Effects of land use and surficial geology on flow and water quality of streams in the coal-mining region of southwestern Indiana, October 1979 through September 1980
William G. Wilber, Danny E. Renn, Charles G. Crawford
1985, Water-Resources Investigations Report 85-4234
An assessment of streams in the coal-mining region of southwestern Indiana was done from October 1979 through September 1980 during stable stream flows to provide baseline hydrologic and water-quality information and to document the effect of several natural and human-induced factors on water quality in the region. Streams in southwestern Indiana...
Selected methods for dissolved iron (II, III) and dissolved sulfide (-II) determinations in geothermal waters
D.V. Vivit, E. A. Jenne
1985, Water-Resources Investigations Report 85-4189
Dissolved sulfide (-II) and dissolved iron (II, III) were determined in geothermal well water samples collected at Cerro Prieto, Mexico. Most samples consisted of liquid and gas (two phases) at the instant of collection; and a subset of samples, referred to as ' flashed ' samples, consisted of pressurized steam...
Preparation of polyethylene sacks for collection of precipitation samples for chemical analysis
L.J. Schroder, A.W. Bricker
1985, Water-Resources Investigations Report 85-4067
Polyethylene sacks are used to collect precipitation samples. Washing polyethylene with acetone, hexane, methanol, or nitric acid can change the adsorptive characteristics of the polyethylene. In this study, simulated precipitation at pH 4.5 was in contact with the polyethylene sacks for 21 days; subsamples were removed for chemical analysis at...
Reported withdrawals and estimated use of water in Oklahoma during 1982
J.D. Stoner
1985, Water-Resources Investigations Report 85-4084
Reported water withdrawals in Oklahoma during 1982 were 1,270.64 million gallons per day. The withdrawals were about equally distributed between ground water and surface water with 46 percent being ground water and 54 percent being surface water. In general, the western counties rely on ground water and the eastern counties...
Ground-water flow and solute transport in the Equus beds area, south-central Kansas, 1940-79
J. M. Spinazola, James B. Gillespie, R. J. Hart
1985, Water-Resources Investigations Report 85-4336
Water levels have declined about 30 ft from 1940 to 1980 in part of the Equus beds aquifer in south-central Kansas where the city of Wichita operates a well field. A three-dimensional, finite-difference, groundwater flow model was developed to: (1) Reproduce hydrologic conditions in the flow system between the Equus...
Statistical evaluation of the effects of irrigation on chemical quality of ground water and base flow in three river valleys in north-central Kansas
T.B. Spruill
1985, Water-Resources Investigations Report 85-4156
The chemical quality of groundwater and base flow in three alluvial valleys in Kansas has been changed as a result of 10 or more years of irrigation. Sulfate concentrations in groundwater in the Prairie Dog Creek valley statistically larger during 1981-82 than before irrigation began. Concentrations of calcium, bicarbonate, sulfate,...
Water-quality conditions and an evaluation of ground- and surface-water sampling programs in the Livermore-Amador Valley, California
S. K. Sorenson, P. V. Cascos, R. L. Glass
1985, Water-Resources Investigations Report 84-4352
A program to monitor the ground- and surface water quality in the Livermore-Amador Valley has been operated since 1976. As of 1982, this monitoring network consisted of approximately 130 wells, about 100 of which were constructed specifically for this program, and 9 surface water stations. Increased demand on the groundwater...
Summary of selected water-quality data for the Warrior coal field, Alabama
W. S. Mooty
1985, Open-File Report 85-689
A summary is presented of selected water quality data collected from 1976 to 1984 at 75 surface water sites and 28 test wells in the Warrior coal field in northwestern Alabama. The minimum, maximum, mean or median, standard deviation, and number of determinations are given for each site for discharge,...
Reconnaissance geochemical exploration of the plutons of quartz monzonite and granite in the Jabal Lababa and Ar Rayth areas, southern Asir, Kingdom of Saudi Arabia
W.C. Overstreet, A.B. Assegaff, Mohammed Jambi, M.A. Hussain, G.I. Selner, J.J. Matzko
1985, Open-File Report 85-8
Geochemical reconnaissance for rare metals in plutons of albite-muscovite granite and quartz monzonite in the vicinity of Jabal Lababa disclosed positive geochemical anomalies for beryllium, tantalum, thorium, lanthanum, niobium, tin, yttrium, and zirconium. The low anomalous values for the rare metals in rocks and the short mechanical dispersion trains, seldom...
Index of ground-water quality data for Florida
P. R. Seaber, O.O. Williams
1985, Open-File Report 85-177
The Master Water Data Index of the U.S. Geological Survey contains records and information for 13,925 ground-water quality collection sites in Florida as follows: 2,180 active and 11,559 inactive well sites, and 39 active and 147 inactive spring sites. Ground-water quality data have been and are being collected at more...
