This data set consists of digital water-level-change contour for the High Plains aquifer in the Central United States, 1980 to 1994. The High Plains aquifer extends from south of 32 degrees to almost 44 degrees north latitude and from 96 degrees 30 minutes to 104 degrees west longitude. The aquifer underlies about 174,000 square miles in parts of Colorado, Kansas, Nebraska, New Mexico, Okla

IntroductionThe Cheat River Basin is in the Allegheny Plateau and Allegheny Mountain Sections of the Appalachian Plateau Physiographic Province (Fenneman, 1946) and is almost entirely within the state of West Virginia. The Cheat River drains an area of 1,422 square miles in Randolph, Tucker, Preston, and Monongalia Counties in West Virginia and Fayette County in Pennsylvania. From its headwaters i

The White River Basin drains 11,349 square miles of central and southern Indiana and is one of 59 Study Units selected for water-quality assessment as part of the U.S. Geological Survey's National WaterQuality Assessment Program. Defining the environmental setting of the basin and identifying the natural factors and human influences that affect water quality are important parts of the assessment.

The Grand Portage Reservation is located in northeastern Cook County, Minnesota (fig. 1). In 1997 and 1998 the U.S. Geological Survey (USGS) conducted a study, in cooperation with the Grand Portage Band of Chippewa, to determine the quality of water in selected inland lakes and streams in the Reservation. The USGS collected and analyzed water from two streams, two wetlands, and four lakes (fig 1).

This data layer shows the generalized lithologic and geochemical (lithogeochemical) character of near-surface bedrock in the Connecticut, Housatonic, and Thames River Basins and several other small basins that drain into Long Island Sound from Connecticut. The area includes most of Connecticut, western Massachusetts, eastern Vermont, western New Hampshire, and small parts of Rhode Island, New York

Physical, chemical, and biological data were collected at 51 sampling sites in Chester County, Pa., from 1970 through 1994 as part of the Stream Conditions of Chester County Program. This report presents data collected from 1981 through 1994. Physical data include water temperature, instantaneous stream discharge, pH, alkalinity, specific conductance, and dissolved oxygen. Chemical data include la

This fact sheet illustrates comparative water use from ground and surface sources for 1990 and 1995 for the largest categories of use in Kansas: public supply, irrigation, industrial and mining, livestock, and thermoelectric power generation. Total populations, including those served by public-water suppliers and those using private wells, also are illustrated. These data are organized by major ri

This report contains digital data and accompanying documentation for contours for 1980 water-level elevations for the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set was created by digitizing the 1980 water-level elevation contours from a 1:1,000,000-scale base map created by the U.S. Geological Survey High P

This report contains digital data and accompanying documentation for saturated thickness contours of the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set was created by digitizing the saturated thickness contours from a 1:1,000,000-scale base map created by the U.S. Geological Survey High Plains Regional Aquif

Between May and July 1998, 10 monitor wells were drilled near the site of the former Naval Air Warfare Center (NAWC), Warminster, Bucks County, Pa., to monitor water levels and sample ground water in shallow and intermediate water-bearing fractures. The sampling will determine the horizontal and vertical distribution of contaminated ground water migrating from known or suspected sources. Three bor

This report contains digital data and accompanying documentation for aquifer boundaries for the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set was compiled from a digital coverage that was created for publication of paper maps in McGrath and Dugan (1993, Water-level changes in the High Plains aquifer -- pred

This report contains digital data and accompanying documentation for boundaries of areas of little or no saturated thickness within the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. This digital data set was compiled from a digital coverage that was created for publication of paper maps in McGrath and Dugan (1993, Water-level ch
