Application of ground-penetrating radar methods in determining hydrogeologic conditions in a karst area, west-central Florida
G. L. Barr
1993, Water-Resources Investigations Report 92-4141
Ground-penetrating radar (GPR) is useful as a surface geophysical method for exploring geology and subsurface features in karst settings. Interpretation of GPR data was used to infer lithology and hydrogeologic conditions in west-central Florida. This study demonstrates how GPR methods can be used to investigate the hydrogeology of an area....

1993, Water-Resources Investigations Report 93-4201
Water from 11 wells completed in the Snake River Plain aquifer at the Idaho National Engineering Laboratory was sampled as part of the U.S. Geological Survey's quality assurance program to determine the effect of purging different borehole volumes on tritium and strontium-90 concentrations. Wells were selected for sampling on the...

1993, Water-Resources Investigations Report 93-4024
Data on streamflow, water quality, and macroinvertebrate and smallmouth bass (microptercus dolomieni) populations were collected from July 1987 through September 1990, in four streams in southwestern Wisconsin to determine the effect of surface-water hydrology and quality on populations of macroinvertebrates and smallmouth bass. The study was a joint project of...
Hydrogeology of glacial deposits in a preglacial bedrock valley, Waukesha County, Wisconsin

This report describes the areal extent, thickness, and hydraulic properties of glacial deposits in a preglacial bedrock valley south of the city of Waukesha in southeastern Wisconsin. In the 40- square-mile study area, the preglacial bedrock valley underlies an area across which the Fox River flows. A previous regional study...

Effects of well discharges on hydraulic heads in and spring discharges from the geothermal aquifer system in the Bruneau area, Owyhee County, southwestern Idaho
Charles Berenbrock
1993, Water-Resources Investigations Report 93-4001
Demand for ground water in the 600- square-mile Bruneau study area has increased since 1954 because of agricultural development. Declining flow at Indian Bathtub Spring is adversely affecting a unique species of snail that inhabits the spring. The Bruneau study area is underlain by sedimentary and volcanic rocks that form a...

1993, Water-Resources Investigations Report 93-4014
Results of a detailed study by the National Irrigation Water-Quality Program (NIWQP), U.S. Department of the Interior, indicate that factors controlling contaminant concentrations in subsurface irrigation drainwater in the Imperial Valley are soil characteristics, hydrology, and agricultural practices. Higher contaminant concentrations commonly were associated with clayey soils, which retard the...
Ground-water quality near an inactive landfill and sludge-spreading area, Tallahassee, Florida
M. P. Berndt
1993, Water-Resources Investigations Report 93-4027
Ground-water quality of a 120-acre area encompassing an inactive landfill southwest of Tallahassee, Florida, was assessed by installing and sampling 21 monitoring wells. Sludge from a municipal sewage-treatment plant was also applied to the land surface near the landfill site. Water samples were collected from the 21 monitoring wells from...

1993, Water-Resources Investigations Report 93-4087
Upper Klamath Lake, and the connecting Agency Lake, is a large (140 square mile) lake in south-central Oregon. The lake has a recent history of long-duration, near-monoculture, blue-green algal blooms of Aphanizomenon flos-aquae. Typically, the algal bloom causes nuisance and detrimental conditions, including a deep-green "pea soup" appearance, from mid-May...
