Origins and distribution of saline ground waters in the Floridan Aquifer in coastal southwest Florida
W.C. Steinkampf
1982, Water-Resources Investigations Report 82-4052
Twenty-three ground-water samples from the Floridan aquifer in coastal southwest Florida show that water quality deteriorates to the south and west. The waters grade from a fresh calcium magnesium bicarbonate sulfate type to a very saline sodium magnesium chloride type downgradient. Bromide-chloride and specific conductance ratios indicate that dilution of...
Reconnaissance for determining effects of land use and surficial geology on concentrations of selected elements on streambed materials from the coal-mining region, southwestern Indiana, October 1979 to March 1980
W. G. Wilber, Rita R. Boje
1982, Water-Resources Investigations Report 82-4013
Streambed materials were collected in October 1979 from 69 watersheds in Southwest Indiana having predominantly forested, agricultural, reclaimed, and unreclaimed mined land use to determine whether concentrations of sorbed and acid-soluble metals and trace elements were affected by land use and surficial geology. Analysis of variance indicated that 10% or...
Identification codes for organizations listed in computerized data systems of the U.S. Geological Survey
Melvin D. Edwards, Beverly M. Josefson
1982, Open-File Report 82-921
This report contains codes for the identification of public and private organizations listed in computerized data systems. These codes are used by the U.S. Geological Survey 's National Water Data Exchange (NAWDEX), National Water Data Storage and Retrieval System (WATSTORE), National Cartographic Information Center (NCIC), Office of Water Data Coordination...
The effects of channel excavation on water-quality characteristics of the Black River and on ground-water levels near Dunn, North Carolina
C.E. Simmons, S.A. Watkins
1982, Water-Resources Investigations Report 82-4083
During 1976-81 data were collected at three sites on the Black River near Dunn, N.C., to define the effects of channel excavation on stream quality and on ground-water levels in nearby areas. One of the data sites was located upstream from the five-mile long excavated reach and served as a...
Water-quality characteristics of six small, semiarid watersheds in the Green River coal region of Colorado
John T. Turk, Randolph S. Parker
1982, Water-Resources Investigations Report 81-19
Analysis of major and trace constituents in streams flowing through six semiarid watersheds indicates that the stream chemistry is characterized by saturation with respect to common carbonate minerals (calcium, magnesium, iron, manganese, and lead). The solubility of the carbonate minerals may be a major control on the absolute and relative...
Map showing selected surface-water data for the Alton-Kolob coal-fields area, Utah
Don Price
1982, IMAP 1235-D
This is one of a series of maps that describe the geology and related natural resources of the Alton-Kolob coal-fields area, Utah. Streamflow records used to compile the map and the following table were collected by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division...
Proceedings, Illinois water-data-users meeting
L. G. Toler (compiler)
1982, Open-File Report 82-1001
The increased demand for water and concern for the quality of the water resources of Illinois have lead to increased demand for water-resources data. Representatives of the major water-data-collecting and water-data-using agencies met in Peoria, Illinois, on February 23-24, 1982, to (1) exchange information on current water-data programs and needs;...
Downstream effects of reservoir releases to the Potomac River from Luke, Maryland, to Washington, D.C.
T. J. Trombley
1982, Water-Resources Investigations Report 82-4062
A digital computer flow-routing model was developed for the Potomac River in order to determine the downstream effects of flow releases from the Bloomington and Savage River Reservoirs. Both reservoirs are located above Luke, Maryland approximately 230 miles upstream from Washington, D. C. The downstream effects of reservoir releases were...
