Users and water-resources managers and developers are concerned about the quality of water in the aquifer. The water quality of a large part of the Upper Floridan aquifer in the Valdosta area is affected by direct recharge of water from the Withlacoochee River to the aquifer through sinkholes in the river channel north of Valdosta. Furthermore, because the Withlacoochee River receives little filtration as it recharges the aquifer in this area, ground water might be vulnerable to contamination as a result of human activities within the Withlacoochee River basin. Stream-discharge and water-quality data from 17 surface-water sites and ground-water-quality dam from 111 wells in the vicinity of Valdosta, Ga., are presented for the period 1961-93. Also, ground- water-level data for the Upper Floridan aquifer in the Valdosta area are presented in a series of potentiometric-surface maps.

Nitrite plus nitrate (as nitrogen; hereafter referred to as nitrate) concentrations exceeded the Federal drinking-water regulation of 10 milligrams per liter in three areas in Idaho\" the Idaho National Engineering Laboratory, the area north of Pocatello (Fort Hall area), and the area surrounding Burley. Water from many wells in the Twin Falls area also contained elevated (greater than two milligrams per liter) nitrate concentrations. Water from domestic wells contained the highest median nitrate concentrations; water from industrial and public supply wells contained the lowest. Nitrate concentrations decreased with increasing well depth, increasing depth to water (unsaturated thickness), and increasing depth below water table (saturated thickness). Kjeldahl nitrogen concentrations decreased with increasing well depth and depth below water table. The relation between kjeldahl nitrogen concentrations and depth to water was poor. Nitrate and total phosphorus concentrations in water from wells were correlated among three hydrogeomorphic regions in the upper Snake River Basin, Concentrations of nitrate were statistically higher in the eastern Snake River Plain and local aquifers than in the tributary valleys. There was no statistical difference in total phosphorus concentrations among the three hydrogeomorphic regions. Nitrate and total phosphorus concentrations were correlated with land-use classifications developed using the Geographic Information Retrieval and Analysis System. Concentrations of nitrate were statistically higher in area of agricultural land than in areas of rangeland. There was no statistical difference in concentrations between rangeland and urban land and between urban land and agricultural land. There was no statistical difference in total phosphorus concentrations among any of the land-use classifications. Nitrate and total phosphorus concentrations also were correlated with land-use classifications developed by the Idaho Department of Water Resources for the Idaho part of the upper Snake River Basin. Nitrate concentrations were statistically higher in areas of irrigated agriculture than in areas of dryland agriculture and rangeland. There was no statistical difference in total phosphorus concentrations among any of the Idaho Department of Water Resources land-use classifications. Data were sufficient to assess long-term trends of nitrate concentrations in water from only eight wells: four wells north of Burley and four wells northwest of Pocatello. The trend in nitrate concentrations in water from all wells in upward. The following organic compounds were detected in ground water in the upper Snake River Basin: cyanazine, 2,4-D DDT, dacthal, diazinon, dichloropropane, dieldrin, malathion, and metribuzin. Of 211 wells sampled for organic compounds, water from 17 contained detectable concentrations.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri944135","usgsCitation":"Rupert, M.G., 1994, Analysis of data on nutrients and organic compounds in ground water in the upper Snake River basin, Idaho and western Wyoming, 1980-91: U.S. Geological Survey Water-Resources Investigations Report 94-4135, iii, 40 p., https://doi.org/10.3133/wri944135.","productDescription":"iii, 40 p.","numberOfPages":"45","temporalStart":"1980-01-01","temporalEnd":"1991-12-31","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":159318,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1994/4135/report-thumb.jpg"},{"id":58317,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1994/4135/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Idaho;Montana;Nevada;Utah;Wyoming","otherGeospatial":"Snake River Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -115.0,41.5 ], [ -115.0,45.0 ], [ -110.0,45.0 ], [ -110.0,41.5 ], [ -115.0,41.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad0e4b07f02db680a42","contributors":{"authors":[{"text":"Rupert, Michael G. mgrupert@usgs.gov","contributorId":1194,"corporation":false,"usgs":true,"family":"Rupert","given":"Michael","email":"mgrupert@usgs.gov","middleInitial":"G.","affiliations":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"preferred":true,"id":201575,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":29137,"text":"wri924159 - 1994 - Hydrogeology, water quality, and potential for contamination of the Upper Floridan aquifer in the Silver Springs ground-water basin, central Marion County, Florida","interactions":[],"lastModifiedDate":"2012-02-02T00:08:50","indexId":"wri924159","displayToPublicDate":"1995-04-01T00:00:00","publicationYear":"1994","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":342,"text":"Water-Resources Investigations Report","code":"WRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"92-4159","title":"Hydrogeology, water quality, and potential for contamination of the Upper Floridan aquifer in the Silver Springs ground-water basin, central Marion County, Florida","docAbstract":"The Upper Floridan aquifer, composed of a thick sequence of very porous limestone and dolomite, is the principal source of water supply in the Silver Springs ground-water basin of central Marion County, Florida. The karstic nature of the local geology makes the aquifer susceptible to contaminants from the land surface. Contaminants can enter the aquifer by seepage through surficial deposits and through sinkholes and drainage wells. Potential contaminants include agricultural chemicals, landfill leachates and petroleum products from leaking storage tanks and accidental spills. More than 560 sites of potential contamination sources were identified in the basin in 1990. Detailed investigation of four sites were used to define hydrologic conditions at representative sites. Ground-water flow velocities determined from dye trace studies ranged from about 1 foot per hour under natural flow conditions to about 10 feet per hour under pumping conditions, which is considerably higher than velocities estimated using Darcy's equation for steady-state flow in a porous medium. Water entering the aquifer through drainage wells contained bacteria, elevated concentrations of nutrients, manganese and zinc, and in places, low concentrations of organic compounds. On the basis of results from the sampling of 34 wells in 1989 and 1990, and from the sampling of water entering the Upper Floridan aquifer through drainage wells, there has been no widespread degradation of water quality in the study area. In an area of karst, particularly one in which fracture flow is significant, evaluating the effects from contaminants is difficult and special care is required when interpolating hydrogeologic data from regional studies to a specific.

All opening and closing of files are now done automatically by the program. Names of input data files are entered either interactively or using a batch-mode script file. Names of output files, created automatically by the program, are based on the name of the input file. In the interactive mode, messages are written to the screen during execution to allow the user to monitor the status and progress of the simulation and to anticipate total running time. Information reported and updated during a simulation include the current pumping period and time step, number of particle moves, and percentage completion of the current time step. The batch mode enables a user to run a series of simulations consecutively, without additional control. A report of the model's activity in the batch mode is written to a separate output file, allowing later review. The user has several options for creating separate output files for different types of data. The formats are compatible with many commercially available applications, which facilitates graphical postprocessing of model results. Geohydrology and Evaluation of Stream-Aquifer Relations in the Apalachicola-Chattahoochee-Flint River Basin, Southeastern Alabama, Northwestern Florida, and Southwestern Georgia By Lynn J. Torak, Gary S. Davis, George A. Strain, and Jennifer G. Herndon Abstract The lower Apalachieola-Chattahoochec-Flint River Basin is underlain by Coastal Plain sediments of pre-Cretaceous to Quaternary age consisting of alternating units of sand, clay, sandstone, dolomite, and limestone that gradually thicken and dip gently to the southeast. The stream-aquifer system consism of carbonate (limestone and dolomite) and elastic sediments, which define the Upper Floridan aquifer and Intermediate system, in hydraulic connection with the principal rivers of the basin and other surface-water features, natural and man made. Separate digital models of the Upper Flori-dan aquifer and Intermediate system were constructed by using the U.S. Geological Survey's MODular Finite-Element model of two dimensional ground-water flow, based on concep- tualizations of the stream-aquifer system, and calibrated to drought conditions of October 1986. Sensitivity analyses performed on the models indicated that aquifer hydraulic conductivity, lateral and vertical boundary flows, and pumpage have a strong influence on groundwater levels. Simulated pumpage increases in the Upper Floridan aquifer, primarily in the Dougherty Plain physiographic district of Georgia,. caused significant reductions in aquifer discharge to streams that eventually flow to Lake Seminole and the Apalachicola River and Bay. Simulated pumpage increases greater than 3 times the October 1986 rates caused drying ofsome stream reaches and parts of the Upper Floridan aquifer in Georgia. Water budgets prepared from simulation results indicate that ground- water discharge to streams and recharge by horizontal and vertical flow are the principal mechanisms for moving water through the flow system. The potential for changes in ground-water quality is high in areas where chemical constituents can be mobilized by these mechanisms. Less than 2 percent of ground-water discharge to streams comes from the Intermediate system; thus, it plays a minor role in the hydrodynamics of the stream- aquifer system.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri944115","usgsCitation":"Konikow, L.F., Granato, G., and Hornberger, G., 1994, User's guide to revised method-of-characteristics solute-transport model (MOC--version 31): U.S. Geological Survey Water-Resources Investigations Report 94-4115, iv, 63 p. , https://doi.org/10.3133/wri944115.","productDescription":"iv, 63 p.

The removal of brine from Great Sail was part of an effort to lower the level of Great Salt Lake when the water level was at a high in 1986. These data were used to prepare a salt budget that indicates about 695 million tons of salt or about 14.2 percent of salt contained in Great Salt Lake was pumped into West Pond. Of the 695 million tons of salt pumped into West Pond, 315 million tons (45 percent) were dissolved in West Pond, 71 million tons (10.2 percent) formed a salt crust at the bottom of the pond, 10 million tons (1.4 percent) infiltrated the subsurface areas inundated by storage in the pond, 88 million tons (12.7 percent) were withdrawn by American Magnesium Corporation, and 123 million tons (17.7 percent) discharged from the pond through the Newfoundland weir. About 88 million tons (13 percent) of the salt pumped from the lake could not be accounted for in the salt budget. About 94 million tons of salt (1.9 percent of the total salt in Great Salt Lake) flowed back to Great Salt Lake.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nUSGS Earth Science Information Center, Open-File Reports Section [distributor],","doi":"10.3133/wri934028","usgsCitation":"Wold, S., and Waddell, K., 1994, Salt budget for West Pond, Utah, April 1987 to June 1989: U.S. Geological Survey Water-Resources Investigations Report 93-4028, iv, 20 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri934028.","productDescription":"iv, 20 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":160085,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1993/4028/report-thumb.jpg"},{"id":59332,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1993/4028/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fdf2e","contributors":{"authors":[{"text":"Wold, S.R.","contributorId":29473,"corporation":false,"usgs":true,"family":"Wold","given":"S.R.","email":"","affiliations":[],"preferred":false,"id":203468,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Waddell, K.M.","contributorId":59009,"corporation":false,"usgs":true,"family":"Waddell","given":"K.M.","email":"","affiliations":[],"preferred":false,"id":203469,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":19539,"text":"ofr94586 - 1994 - Chemistry of spring and well waters on Kilauea Volcano, Hawaii, and vicinity","interactions":[],"lastModifiedDate":"2019-06-06T13:04:03","indexId":"ofr94586","displayToPublicDate":"1995-04-01T00:00:00","publicationYear":"1994","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"94-586","title":"Chemistry of spring and well waters on Kilauea Volcano, Hawaii, and vicinity","docAbstract":"Published and new data for chemical and isotopic samples from wells and springs on Kilauea Volcano and vicinity are presented. These data are used to understand processes that determine the chemistry of dilute meteoric water, mixtures with sea water, and thermal water. Data for well and spring samples of non-thermal water indicate that mixing with sea water and dissolution of rock from weathering are the major processes that determine the composition of dissolved constituents in water. Data from coastal springs demonstrate that there is a large thermal system south of the lower east rift of Kilauea. Samples of thermal water from shallow wells in the lower east rift and vicinity have rather variable chemistry indicating that a number of processes operate in the near surface. Water sampled from the available deep wells is different in composition from the shallow thermal water, indicating that generally there is not a significant component of deep water in the shallow wells. Data for samples from available deep wells show significant gradients in chemistry and steam content of the reservoir fluid. These gradients are interpreted to indicate that the reservoir tapped by the existing wells is an evolving vapor-dominated system.

A study was completed to determine if the JUP possibly could be used for conservation storage for any number of days from April 15 through May 14 under certain hydrologic conditions. The methods of the study were: (1) Frequency analysis of recorded daily mean discharge data for streamflow-gaging stations upstream and downstream from Pueblo Reservoir, and (2) Implementation of the extended streamflow prediction (ESP) procedure for the Arkansas River basin upstream from the reservoir. The frequency analyses enabled estimation of daily discharges at selected exceedance probabilities (EP's), including the 0.01 EP that was used in design of the flood- storage capacity of Pueblo Reservoir. The ESP procedure enabled probabilistic forecasts of inflow volume to the reservoir for April 15 through May 14. Daily discharges derived from the frequency analyses were routed through Pueblo Reservoir to estimate evacuation dates of the JUP for different reservoir inflow volumes; the estimates indicated a relation between the inflow volume and the JUP evacuation date. To apply the study results, only a ESP forecast of the April 15-May 14 reservoir inflow volume is needed. Study results indicate the JUP possibly could be used as late as May 5 depending on the forecast inflow volume.","language":"ENGLISH","publisher":"U.S. Geological Survey :\r\nEarth Science Information Center, Open-File Reports Section [distributor],","doi":"10.3133/wri944054","usgsCitation":"Kuhn, G., and Nickless, R., 1994, Use of frequency analysis and the extended streamflow prediction procedure to estimate evacuation dates for the joint-use pool of Pueblo Reservoir, Colorado: U.S. Geological Survey Water-Resources Investigations Report 94-4054, v, 46 p. :ill., map ;28 cm., https://doi.org/10.3133/wri944054.","productDescription":"v, 46 p. :ill., map ;28 cm.","costCenters":[],"links":[{"id":159359,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1994/4054/report-thumb.jpg"},{"id":57000,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1994/4054/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a17e4b07f02db60458a","contributors":{"authors":[{"text":"Kuhn, Gerhard","contributorId":102080,"corporation":false,"usgs":true,"family":"Kuhn","given":"Gerhard","email":"","affiliations":[],"preferred":false,"id":199324,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nickless, R.C.","contributorId":85229,"corporation":false,"usgs":true,"family":"Nickless","given":"R.C.","email":"","affiliations":[],"preferred":false,"id":199323,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":18446,"text":"ofr94640A - 1994 - Analytical results, mineralogical data, and distributions of anomalies for elements and minerals in three mother lode-type gold deposits, Hodson mining district, Calaveras County, California","interactions":[],"lastModifiedDate":"2012-02-02T00:07:35","indexId":"ofr94640A","displayToPublicDate":"1995-04-01T00:00:00","publicationYear":"1994","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"94-640","chapter":"A","title":"Analytical results, mineralogical data, and distributions of anomalies for elements and minerals in three mother lode-type gold deposits, Hodson mining district, Calaveras County, California","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr94640A","usgsCitation":"Chaffee, M., and Sutley, S.J., 1994, Analytical results, mineralogical data, and distributions of anomalies for elements and minerals in three mother lode-type gold deposits, Hodson mining district, Calaveras County, California: U.S. Geological Survey Open-File Report 94-640, iii, 216 p.; ill., maps ;28 cm., https://doi.org/10.3133/ofr94640A.","productDescription":"iii, 216 p.; ill., maps ;28 cm.","costCenters":[],"links":[{"id":152529,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1994/0640a/report-thumb.jpg"},{"id":47800,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1994/0640a/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac9e4b07f02db67c3ee","contributors":{"authors":[{"text":"Chaffee, M.A.","contributorId":108049,"corporation":false,"usgs":true,"family":"Chaffee","given":"M.A.","affiliations":[],"preferred":false,"id":179145,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sutley, S.

These relations were examined for five large wastewater-treatment plants in the Chicago area, Illinois. At the three largest treatment plants, two major changes in wastewater-treatment practices were identified--the cessation of chlorination and the implementation of Chicago's Tunnel and Reservoir Plan (TARP). Other changes, such as improved aeration and expansion of the facilities, also were made at some of the treatment plants. At the Calumet Water Reclamation Plant, median densities of fecal coliform bacteria in the effluent increased from 3,100 to 1,200,000 colonies per 100 milliliters after the cessation of chlorination. Median densities at the nearest downstream monitoring site increased from 9,500 to 250,000 colonies per 100 milliliters. Similar changes in bacteria densities were indicated for other treatment plants and stream-monitoring sites, but increases in densities of fecal coliform bacteria were not indicated at distances greater than 7 miles downstream. Substantial changes in effluent and stream-water quality, primarily improvements, were identified after the implemen- of TARP and improvements in aeration. Decreases in some of the largest concentrations of ammonia were particularly notable and were likely results of the cape and treatment of combined sewer overflows by TARP. Improvements in water quality were commonly related to climatic season, with greater changes taking place during warm periods. Substantial decreases in concentrations were identified for many constituents, including oxygen demand, ammonia, bacteria, and cyanide. The water-quality data available for this study were considered to be more accurate and were more comprehensive than data from most other monitoring programs. The results of this study, however, identified some needed enhancements to increase the usefulness of the data for additional purposes and analyses.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nU.S. Geological Survey-ESIC, Open-File Reports Section [distributor],","doi":"10.3133/wri934188","usgsCitation":"Terrio, P.J., 1994, Relations of changes in wastewater-treatment practices to changes in stream-water quality during 1978-88 in the Chicago area, Illinois, and implications for regional and national water-quality assessments: U.S. Geological Survey Water-Resources Investigations Report 93-4188, v, 56 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri934188.","productDescription":"v, 56 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":160574,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1993/4188/report-thumb.jpg"},{"id":58907,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1993/4188/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a69e4b07f02db63bec7","contributors":{"authors":[{"text":"Terrio, P.
