The objectives of the NAWQA program are to describe the present and future water quality of large, representative parts of the United States's surface- and ground-water resources and to identify the primary natural and man-made factors that affect the quality of these resources. The final product of the program will be information that may be used by water-resource policy makers and managers at national, State, and local levels.
\nThe NAWQA program encompasses 60 study units. These units are delineated by hydrologic systems that include parts of most of the Nation's major river basins and aquifer systems. Study units range in size from 1,000 mi2 (square miles) to more than 60,000 mi2 and represent 60 to 70 percent of the Nation's water use and population served by public water supplies. The first group of 20 study-unit investigations began in 1991. A second group of 20 study-unit investigations began in 1994, which includes the Northern New England Basins study unit.

In meeting these goals, the program will produce a wealth of water-quality information that will be useful to policymakers and managers at the National, State, and local levels.
\nStudies of 60 hydrologic systems that include parts of most major river basins and aquifer systems (study-unit investigations) are the building blocks of the national assessment. The 60 study units range in size from 1,000 to about 60,000 mi2 and represent 60 to 70 percent of the Nation's water use and population served by public water supplies. Twenty study-unit investigations were started in 1991, 20 additional studies started in 1994, and 20 more are planned to start in 1997. The Central Arizona Basins study unit began assessment activities in 1994.

Ground water affects our everyday lives, not just in terms of how much water is available, but also in terms of the position of ground-water levels in relation to land surface. Knowledge of ground-water levels is needed by Federal, State, and local agencies to help plan, manage, and protect ground-water supplies, and by private construction companies for site planning and evaluation.
\nA primary part of the mission of the U.S. Geological Survey (USGS), Water Resources Division, is the systematic collection of ground-water, surface-water, and water-quality data. These data are needed to manage and protect the nation's water resources. The Massachusetts-Rhode Island District of the USGS, in cooperation with the Massachusetts Department of Environmental Management (DEM), Office of Water Resources, and county and town environmental agencies, has maintained a network of observation wells throughout the Commonwealth since the mid 1930's. The purpose of this network is to monitor seasonal and long-term changes in groundwater storage in different lithologic, topographic, and geographic settings. These data are analyzed to provide a monthly index of ground-water conditions to aid in water-resources management and planning, and to define long-term changes in water levels resulting from manmade stresses (such as pumping and construction-site drainage) and natural stresses (such as floods and droughts).

The investigation included measurements of the discharge of selected springs and measurements of the physical and chemical characteristics of water from selected springs and wells in the LincolnPoint - Bird Island area. This report contains data for twenty-one distinct springs in the study area including two springs beneath the surface of Utah Lake at Bird Island. Data from this study, combined with data from previous studies, indicate that the location of springs in the Lincoln Point - Bird Island area probably is controlled by fractures that are the result of faulting. Measured discharge of springs in the Lincoln Point - Bird Island area ranged from less than 0.01 cubic foot per second to 0.84 cubic foot per second. Total discharge in the study area, including known unmeasured springs and seeps, is estimated to be about 5 cubic feet per second. Reported and measured temperatures of water from springs and wells in the Lincoln Point - Bird Island area ranged from 16.0 degrees Celsius to 36.5 degrees Celsius. Dissolved-solids con-centrations ranged from 444 milligrams per liter to 7,932 milligrams per liter, and pH ranged from 6.3 to 8.1. Physical and chemical characteristics of spring and well water from the west side of Lincoln Point were virtually identical to the physical and chemical characteristics of water from the submerged Bird Island springs, indicating a similar source for the water. Water chemistry, isotope analyses, and geothermometer calculations indicate deep circulation of water discharging from the springs and indicate that the source of recharge for the springs at Lincoln Point and Bird Island does not appear to be localized in the LincolnPoint - Bird Island area.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nUSGS Earth Science Information Center, Open-File Reports Section [distributor],","doi":"10.3133/wri934219","usgsCitation":"Baskin, R.L., Spangler, L., and Holmes, W., 1994, Physical characteristics and quality of water from selected springs and wells in the Lincoln Point-Bird Island area, Utah Lake, Utah: U.S. Geological Survey Water-Resources Investigations Report 93-4219, vi, 54 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri934219.","productDescription":"vi, 54 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":123936,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1993/4219/report-thumb.jpg"},{"id":54892,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1993/4219/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":54893,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1993/4219/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":54894,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1993/4219/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adbe4b07f02db685b8e","contributors":{"authors":[{"text":"Baskin, R.

The long-term goals of the NAWQA Program are to describe the status of and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources and to identify the major natural and human factors that affect the quality of these resources. In addressing these goals, the program will produce a wealth of water-quality information that will be useful to policymakers and managers at national, State, and local levels.
\nThe NAWQA Program emphasis is on regional water-quality problems. The program will not diminish the need for smaller studies and monitoring presently designed and conducted by Federal, State, and local agencies to meet their individual needs. The NAWQA Program, however, will provide a large-area framework for conducting many of these activities and an understanding about national and regional water-quality conditions that cannot be acquired from individual, local programs and studies.
\nStudies of 60 hydrologic systems that include parts of most major river basins and aquifer systems (study-unit investigations) are the building blocks of the national assessment. Areas of the 60 study units range in size from less than 1,000 to more than 60,000 square miles (mi2) and represent 60 to 70 percent of the Nation's water use and population served by public water supplies. Twenty study-unit investigations were started in 1991, 20 additional started in 1994, and 20 are planned to start in 1997. Assessment activities in the South-Central Texas study area (see fig.) began in 1994.

These aquifers area subject to contamination because of their shallow water-table depth and highly transmissive sediments. The possibility for contamination of water-supply wells in valley-fill aquifers can be minimized by excluding activities that could contaminate areas that contribute water to supply wells. \r\n\r\n An area that contributes water to a well is identified in this report as either an area of diversion, time-of-travel area, or contributing area. The area of diversion is a projection to land surface of the valley-fill aquifer volume through which water is diverted to a well and the time-of travel area is that fraction of the area of diversion through which water moves to the well in a specified time. The contributing area, the largest of three areas, includes the area of diversion but also incorporates bedrock uplands and other area that contribute water. \r\n\r\n Methods for delineating areas of diversion and contributing areas in valley-fill aquifers, described and compared in order of increasing complexity, include fixed radius, uniform flow, analytical, semianalytical, and numerical modeling. Delineated areas are considered approximations because the hydraulic properties and boundary conditions of the real ground-water system are simplified even in the most complex numerical methods. \r\n\r\n Successful application of any of these methods depends on the investigator's understanding of the hydrologic system in and near the well field, and the limitations of the method. The hydrologic system includes not only the valley-fill aquifer but also the regional surface-water and ground-water flow systems within which the valley is situated. As shown by numerical flow simulations of a well field in the valley-fill aquifer along Marsh Creek Valley near Asaph, Pa., water from upland bedrock sources can provide nearly all the water contributed to the well.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr92635","usgsCitation":"Risser, D.W., and Madden, T.M., 1994, Evaluation of methods for delineating areas that contribute water to wells completed in valley-fill aquifers in Pennsylvania: U.S. Geological Survey Open-File Report 92-635, 82 p., https://doi.org/10.3133/ofr92635.","productDescription":"82 p.","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":50178,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1992/0635/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":152405,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1992/0635/report-thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e4e4b07f02db5e60fd","contributors":{"authors":[{"text":"Risser, Dennis W. 0000-0001-9597-5406 dwrisser@usgs.gov","orcid":"https://orcid.org/0000-0001-9597-5406","contributorId":898,"corporation":false,"usgs":true,"family":"Risser","given":"Dennis","email":"dwrisser@usgs.gov","middleInitial":"W.","affiliations":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"preferred":true,"id":183002,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Madden, Thomas M.","contributorId":18403,"corporation":false,"usgs":true,"family":"Madden","given":"Thomas","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":183003,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":19236,"text":"ofr9368 - 1994 - Flood data for the Sacramento River and Butte Basin, Sacramento Valley, California, 1980-90","interactions":[],"lastModifiedDate":"2022-12-23T22:45:23.536219","indexId":"ofr9368","displayToPublicDate":"1995-05-01T00:00:00","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":"93-68","title":"Flood data for the Sacramento River and Butte Basin, Sacramento Valley, California, 1980-90","docAbstract":"Floodflows and peak states of floods were measured and channel cross sections were surveyed at sites along the Sacramento River and in Butte Basin, Sacramento Valley, California, during 1980-90 to document magnitudes of flooding and channel changes.

In addressing these goals, the program will provide a wealth of water- quality information that will be useful to policy makers and managers at the national, State, and local levels. \r\n\r\n\r\nA major asset of the NAWQA program is that it will allow for the integration of water-quality information collected at several scales. A major component of the program is the study-unit investigation-the foundation of national- level assessment. The 60 study units of the NAWQA program are hydrologic systems that include parts of most major river basins and aquifer systems of the conterminous United States. These study units cover areas of 1,000 to more than 60,000 square miles and represent 60 to 70 percent of the Nation's water use and population served by public water supplies. Investigations of the first 20 study units began in 1991.

During the 1970's and 1980's, accidental releases of more than 1,300 cubic meters of various types of fuel occurred at the airstrip site adjacent to the lake. To aid an assessment of the potential risk 10 the quality of water in the lake posed by fuel remaining in the subsurface, the hydrologic interaction between the lake and ground water at the airstrip site was examined. The study area lies within the region of continuous permafrost where hydrologic processes are largely controlled by the short annual thaw season and the presence of near-surface permafrost. Runoff occurs for only a short period each year, typically from early or mid-June to late September, and a shallow ground- water system develops during approximately the same period as a result of shallow thawing of the subsurface. During the spring and summer of 1993, snowpack and surface-water data were collected throughout the Imikpuk Lake basin, and subsurface- flow-system data were collected at the airstrip site. The total annual inflow to the lake was estimated 10 be approximately 300,000 cubic meters per year, based on four methods of estimation. The ground-water flow system at the airstrip site is complex, primarily because of variations in local land-surface topography. Subsurface frost-elevation data indicate that a permafrost ridge exists beneath one of the elevated building pads at the site. Similar ridges beneath elevated roadways at the site may act as impediments to ground-water flow, reducing the flux of subsurface water to Imikpuk Lake. However, on the basis of the assumption that such impediments do not reduce flux substantially, the ground-water flux from the airstrip site was estimated to be approximately 173 cubic meters per year--less than 0.1 percent of the estimated annual inflow to Imikpuk Lake.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nUSGS Earth Science Information Center, Open-File Reports Section [distributor],","doi":"10.3133/ofr94367","usgsCitation":"McCarthy, K.A., Solin, G.L., and Trabant, D., 1994, Assessment of the hydrologic interaction between Imikpuk Lake and the adjacent airstrip site near Barrow, Alaska, 1993: U.S. Geological Survey Open-File Report 94-367, iv, 27 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr94367.","productDescription":"iv, 27 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":153135,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1994/0367/report-thumb.jpg"},{"id":49555,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1994/0367/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abae4b07f02db671ce7","contributors":{"authors":[{"text":"McCarthy, Kathleen A. mccarthy@usgs.gov","contributorId":1159,"corporation":false,"usgs":true,"family":"McCarthy","given":"Kathleen","email":"mccarthy@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":181925,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Solin, Gary L. glsolin@usgs.gov","contributorId":5675,"corporation":false,"usgs":true,"family":"Solin","given":"Gary","email":"glsolin@usgs.gov","middleInitial":"L.","affiliations":[],"preferred":true,"id":181926,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Trabant, Dennis","contributorId":99990,"corporation":false,"usgs":true,"family":"Trabant","given":"Dennis","affiliations":[],"preferred":false,"id":181927,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":17742,"text":"ofr94383 - 1994 - Summary of water-resources activities of the U.S. Geological Survey in Colorado - Fiscal years 1992-93","interactions":[],"lastModifiedDate":"2022-12-13T20:18:53.72608","indexId":"ofr94383","displayToPublicDate":"1995-05-01T00:00:00","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":"94-383","title":"Summary of water-resources activities of the U.S. Geological Survey in Colorado - Fiscal years 1992-93","docAbstract":"Water-resources activities of the U.S. Geological Survey in Colorado consist of collecting water-resources data and doing interpretive hydrologic investigations.

Joaquin Delta, California","docAbstract":"The Sacramento/San Joaquin Delta was once tidal marshland and was formed by the confluence of the Sacramento and the San Joaquin Rivers. The delta covers more than 1,000 square miles and is bordered by the major population centers of the San Francisco Bay area, Sacramento, and Stockton (fig. 1). The delta took its current form by the 1930's when drainage of 100 islands and tracts and construction of 2,250 miles of levees were completed.
\nThe land surface on the delta islands has progressively subsided below sea level since the early 20th century. The integrity of the levee network is threatened because subsidence increases the differences in water levels maintained by the levees, which can cause levee failure and consequent flooding of the delta islands. Levee failure affects the quality and beneficial use of water in the delta, which is the major source of California's water supply to millions of residents and acres of agricultural land. This Fact Sheet briefly summarizes the research done by the U.S. Geological Survey, in cooperation with the California Department of Water Resources to assess the causes of subsidence, processes that affect subsidence, and carbon fluxes in the delta.

Four aquifer systems have been de- lineated in the study area. Principal aquifers are unconsolidated deposits at altitudes of less than 4,900 feet above sea level and more than 50 feet below land surface. Shallow aquifers are at altitudes of less than 4,900 feet and less than 50 feet below land surface. Upland aquifers are above 4,900 feet and provide recharge to the principal aquifers. Thermal aquifers, defined as those having a water temperature greater than 30 degrees Celsius, are also present. Ground water used in Dayton, Stagecoach, and Churchill Valleys is pumped from principal aquifers in unconsolidated basin-fill deposits. Ground water in these aquifers originates as precipitation in the adjacent mountains and is recharged by the Carson River and by underflow from adjacent upstream valleys. Ground-water flow is generally parallel to the direction of surface-water flow in the Carson River. Ground water is discharged by pumping, evapo- transpiration, and underflow into the Carson River. The results of geochemical modeling indicate that as ground water moves from upland aquifers in mountainous recharge areas to principal aquifers in basin-fill deposits, the following processes probably occur: (1) plagioclase feldspar, sodium chloride, gypsum (or pyrite), potassium feldspar, and biotite dissolve; (2) calcite precipitates; (3) kaolinite forms; (4) small amounts of calcium and magnesium in the water exchange for potassium on aquifer minerals; and (5) carbon dioxide is gained or lost. The geochemical models are consistent with (1) phases identified in basin- fill sediments; (2) chemical activity of major cations and silica; (3) saturation indices of calcite and amorphous silica; (4) phase relations for aluminosilicate minerals indicated by activity diagrams; and (5) results of optical, X-ray diffraction, and scanning-electron microscopy examination of mineral grains in the aquifer sediments. Sulfur-isotopic composition of ground- water samples also supports the models. In general, the quality of ground water in the study area meets Nevada State drinking-water standards and is acceptable for most uses. In addition to analysis for major ions, samples were analyzed for 22 inorganic trace elements, 3 nutrients, and 4 radionuclides. Selenium in 1 sample is the only constituent that exceeded Nevada State primary drinking-water standards. Nevada State secondary- drinking water standards were exceeded for fluoride in 1 sample, for iron in 7 samples, and for manganese in 19 samples. Minor constituent con- centrations are generally the result of local redox conditions, and are primarily from minerals in volcanic and marine metasedimentary rocks, metal- oxide coatings on mineral grains, and organic matter.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nUSGS Earth Science Information Center, Open-File Reports Section [distributor],","doi":"10.3133/ofr93356","usgsCitation":"Thomas, J., and Lawrence, S.J., 1994, Ground-water quality and geochemistry in Dayton, Stagecoach, and Churchill Valleys, western Nevada: U.S. Geological Survey Open-File Report 93-356, v, 69 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr93356.","productDescription":"v, 69 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":153924,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1993/0356/report-thumb.jpg"},{"id":50727,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1993/0356/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b06e4b07f02db69a378","contributors":{"authors":[{"text":"Thomas, James M.","contributorId":97880,"corporation":false,"usgs":true,"family":"Thomas","given":"James M.","affiliations":[],"preferred":false,"id":183900,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lawrence, Stephen J. slawrenc@usgs.gov","contributorId":1885,"corporation":false,"usgs":true,"family":"Lawrence","given":"Stephen","email":"slawrenc@usgs.gov","middleInitial":"J.","affiliations":[{"id":316,"text":"Georgia Water Science Center","active":true,"usgs":true}],"preferred":true,"id":183899,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":28227,"text":"wri944012 - 1994 - Description and application of capture zone delineation for a wellfield at Hilton Head Island, South Carolina","interactions":[],"lastModifiedDate":"2023-12-15T22:06:38.127904","indexId":"wri944012","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":"94-4012","title":"Description and application of capture zone delineation for a wellfield at Hilton Head Island, South Carolina","docAbstract":"Ground-water capture zone boundaries for individual pumped wells in a confined aquffer were delineated by using groundwater models. Both analytical and numerical (semi-analytical) models that more accurately represent the $round-water-flow system were used. All models delineated 2-dimensional boundaries (capture zones) that represent the areal extent of groundwater contribution to a pumped well. The resultant capture zones were evaluated on the basis of the ability of each model to realistically rapresent the part of the ground-water-flow system that contributed water to the pumped wells. Analytical models used were based on a fixed radius approach, and induded; an arbitrary radius model, a calculated fixed radius model based on the volumetric-flow equation with a time-of-travel criterion, and a calculated fixed radius model derived from modification of the Theis model with a drawdown criterion. Numerical models used induded the 2-dimensional, finite-difference models RESSQC and MWCAP. The arbitrary radius and Theis analytical models delineated capture zone boundaries that compared least favorably with capture zones delineated using the volumetric-flow analytical model and both numerical models. The numerical models produced more hydrologically reasonable capture zones (that were oriented parallel to the regional flow direction) than the volumetric-flow equation. The RESSQC numerical model computed more hydrologically realistic capture zones than the MWCAP numerical model by accounting for changes in the shape of capture zones caused by multiple-well interference. The capture zone boundaries generated by using both analytical and numerical models indicated that the curnmtly used 100-foot radius of protection around a wellhead in South Carolina is an underestimate of the extent of ground-water capture for pumped wetis in this particular wellfield in the Upper Floridan aquifer.

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. The water-resources data were collected mostly in Lowndes County in the vicinity of Valdosta and lesser amounts were collected in surrounding Berrien, Brooks, Cook, Echols, and Lanier Counties.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nUSGS Earth Science Information Center, Open-File Reports Section [distributor],","doi":"10.3133/ofr94350","usgsCitation":"McConnell, J.B., Busenberg, E., and Plummer, N., 1994, Water-resources data for the Valdosta area, south-central Georgia, 1961-93: U.S. Geological Survey Open-File Report 94-350, iv, 58 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr94350.","productDescription":"iv, 58 p. :ill., maps ;28 cm.","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":154060,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1994/0350/report-thumb.jpg"},{"id":49590,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1994/0350/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Georgia","city":"Valdosta","otherGeospatial":"Upper Floridan Aquifer","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -83.95751953125,\n 30.557530797259172\n ],\n [\n -83.95751953125,\n 31.62064369245056\n ],\n [\n -82.7764892578125,\n 31.62064369245056\n ],\n [\n -82.7764892578125,\n 30.557530797259172\n ],\n [\n -83.95751953125,\n 30.557530797259172\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a08e4b07f02db5f9d2e","contributors":{"authors":[{"text":"McConnell, James B.","contributorId":28224,"corporation":false,"usgs":true,"family":"McConnell","given":"James","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":181939,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Busenberg, Eurybiades ebusenbe@usgs.gov","contributorId":2271,"corporation":false,"usgs":true,"family":"Busenberg","given":"Eurybiades","email":"ebusenbe@usgs.gov","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":181937,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Plummer, Niel 0000-0002-4020-1013 nplummer@usgs.gov","orcid":"https://orcid.org/0000-0002-4020-1013","contributorId":190100,"corporation":false,"usgs":true,"family":"Plummer","given":"Niel","email":"nplummer@usgs.gov","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":181938,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":64480,"text":"i2402 - 1994 - Geologic map of the MTM-15147 quadrangle, Mangala Valles region of Mars","interactions":[],"lastModifiedDate":"2023-07-10T13:56:12.73834","indexId":"i2402","displayToPublicDate":"1995-04-01T00:00:00","publicationYear":"1994","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":320,"text":"IMAP","code":"I","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"2402","title":"Geologic map of the MTM-15147 quadrangle, Mangala Valles region of Mars","docAbstract":"The map area is in the Mangala-Memnonia region (fig. 1), which contains remarkably diverse geologic features and terrain types. Studies of the Mariner 9 images revealed the wide range of ages of the major rock units in this region; age assignments were based on the density of impact craters preserved on the various surfaces (Mutch and others, 1976, p. 56-60; Scott and Carr, 1978; Mutch and Morris, 1979). The region includes ancient cratered highlands, more sparsely cratered smooth plains, young volcanic plains, and the Mangala Valles channel system. The sinuosity of the streamlined landforms within the Mangala Valles, combined with braided channels evident throughout the lower reaches of the valley system, were recognized as indicators that he Mangala area was subject to substantial erosion by a flowing fluid, most likely water (Milton, 1973; Baker and Milton, 1974; Sharp and Malin, 1975). Recent global mapping based on the Viking Orbiter images (Scott and Tanaka, 1986) has refined the relative ages of many rock units on Mars, but it has modified only slightly the basic interpretations of features in the Mangala-Memnonia region.

The upper 15-20 feet of the subsurface consists of varved gypsiferous clay and silt. Below these surfidai deposits the lithology consists of interbedded clay units, silty-clay units, and fine- to medium-grained quartz arenite units in continuous and discontinuous horizons. Clay horizons can cause perched water above the water table. Analyses of selected clay samples indicate that clay units are composed chiefly of kaolinire and mixed-layer illite/ smectite. The main aquifer is representative of a leaky-confined aquifer. Estimated aquifer properties are: transmissivity (T) = 780 feet squared per day, storage coefficient (S) = 3.1 x 10-3, and hydraulic conductivity (K) = 6.0 feet per day. Ground water flows south and southwest; the estimated hydraulic gradient is 5.3 feet per mile. Analyses of water samples indicate that ground water at the HELSTF site is brackish to slightly saline at the top of the main aquifer. Dissolved-solids concentration near the top of the main aquifer ranges from 5,940 to 11,800 milligrams per liter. Predominant ions are sodium and sulfate. At 815 feet below land surface, the largest dissolved-solids concentration measured is 111,000 milligrams per liter, which indicates increasing salinity with depth. Predominant ions are sodium and chloride.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri934192","usgsCitation":"Basabilvazo, G., Myers, R.G., and Nickerson, E.L., 1994, Geohydrology of the High Energy Laser System Test Facility site, White Sands Missile Range, Tularosa Basin, south-central New Mexico: U.S. Geological Survey Water-Resources Investigations Report 93-4192, Report: v, 59 p. , https://doi.org/10.3133/wri934192.","productDescription":"Report: v, 59 p.
