Geohydrologic reconnaissance of a ground-water contamination problem in the Argonne Road area near Spokane, Washington
N. P. Dion
1987, Water-Resources Investigations Report 86-4173
Three domestic wells that withdraw groundwater from an alluvium-filled trough cut into granite were found to be contaminated with the organic solvents tetrachloroethene, trichloroethene, 1,1,1-trichloroethane, and 1 ,2-trans-dichloroethene. The suspected source of contamination is a nearby septic-tank sludge disposal area. There is concern that the affected aquifer is tributary to...

1987, Open-File Report 84-734
This report is one of a series designed to characterize the hydrology of drainage basins within coal provinces, nationwide. Area 51 (in the Rocky Mountain Coal Province) includes all or part of the Shoshone, Bighorn, Greybull, Wind, and Popo Agie River drainage basins - a total of 11,800 sq mi....
Relation of water chemistry of the Edwards aquifer to hydrogeology and land use, San Antonio Region, Texas
Paul M. Buszka
1987, Water-Resources Investigations Report 87-4116
Water-chemistry data from the Edwards aquifer for 1976-85, consisting of nearly 1,500 chemical analyses from 280 wells and 3 springs, were used to statistically evaluate relations among ground-water chemistry, hydrogeology, and land use. Five land uses associated with sampled wells were classified on the basis of published information and field...

James Frank Williams III, W.B. Lind, L.S. Coplin
1987, Open-File Report 87-233
The purpose of this report, which was prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District, is to show the altitudes of water levels in wells in the Chicot and Evangeline aquifers in the Houston, Texas, metropolitan area.  The maps are based on water-level measurements...
Bibliography of U.S. Geological Survey reports on the water resources of Florida, 1886-1986
Maude Claiborne, T.L. Embry, N.D. Hoy, D.H. Weldon, T.D. Wilson
1987, Open-File Report 85-424
The U.S. Geological Survey has released a listing of its report on water resources in Florida for the period 1886-1984. Most of the reports contained in the listing were prepared by the U.S. Geological Survey in cooperation with numerous public agencies in Florida. The compilation has a full bibliographic list...
Chemical characteristics of water in the surficial aquifer system, Dade County, Florida
W. H. Sonntag
1987, Water-Resources Investigations Report 87-4080
Geohydrologic test drilling was conducted throughout Dade County to describe the chemical characteristics of water from geohydrologic units in the surficial aquifer system. Water quality analysis of samples collected from the test wells completed in central Dade County indicates that the Biscayne aquifer (unit A), the upper clastic unit of...
Sensitivity analysis of a multilayer, finite-difference model of the southeastern Coastal Plain regional aquifer system: Mississippi, Alabama, Georgia, and South Carolina
Meribeth Pernik
1987, Water-Resources Investigations Report 87-4108
The sensitivity of a multilayer finite-difference regional flow model was tested by changing the calibrated values for five parameters in the steady-state model and one in the transient-state model. The parameters that changed under the steady-state condition were those that had been routinely adjusted during the calibration process as part...
Description of the physical environment and coal-mining history of west-central Indiana, with emphasis on six small watersheds
Jeffrey D. Martin, Charles G. Crawford, R.F. Duwelius, D.E. Renn
1987, Open-File Report 87-212
Information on the geology, geomorphology, soils, climate, hydrology, water use, land use, population, and coal mining history of Clay, Owen, Sullivan, and Vigo Counties in Indiana is summarized. Site-specific information is given on the morphology , geology, soils, land use, coal mining history, and hydrologic instrumentation of the six watersheds...
Evaluation of selected surface-water-quality stations in Wyoming
S.J. Rucker, L. L. DeLong
1987, Water-Resources Investigations Report 82-4003
The U.S. Geological Survey, in cooperation with the Wyoming Department of Agriculture, has conducted a surface-water-quality program in Wyoming since 1965. The purpose has been to determine the chemical quality of the water in terms of the major dissolved constituents (salinity). Changing agricultural techniques and energy development have stimulated a...
Evapotranspiration and microclimate at a low-level radioactive-waste disposal site in northwestern Illinois
R. W. Healy, M.P. DeVries, A.M. Sturrock
1987, Open-File Report 86-301
From July 1982 through June 1984, a study was made of the microclimate and evapotranspiration at a low-level radioactive-waste disposal site near Sheffield, Bureau County, Illinois. Vegetation at the site consists of mixed pasture grasses, primarily brome (Bromus inermis) and red clover (Trifoleum pratense). Three methods were used to estimate...
Overview of water resources in Owens Valley, California
L.S. Rogers
1987, Water-Resources Investigations Report 86-4357
In 1982-84, a water resources appraisal of Owens Valley was made by using available hydrologic information. Results of the appraisal provided an overview of water resources in Owens Valley; a better understanding of the groundwater system; and a framework for additional studies. Owens Valley is in east-central California and is...
