up thrown side of the fault, moved at 1400 m/d to a separate set of rise points at the springs.

Fluorescent tracing agents that have been approved by the U.S. Food and Drug Administration for use in drugs and cosmetics, offer a powerful tool for resource managers charged with protecting public water supply systems and endangered species critical habitats. Four of these dyes: uranine, eosine, pyranine, and Phloxine B have very low detection limits (<0,1 ppb), low analytical cost, and low sorption. A fifth dye, erythrosine, is available but is only weakly fluorescent and may not be quite so useful Properly designed quantitative tracer tests, using fluorescent dyes provide the maximum information about contaminant flow paths, accurate time of travel, peak concentration, duration of passage of the tracer and estimates of hydraulic parameters. Such data yield valuable insights into management strategies to monitor and remediate contaminants. Tracers can also be used to empirically test flow path and time of travel estimates derived from other techniques of source water protection delineation such as ground-water models, arbitrary fixed radii, hydrologic boundaries, and "rule of thumb" estimates. Quantitative tracing done with fluorescent dyes has firmly established a relationship between amount of tracer injected and peak concentration at the discharge point of concern. This relationship may also allow a reasonably accurate estimation of the concentration of contaminants from a hazardous materials release. These equations have been used with success to determine potential impacts on springs from a PCE/TCE--contaminated site in Nashville, Tennessee and from a leaking storage tank in New Braunfels, Texas. This method has also been used to successfully calculate the volume of dyes for tracing to public water supplies or critical surface water habitat.

Furthermore, it enables the estimation of the risk to groundwater by pollutants, and the visualisation and classification of flux patterns. A stochastic model is presented that allows for the modelling of a wide range of flow patterns in soils as they appear in dye tracer experiments. The leading idea is that infiltrating water runs along paths, not necessarily preferential ones, and water spreads into the soil uniformly from the paths into the matrix. The model is essentially based on a Poisson point process and three independent random fields. The point process defines the starting points of the paths at the surface. The values of two random fields determine the course of the paths. The third random field governs the depth of the infiltration front. As an extension of the model, we present two simulated examples for stratified soils.

This report documents the Cy 2001 well inspection events and their subsequent well maintenance requests. Well inspections are performed in order to assess the condition of the monitoring well and any subsequent maintenance needs. Inspections help to ensure that the collection of groundwater samples, and/or hydrologic measurements, are representative of the subsurface and not an artifact of changing downhole conditions. Inspections and maintenance contribute to the effective longevity of each well. Currently, the Y-12 Groundwater Protection Program (GWPP) inspects wells on an annual or triennial basis depending on the status of the well as follows: (1) the well is under the GWPP annual water quality sampling program (active wells); (2) wells where hydrological monitoring (e.g., semi-annual water level measurements, long term water level monitoring, slug test, pumping test, dye tracer test, etc.) is in progress (active or inactive wells); or (3) wells that are not in service (inactive wells), but are not currently scheduled for plugging and abandonment.

Located on karst terrain, this perennial spring flows from a small cave and provides one of the few reliable water sources in the area. The spring is a now an important interpretive feature and visitor attraction at Abraham Lincoln National Historical Site, which commemorates Lincoln's birthplace. In 1996, the authors began studying Sinking Spring and water quality/land use interactions to assist park managers of the historic site to better focus their efforts on areas of concern which may effect the spring. In the first phase, they delineated the recharge area and flow system using fluorescent dye tracing, cave survey, and unit base flow discharge analysis. Using Geographic Information Systems (GIS), they also mapped land use within the identified source areas. An aerial photography fly over allowed development of a one-foot contour interval topographic map of the spring area. The GIS constructed from this topographic information was used to study flooding mechanisms within the sinkhole surrounding Sinking Spring. Field measurements showed that the spring's catchment area was primarily within the 45-hectare park, along with adjacent agricultural land. Two unsuccessful die traces indicate that drainage from Highway 31E, which bi-sects the historic site, doesn't flow to the spring. Floodwaters that occasionally fill the large sink appear to result from subsurface hydraulic damming from the South Fork Nolin River. Storm pulse sampling to quantify spring water quality is underway--a rainfall event during June 2001 was sampled with one-hour resolution. Overall, water quality is considered fair for karst flow draining agricultural land. The most significant impacts were from fecal coliform bacteria (maximum result: 2,000+ colonies/100 mL) and the broadleaf herbicide Trifluralin (maximum concentration result: 25 microg/L). No other chemicals of concern, including 11 other tested pesticides, were identified.

Two dye tracing experiments have proved the link with hotsprings in Val d'Illiez, 9 km to the NW. The temperature increase is due to the depth the water reaches before coming up, following an alpine inverse fault.

A2 - D'Annibale, Paul A2 - Williams, Frank AB - The Bogardus Spring system in northeastern Schoharie County, NY has three point inputs from sinking streams at Turbine Cave, Loden's Sink and Schanz Sink. Quantitative dye tracing experiments using Uranine and Rhodamine dyes prove all three connections between insurgences and the spring. Tracing tests were carried out using automated water samplers working at intervals of fifteen minutes for periods up to about eight days. Monitoring of weirs installed at the insurgences and the spring provides data on surface input and spring flow. Tracing experiments were carried out at spring flows ranging from about 70 l/sec to about 800 l/sec. Nearly complete "elution" curves were obtained for the tests. Dye was also injected into a surface stream into which Bogardus Spring discharges. Dye transit times decrease with increased spring flow, approximately linearly on a log-log plot. At a given flow, the average flow velocity appears to increase slightly with distance between insurgence and spring. The flow path from Loden's Sink, which is intermediate in distance from the spring compared to the other two insurgences, appears to be less efficient than the others, as evidenced by delays in dye arrivals, especially as measured at peak dye concentrations. At very low flows the dye arrival from Loden's Sink shows a series of peaks rather than a smooth curve. At most flows the Loden's sink curves are broader than for traces from the other locations. Loden's Sink is at the bottom of a large (ca. 10 (super 6) liter) sinkhole that fills completely at the highest flow for which we have data. Under the conditions of our tests this led to a double peak from Loden's, probably due to draining of the dyed water stored in the sinkhole pond after flow contributions at the spring from the other insurgences had dropped. Dye travel time is expected to decrease at higher spring flows for simple channel flow, as is observed. The tracing results from Loden's Sink may be explainable in terms of differences in the details of the flow path between Loden's and Bogardus Spring as compared to the other two insurgences, including the obvious sinkhole pond that forms at high flows. Some of these details (or complexities) may often be hidden in karst drainages and contribute to complex behavior of these flow systems.

A series of experiments were performed using a device designed specifically to fit into a 152.4 mm (6 inch) diameter well casing. A test apparatus was assembled of polyvinyl chloride (PVC) pipes using porous stones to simulate groundwater flow conditions in an aquifer. The measurement device released fluorescein dye into the center of the simulated well using a dye release mechanism consisting of a glass vial with a salt plug suspended in modeling clay at its base. A small hole in exposed the top and bottom of the salt plug allowed the exchange of dye with the groundwater flowing past the dye outlet hole. The dye released into the well was subsequently adsorbed onto the surface of carbon rods located at eight equally spaced points around the perimeter of the well. The relative amount of the fluorescein dye remaining in the dye release vial, as well as the amount adsorbed on the carbon rods, was measured by the intensity of fluorescence detected by a fluorometer. The amount of the dye adsorbed onto the rods was shown to indicate the direction of groundwater flow with low directional dispersion. Groundwater flow velocity measurements were attempted using two methods. The first method correlated the fluorometer reading for the fluorescein dye/groundwater mixture remaining in the vial after a measured period of time with the flow velocity. The second method correlated the root-mean-square of the fluorometer readings for the fluorescein dye adsorbed onto and extracted from the carbon rods for an individual experiment with the groundwater flow velocity. The results of the first method's groundwater flow velocity experiments were a set of linear equations based on a multiple linear regression analysis relating discharge, measurement time, and fluorometer readings. The second method resulted in a linear relationship between the groundwater flow velocity and the root-mean-square of the carbon rod adsorption data. However, the groundwater flow velocity analysis using both methods showed poor correlation coefficients for the derived linear relationships. The suspect groundwater velocity measurements were attributed to the inconsistent nature of the dye release process and the inherent problems of introducing a dye tracer into a low Reynolds number laminar flow environment.

These methods, however, generally assume that the aquifers in these terranes behave as porous media at the scale of the study area. Fractured-rock aquifers that do not behave as porous media, such as those in carbonate (karst) terranes, generally cannot be studied with the same methods used to characterize porous-media aquifers. In these settings, delineation of source-protection areas or zones of contribution for wells and particularly springs, often can be done only by integration of hydrogeologic mapping techniques such as water-level measurements, discharge balancing, and dye-tracer tests. Dye tracing has proven to be one of the most effective methods for determining zones of contribution, general directions of ground-water flow, and residence times for water in karst aquifers where nonporous-media (conduit) flow predominates. Source-protection areas and time-of-travel zones delineated for a karst spring and two wells discharging from carbonate rocks in the Bear River Range of northern Utah were compared to results of dye tracing. Results of five tracer tests indicate that time of travel based on porous-media concepts can be substantially overestimated in terranes where conduit flow paths are present. Maximum ground-water travel times ranging from 8 to almost 31 days were determined for losing stream reaches 3.0 to 7.2 miles upgradient from Dewitt Spring and within the delineated source-protection areas. These travel times indicate that average ground-water velocities ranged from about 530 to almost 2,000 feet per day. Because passive dye-tracing methods were used, however, ground-water travel times are probably substantially shorter and velocities are greater. Results of dye tracing also show that a large part of the source-protection area delineated for the wells probably lies within the recharge area for the spring. In addition, source-protection areas in these terranes may be under or overestimated when surface-water divides are assumed to be ground-water divides. As a result, dye tracing can be used to help delineate areas that do not contribute to springs or wells, and thus, minimize the area that is necessary for source-protection management. AD - U. S.

These limestones and dolomites contain the principal aquifer in the Logan Canyon area and make up the upper part of the Logan Peak Syncline, a large structure that influences ground-water movement in much of the region. All of the carbonate units are capable of transmitting water along dissolution-enhanced fractures, faults, and bedding planes. Recharge to the carbonate aquifer takes place through discrete points (sinkholes), as stream seepage through fluvioglacial deposits, and as infiltration through soils on ridges and valley slopes. Water entering sinkholes and pits moves vertically downward along solution-enlarged fractures to conduits that channel water to large springs. Precipitation that infiltrates directly probably moves along diffuse pathways through the rock matrix toward conduits and can be a substantial component of long-term storage in the aquifer and base flow of springs. Discharge from the carbonate aquifer is primarily from large springs along the Logan River, with flow variability from less than 1 to at least 75 cubic feet per second. Spring discharge responds primarily to snowmelt runoff, with peak flow from late spring to early summer diminishing to base flow during the winter months. On the basis of dye tracing and discharge, recharge areas for the major springs are estimated to be between 5 and 15 square miles and as much as 3,300 feet higher than the springs. Recharge area delineations also indicate that surface-water drainage basins do not coincide with ground-water basins. Maximum ground-water travel times to the springs were 8 to 31 days from losing streams as far as 7 miles away. Temperature and specific conductance of water from the major springs are inversely related to discharge. During peak flow, specific conductance of water typically ranges from 250 to 290 microsiemens per centimeter (mu S/cm) at 25 degrees Celsius ( degrees C) and temperature ranges from 5.5 to 6.0 degrees C. Conversely, during periods of base flow, specific conductance ranges from 340 to 420 mu S/cm and temperature ranges from 6.5 to 8.0 degrees C. The range of measured values results from mixing of recharge derived from snowmelt with ground water that has had a longer residence time. AD - U. S.

Over the course of two winters (2000-2001 and 2001-2002) we excavated vertical soil profiles during snowmelt to examine the distribution of a dye tracer (Brilliant Blue FCF) that had been applied on the surface of a 7-m (super 2) plot at the beginning of the winter. Soil conditions varied between the winters, with the soils remaining unfrozen during the first and a significant frozen layer forming during the second. With this method the dominant infiltration processes at these 2 sites were identified. During the first winter the water infiltration at Hannigalp showed a pronounced preferential behavior, whereas at Gd St Bernard we found a more homogeneous front-like infiltration. During the second winter the impeding impact of the frozen soil was clearly seen at the Hannigalp site--however, only in the first stage of the snowmelt. More decisive for the formation of lateral surface runoff was the buildup of an ice layer on the soil surface due to melting and refreezing. Cold-chamber experiments, in which intact soil columns were irrigated with a dye tracer and a fluorescent tracer solution, confirmed our in situ observations with regard to heterogeneity and soil frost effect on the infiltration pattern. Our study showed that both tracers can be applied to frozen soil in the laboratory, whereas at the remote alpine locations only the dye tracer method was applicable.

We report on a tracer experiment carried out on a 7.3X20 m (super 2) plot on a loamy grassland soil to determine the flow paths to a tile drain at 1 m depth. The experiment consisted of a series of consecutive tracer applications including seven solutes and liquid manure that were applied either on the entire plot or on limited bands. Based on the discharge behavior under natural conditions, we estimated the effective hydraulic conductivity of the subsoil to be in the order of 8-29 cm day (super -1) . Under experimental conditions, the soil transmitted 120 mm day (super -1) into the subsurface drain and two vertical profiles without producing surface runoff. Only part of the soil water, corresponding to 6-27 mm of the soil depth, contributed to the fast hydrological response. The transport of the tracers was very fast. Within 7-16 h after application of the conservative Br (super -) , Cl (super -) and HDO and the slightly sorbing substances brilliant blue (BB) and amino-G-acid (AG), these tracers reached relative concentrations in the outflow between 19% and 35% of the input concentrations. From the mass balance for water and solutes, it follows that the tracers were quickly transported over lateral distances of several meters. The manure constituents dissolved reactive P (DRP), NH (sub 4) (super +) and Cl (super -) , applied as liquid manure on the surface on a 1 m wide band above the tile drain, reached the drain within 5 min after application. After the early peak of DRP and NH (sub 4) (super +) , their concentration in the drain decreased quickly to background levels, whereas Cl (super -) exhibited a second peak. Despite the fast transport and the small soil volume conducting water and solutes, the interaction between irrigation water and soil matrix was intimate enough to retain the two sorbing tracers. From the stained flow paths, the hydrologic behavior of the field under natural conditions and the hydrometric data during the experiment, it follows that the fast lateral tracer transport occurred mainly close to soil surface and not through the subsoil. Only in the immediate vicinity of the tile drain and of two lateral pits at the edge of the experimental plot water was redirected downwards and discharged from the tile drain and the bottom parts of the profiles, respectively. Hence, effluent from tile drains may not be representative for water reaching the subsoil or shallow ground water in undisturbed soils.

The piezometer intake zones were about 2 m (Tests 1 and 2) and 18 m below static water level, and the pumping borehole was sealed using a packer at about 11 m (Tests 1 and 2) and 19 m below static water level. Analytical expressions were used to interpret the data. Test 2 was unsuccessful. Four pathways were discernible from the Test 1 tracer breakthrough curves. These pathways were interpreted as being due to three dominantly fracture routes and one dominantly intergranular flow route. The earliest (sharp) peak arrived after a few hours, and the last (broad) intergranular flow peak arrived after around 40 hours. Fluorescein was delayed slightly (retardation factor = 1.4) relative to the other tracers. In the deeper Test 3, three pathways were discernible, with concentration peaks at about 9, 25, and 78 hours. Fluorescein was delayed relative to amino-G-acid (retardation factors = 1.25 and 1.5) in the second and third pathways. As with the first test, the last peak was very broad, suggesting a variety of intergranular routes through the rock, and possibly the effect of diffusion. The tests clearly demonstrate the importance and complexity of fracture flow over short distances in the Triassic sandstones, the complexity of the intergranular flow routes, and that different retardation factors can be associated with different pathways.

In groundwater remediation, characterizing the flow paths and velocity is a major objective. Various tracers have been used for measuring groundwater velocity and transport of contaminants, colloidal particles, and bacteria and nutrients. The conventional techniques use dissolved solutes, dyes. and gases to estimate subsurface transport pathways. These tracers can provide information on transport and diffusion into the matrix, but their estimates for groundwater flow through fractured regions are very conservative. Also, they do not have the same transport characteristics as bacteria and suspended colloid tracers, both of which must be characterized for effective in-place remediation. Bioremediation requires understanding bacterial transport and nutrient distribution throughout the acquifer, knowledge of contaminants s mobile colloidal particles is just essential.

The environmental tracing allowed the separation of the flood hydrograph and the identification of the general hydrological processes at catchment scale. The dye tracing experiment was conducted in order to study the soil water behaviour during a rainfall-runoff event at hillslope scale. The principal aims of the dye tracing were: to study the soil water response to a rainfall-runoff event; to test a new fluorimeter which directly determines dye tracers concentrations in the field and to compare these measurements with those in the laboratory; to study the dye behaviour in the soil. The dye tracing experiment confirms the results of the environmental tracing showing the important contribution of the soil water to the floods and it furnishes valuable and complementary information concerning soil water flow.

The complex drains a small, forested surface catchment protected by the park and thus offers relatively pristine conditions to study the background geochemistry of the aquifer. As part of this work we are mapping out the conduit flow system feeding the shafts using fluorescent dyes. Understanding this flow system is a prerequisite to detailed geochemical studies, and offers an interesting challenge: the known conduits are all too small for human exploration, and so the traditional methods of cave survey used so extensively elsewhere in the cave are of little use. Five dye injections were conducted during wet conditions in spring 2000. After testing for the absence of background contamination, 25 mL each of Rhodamine WT and fluorescein dyes were injected into two sinking surface streams (the "Eastern" and "Western" branches of an unnamed ephemeral stream) above the shaft area in February. The waters of six separate shafts (Hawkins's Spring, the "Water Clock", and Edna's, Nelson's, Einbigler's, and Cathedral Domes) were monitored with charcoal dye receptors, which were replaced and analyzed by elution and spectrofluorophotometry over the next 67 days. The five shafts closest to Edna's Dome were all positive for fluorescein within nine days, and no dye was detected at Cathedral Domes. No Rhodamine was detected, so larger amounts of were injected into the Eastern Branch in early and late March and were detected at three of the shafts, including the most distant at Cathedral Domes. A third dye, eosine, was injected in late March at different sinkpoint nearby and was detected within a week at a different trio of shafts with some overlap between the other traces. Results show that the flow paths consist of steep, vertically bifurcating conduits between a single surface input and multiple shafts within the cave. These are also overlapping networks, in that a single shaft can receive flow from more than one surface input. While shafts are known to occur commonly in groups (complexes), the bifurcating flow identified here may provide an explanation for this clustering.

The contribution of these components to water along the flow path and at discharge points is difficult to determine, but has implications for travel times and contaminant concentrations. We monitored a spring discharging from an enlarged fracture into Bushkill Creek in SE PA and a well 350 m upgradient that intersected a 1 m wide conduit. Samples were collected monthly for 17 months, and loggers monitored temperature, stage, and conductivity at both locations for 9 months. In addition, a non-quantitative dye trace was performed by injecting dye into the well and monitoring 9 springs in the discharge area using charcoal packs. The dye trace showed a connection between the well and springs. However, the dye was visible in the well for about 3 months and only appeared in dilute concentrations at the springs after a large precipitation event also at 3 months. The dye was distributed along a 50 m stretch, indicating the connection between the well and the creek is a series of networked fractures and conduits rather than a single large conduit. This suggests a diffuse flow path from the well to the springs. Water level in the well typically peaked about half a day after the spring and recovered more slowly from precipitation events. Temperature was constant in the well, but varied in the spring with storm events. Constant temperature is evidence for longer flow paths, while variable temperature suggests shorter flow paths. Conductivity, Ca, and HCO3 were higher in the well, but also showed more variability. For example, HCO3 averaged 400 mg/L in the well, with a standard deviation of 85 mg/L, while the spring averaged 170 mg/L with a standard deviation of 40 mg/L. The PCO2 and the SI of calcite in the well were generally higher, although both the spring and the well were undersaturated except for several well samples in June and July of the second year. There is an apparent paradox in that the well has higher conductivity and slower water level recovery but more ion variability. The paradox is explained by a longer residence time for the water in the well, but with periodic flushing by more dilute water. The spring has a more constant mix of matrix and conduit water, suggesting diffuse recharge but shorter flow paths occur in this spring.

The dam, designed as a rock-fill dam with a height of 77 m, is already used for irrigation. The foundation consists of Mesozoic ophiolite, Paleocene allochthonous units composed of different lithologies, and Miocene conglomerate. The conglomerate lies unconformably on the other units. Quaternary basaltic lava patchily covers the others. Seepage from upstream to downstream occurs through the allochthonous karstic limestone. This limestone, which is overlain by conglomerates, has a thickness increasing towards the right abutment. To prevent seepage at the right abutment, a 200-m long and 60-m deep grout curtain along the dam axis was constructed. After the impoundment, some springs occurred downstream, and for this reason, extra grouting was performed. However, the seepage problem could not be solved. In order to determine the seepage direction and karstification pattern, hydrological studies have been done. Additional investigation boreholes have been drilled to observe fluctuations of the groundwater level and to analyze hydrochemistry. Also, dye tracer tests have been carried out. As a result of these hydrogeological studies, seepage paths were observed in the karstic limestone located between the dam and the spillway. As those carbonate rocks continue beneath the spillway, the seepage problems are enjected to continue.

While the skills taught at traditional geology field camp are still relevant and useful, geologists working in the environmental field also require other field skills. Northern Illinois University and Illinois State University have collaborated to create a camp that teaches aspects of a traditional field camp, a hydrogeology field camp, and topics unique to an environmental field camp. This new four week long field camp draws on the expertise, equipment, and facilities of both universities. Exercises were designed so that the students are directly involved with data collection in the field, data reduction, and data interpretation in the computer lab. A strong emphasis was placed on quantitative aspects of data interpretation and the use of software to manipulate and display the field data. The first half of the camp focused on measuring and monitoring water on and beneath the land surface. Activities included aquifer and slug tests, infiltration tests, a stream dye tracer test, stream flow measurements, organic and inorganic water sampling techniques, and field measurement of water quality parameters. The second half of the camp covered Quaternary stratigraphy and soils, drilling techniques, and shallow geophysical techniques. The Quaternary and soils section included field trips to familiarize the students with the regional geologic units and landforms. The final project for this section was mapping the surficial geology of a 7.5 minute quadrangle based on topography and drilling and analysis shallow cores. Drilling exercises included demonstration of the hollow stem augur and rotary methods and well installation. Students logged borehole geology and compared it to borehole resistivity. Techniques covered in the geophysics section included resistivity, conductivity, magnetics, and seismic refraction. The geophysical techniques were used to identify karst features, the water table, and buried anthropogenic features. Exercises not normally associated with geology field camps included a survey of benthic organisms in a stream, use of diatoms as recorders of water chemistry, and forest ecology. Overall, we believe that the students gained first hand knowledge of all of the major skills that a practicing environmental geologist uses today.

Downward mobilization of DNAPL, up gradient along an overriding cosolvent front, was observed. This produced significant pooling above a fine-grain layer that in some cases lead to entry into the capillary barrier beneath. Entry pressure calculations using physical and hydrogeologic parameters provided an excellent prediction of breakthrough of DNAPL into the capillary barrier. Calculations predict approximately 0.5 m of DNAPL would be necessary to enter a Beit Netofa clay, under extreme cosolvent flooding conditions (100% ethanol). Gradient injection of cosolvent did not appear to provide any benefit suggesting a rapid decrease in interfacial tension (IFT) compared to the rate of DNAPL solubilization. Use of a partitioning alcohol (tertiary butyl alcohol, TBA) resulted in DNAPL swelling and reduced entry into the capillary barrier. However, the trapping of flushing solution, containing PCE, could potentially lead to longer remediation times. AD - U. S.

Breakthrough curves (BTCs) of Cl- and two adsorbing fluorescent dye tracers, brilliant sulfaflavine (BF; 1H-Benz(de)isoquinoline-5-sulfonic acid, 2,3-dihydro-6-amino-1,3-dioxo-2-(p-tolyl)-, monosodium salt) and sulforhodamine B (SB; xanthylium, 3,6-bis(diethylamino)-9-(2,4-disulfophenyl)-, inner salt, sodium salt), were measured. Three cores were scanned with x-rays to determine the three-dimensional (3-D) structure of large pores. After the leaching experiment, soil cores were horizontally sliced and dye concentration distributions on cross sections were derived from fluorescence signal images. Transport was investigated using BTCs and concentration maps, adsorption isotherms, and predictions by three different transport models: convection dispersion model (CDM), stream tube model (STM) and physical nonequilibrium model (PNEM). The dense network of large pores in the two upper soil layers induced a uniform lateral spreading of dyes and the CDM described the transport fairly well. In cores from the deeper layer, the large pore network was considerably less dense and dye patterns followed closely the few large pores without lateral mixing indicating preferential flow and explaining the fast dye breakthrough. Predictions by the STM revealed that the fast SB breakthrough could not be explained solely by preferential flow. Fitting the PNEM to breakthrough data and the low total dye concentration in the preferential flow region suggested a small sorption capacity of the preferential flow region for SB. Therefore, preferential leaching of dyes resulted from small-scale variations in physical and chemical soil properties.

Folded, faulted, and fractured Cambrian and Ordovician carbonate and siliciclastic rocks underlie the LSC. The LSC's primary mission is to provide and interpret data on the health and habits of aquatic species. The Center's work requires large quantities of water and most of the water comes from highly productive karst limestone springs located on the facility. These springs supply adequate water during normal to wet climatic conditions, however the availability of water during dry conditions is not well known. The USGS has conducted geologic mapping, karst mapping, audio-magnetotelluric soundings, and down-hole geophysical measurements in the area encompassing the LSC. These data improve our understanding of the geologic structure and the role of fractures, faults, joints, and bedding planes in controlling ground water flow. Comprehensive analysis of the ground-water resource by the USGS includes: installation of monitoring wells, assessment of current and past land-use, water-level monitoring, long-term drawdown tests of the backup supply wells for the LSC, and dye-tracer tests. Future ground water flow modeling for the LSC will yield a budget of available ground-water and an assessment of current and future water demands at the Center. Results of the modeling will test pumping scenarios to minimize impacts to the springs at the facility if the two standby wells or new monitoring wells are tapped as an additional source of water for the Center. Preliminary results show that high yielding wells and springs are coincident with the troughs of synclinal features and fault zones. Wells drilled within synclines produced as much as 300 gal/min while wells on anticlines produced lesser amounts averaging about 18 gal/min. Wells drilled on faults also yielded in excess of 300 gal/min. Springs on the facility are associated with both thrust faults and cross-strike faults. Techniques and models derived from this study will be transferable to Future studies in areas with similar geology and ground-water issues will benefit from techniques and models derived from this study.

The major flow processes controlling macropore flow are the initiation of macropore flow (water supply into macropores) and the water transfer from the macropores into the surrounding soil matrix (interaction). The water movement during infiltration and the resulting flow paths were studied with combined sprinkling and dye tracer experiments under different rainfall intensities and initial soil moisture conditions. The dye tracer was continuously applied with the sprinkling water on 1 m (super 2) plots. After the sprinkling, horizontal and vertical soil sections were prepared for surveying dye patterns, which showed the cumulated flow pathways in the soils. These experiments were carried out on four hillslope sites covered with grassland, where earthworms mainly built the macropore system. The evaluation of the flow processes in the soil was based on classified dye patterns and measurements of water content and matric potential. The results illustrate how flow in earthworm channels influences general hydrological flow processes during extreme rainfall events. Macropore flow was initiated from the soil surface or from a saturated or partially saturated soil layer. Transfer of water from the macropores into the soil matrix was mainly influenced by the soil properties and soil water content. The permeability of the underlying bedrock in combination with this transfer of water controlled the drainage of the macropores. Finally, major effects of macropore flow processes on the hydrological response were extracted. Infiltration excess overland flow was reduced if water bypassed the less permeable layer through macropores, saturation excess overland flow was less affected by macropores, and subsurface flow was activated very rapidly because the infiltrated water bypassed the soil matrix. This study highlights the most important processes that have to be considered in order to understand better and to model infiltration in natural soils in the future.

Karst aquifers generally display matrix, fracture, and conduit permeability with contrasts in effective hydraulic conductivity of many orders of magnitude. Dispersed recharge into the matrix and fracture permeability provides most of the storage and a slow-response flow system, while point recharge into the conduit system provides quick flow and little storage. A current question is how to describe these components of permeability and the interchange of groundwater between them. Groundwater basins can be delineated by tracer studies and geologic boundary conditions. Progress is being made on the quantitative, fluid mechanics description of conduit flow. The evolution of karst aquifers is a mainly chemical process, with some transport of insoluble clastics by high-velocity conduit waters. The equilibrium carbonate chemistry has been well established for a long time, including accurate values for equilibrium constants. Conduits, shafts, and solutionally modified fractures are the result of differential dissolution rates. Geochemically satisfactory descriptions of dissolution kinetics have been established, so that the evolution of karst aquifers through time can be accurately described. Overall, a comprehensive model for karst aquifer behavior seems to be within sight.

The subsurface fate of these bacteria is poorly understood. To understand the transport and storage mechanism of E. coli in a mantled-karst environment, four tracers were injected during spring 2001 in Savoy Experimental Watershed (SEW), Arkansas, including rhodamine dye, chloride, E. coli and lanthanum-labeled clay. The labeled-clay tracer is considered representative of finer aquifer sediments and it was proposed that E. coli would be associated with the clays during transport and storage. Primary discharge from the basin is two springs (located 500 meters from injection point) that were instrumented for continuous discharge allowing determination of tracer load and calculation of percent capture. In April, dye and chloride were injected to assess travel times and required tracer concentrations. These tracers arrived approximately twelve hours after injection and peak concentrations occurred approximately nineteen hours after injection. Percent recovery of dye and chloride during a three-day period was 30% and 60%, respectively. A second injection in May, included dye, E. coli, and lanthanum-labeled clay. These tracers were injected during extremely low-flow conditions allowing the E. coli and clay to settle out of suspension within the aquifer, while the more conservative dye moved through as a continuous plume. The dye arrived approximately nineteen hours after injection and peak concentration occurred approximately at twenty-seven hours. Twenty percent of the dye was captured during the first three days of sampling, while only 1% of the clay was captured. Dye captured during the second tracer test was lower because spring discharge was 12% lower. Six days after injection a storm pulse mobilized the bacteria and clay tracer, resulting in an additional 60% capture for the labeled-clay. During the storm pulse, peak concentrations of the clay tracer were coincident with peak concentrations of E. coli, suggesting that ground-water storage and transport mechanisms are similar for bacteria and clay.

It is situated on the south flank of the Nashville Dome where geologic structure is usually assumed to consist of gently southward dipping beds of Mississippian-age carbonates overlying the Chattanooga Shale. Five distinct hydrogeologic regimes have been identified, and a generalized network of subsurface conduits is inferred from a structural-stratigraphic model. Recently the Army completed nearly 50 km of reflection seismic surveys, nine dye traces, and 32 deep coreholes, documenting significantly more complex structure than previously imagined, with block faulting superimposed on the regional dip. Faulting apparently played a significant role in development of shallow karst aquifers, as shown by dye tracing, and may also have facilitated deep karst development. Drilling revealed transmissive solutional voids up 6 cm thick below the Tennessee River baselevel in the lower Tuscumbia limestone and Fort Payne formations. These strata host natural hydrocarbons that are probably related to block faulting. Groundwater in deep strata are rich in Na-SO4, grading into Na-Cl water downward toward the Chattanooga Shale. Pyrite and gypsum infilling in deep cores, H2S and methane at depth, and the distinct water chemistries may suggest a hypogenic origin for the deep karst development. The faulting may be responsible for the juxtaposition of all of these conditions, and for the karst and caves as well. AD - Shaw Environmental, Knoxville, TN, United States AU - Zondlo, Thomas F.

It is the main discharge of an aquifer comprised of the Mississipian limestones belonging to Ste. Genevieve and St. Louis Formation. Previous dye tracing studies defined a 112 km (super 2) watershed situated north of the spring. Large conduits have developed in the carbonate aquifer due to dissolution processes that create a myriad of sinkholes characterizing the Mitchell Plain. Such karst structures determine turbulent flow after intense rain events from the recharge area to the spring. Orangeville Rise was monitored before and during an intense storm event (20mm of rain in 2 hours) which occurred on the 10th of November 2002. The discharge increased almost immediately and reached its maximum on the hydrograph (from less than 1 to 6 m (super 3) /s) in 24 hours. Stable isotopes (oxygen-18, deuterium and carbon-13) and major ions were used to track three different water sources (rainwater, epikarst and phreatic water). Applying linear mixing models to the chemistry of the spring water, the hydrograph separation technique allowed us to quantify contribution percentages to the total discharge. Fresh rain water entering the system supplies about 40% of the spring discharge throughout the entire storm event. Moreover timing the peak arrival of different contributions, we were able to define the circulation within the aquifer and to identify shallow and deep flow systems. Using deuterium as a conservative tracer to track rainwater, the hydrograph separation shows that the rain water produced an initial piston effect on the groundwater or on the vadose water present in the shallow subsurface. The arrival of the highest rain contribution (>50%) occurred when the total discharge approached to pre-storm values.
