Properties and chemical constituents in ground water from the middle Claiborne Aquifer, Gulf Coast regional aquifer systems, south-central United States
Robert A. Pettijohn, John F. Busby, Michael A. Cervantes
1993, Water-Resources Investigations Report 92-4104
The U.S. Geological Survey used four programs in 1990 to provide external data quality assurance for the National Atmospheric Deposition Program/National Trends Network (NADP/NTN). Results of the intersite- comparison program indicate that 80 and 74 percent of the site operators met the NADP/NTN goals for pH determination and 98 and...
Historical potentiometric surface of the Edwards-Trinity aquifer system and contiguous hydraulically connected units, west-central Texas
Peter W. Bush, Ann F. Ardis, Kirby H. Wynn
1993, Water-Resources Investigations Report 92-4055
The Edwards-Trinity aquifer system is a sequence of near-surface, hydraulically connected, Cretaceous carbonate and quartzose clastic rocks that underlie about 42,000 mi2 of west-central Texas (fig. 1). The aquifer system is currently (1991) being studied as a part of the U.S. Geological Survey's Regional Aquifer-System Analysis (RASA) program, which is...
Properties and chemical constituents in ground water from the lower Wilcox Aquifer, Mississippi Embayment Aquifer System, south-central United States
Robert A. Pettijohn, John F. Busby, Jeffery D. Beckman
1993, Water-Resources Investigations Report 93-4071
The Gulf Coast Regional Aquifer-System Analysis is a study of regional aquifers composed of sediments of mostly Cenozoic age that underlie about 230,000 sq mi of the Gulf Coastal Plain. These regional aquifers are part of three aquifer systems: (1) the Mississippi Embayment Aquifer System, (2) the Texas Coastal Uplands...
Summary of reported agriculture and irrigation water use in Lee County, Arkansas, 1991
T.W. Holland, C.A. Manning, K.L. Stafford
1993, Open-File Report 93-469
This report summarizes the 1991 water-use reporting through the Conservation District Office in Lee County, Arkansas. The number of withdrawal registrations for Lee County was 1,582 (1,533 groundwater and 49 surface water). Water withdrawals reported during the registration process total 3.77 Mgal/d (3.39 Mgal/d groundwater and 0.38 Mgal/d surface water)...

Hydrogeology, water quality, and ground-water-development alternatives in the upper Wood River ground-water reservoir, Rhode Island
D.C. Dickerman, R.W. Bell
1993, Water-Resources Investigations Report 92-4119
The 72.4-square-mile Upper Wood River study area is in the Pawcatuck River basin in southern Rhode Island. Stratified drift is the only principal geologic unit capable of producing yields greater than 0.5 Mgal/d. Transmissivity of the aquifer ranges from 7,600 to 49,200 sq ft/d. Water-table conditions prevail and the aquifer...
Altitude and configuration of the potentiometric surfaces of the upper and lower aquifer systems in Bridgeton, Nockamixon, and Tinicum Townships, Bucks County, Pennsylvania, April 1991 through April 1992
B. Craig McManus, Cynthia J. Rowland
1993, Water-Resources Investigations Report 92-4194
The mapped area in underlain by layered sedimentary rocks chiefly consisting of shale, mudstone, siltstone, and argillite and by a diabase sheet thtat has intruded the sedimentary rocks.  The sedimentary rocks adjacent to the diabase are thermally altered to hornfels.  Water levels in shallow wells completed in the diabase indicate...

T.W. Holland, C.A. Manning, K.L. Stafford
1993, Open-File Report 93-475
This report summarizes the 1991 water-use reporting through the Conservation District Office in Phillips County, Arkansas. The number of withdrawal registrations for Phillips County was 1,109 (1,103 groundwater and 6 surface water). Water withdrawals reported during the registration process total 0.15 Mgal/d (0.15 Mgal/d groundwater and none from surface water)...
Summary of reported agriculture and irrigation water use in Poinsett County, Arkansas, 1991
T.W. Holland, C.A. Manning, K.L. Stafford
1993, Open-File Report 93-487
This report summarizes the 1991 water-use reporting through the Conservation District Office of Poinsett County, Arkansas. The number of withdrawal registrations for Poinsett County was 1,826 (1,644 groundwater and 182 surface water). Water withdrawals reported during the registration process total 15.12 Mgal/d (11.76 Mgal/d groundwater and 3.26 Mgal/d surface water)...
Water resources data, Massachusetts and Rhode Island, water year 1992
R.S. Socolow, T.S. Shepard, G.G. Girouard, R. A. Gadoury
1993, Water Data Report MA-RI-92-1
Water-resources data for the 1992 water year for Massachusetts and Rhode Island consists of stage, discharge, and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 77 gaging stations, month end contents for six lakes and reservoirs, water quality for nine...
Ground-water data for Michigan 1990
G.C. Huffman, C.R. Whited
