Hydrogeology and water quality in the Graces Quarters area of Aberdeen Proving Ground, Maryland
Frederick J. Tenbus, Joel D. Blomquist
1995, Water-Resources Investigations Report 94-4175
Graces Quarters was used for open-air testing of chemical-warfare agents from the late 1940's until 1971. Testing and disposal activities have resulted in the contamination of ground water and surface water. The hydrogeology and water quality were examined at three test areas, four disposal sites, a bunker, and a service...
Hydrology of Laguna Joyuda, Puerto Rico

1995, Water-Resources Investigations Report 93-4135
A study was conducted by the U.S. Geological Survey to define the hydraulic and hydrologic characteristics of the Laguna Joyuda system (in southwestern Puerto Rico) and to determine the water budget of the lagoon. This shallow-water lagoon is connected to the sea by a single canal. Rainfall and evaporation, surface-water,...

Precision of a splitting device for water samples
Paul D. Capel, Fernando C. Nacionales, Steven J. Larson
1995, Open-File Report 95-293
Two identical cone splitters, devices designed to split water and its suspended solids into equal aliquots for semi-volatile organic chemical and trace element analyses, were evaluated for their precision. The water-splitting evaluations consisted of experiments to test the effect of water volume, the effect of combining outlet ports, and the...

Hydrogeology of the Cascade Springs area near Tullahoma, Tennessee
S.E. Johnson
1995, Water-Resources Investigations Report 95-4002
The ground-water-flow system contributing to Cascade Springs near Tullahoma, Tennessee, was investigated from September 1991 to May 1992. Cascade Springs, consisting of Left Cascade and Right Cascade Springs, are located on the escarpment of the Highland Rim and discharge immediately above the Chattanooga Shale from the cherty Fort Payne Formation....
Computation of bedrock-aquifer recharge in northern Westchester County, New York, and chemical quality of water from selected bedrock wells
Stephen W. Wolcott, Robert F. Snow
1995, Water-Resources Investigations Report 92-4157
An empirical technique was used to calculate the recharge to bedrock aquifers in northern Westchester County. This method requires delineation of ground-water divides within the aquifer area and values for (1) the extent of till and exposed bedrock within the aquifer area, and (2) mean annual runoff. This report contains...

1995, Water-Resources Investigations Report 94-4086
The U.S. Geological Survey is conducting an assessment of water quality in the Trinity River Basin as part of the National Water-Quality Assessment Program. During the planning phase of this study, existing information on nutrients and suspended sediment was compiled and analyzed. A total of about 5,700 water-quality samples were...
The surface of crystalline basement, Great Valley and Sierra Nevada, California: A digital map database

1995, Open-File Report 95-96
Crystalline basement in central California extends westward from the exposed Sierra Nevada beneath the sedimentary fill of the Great Valley and under the eastern edge of the Coast Ranges at mid-crustal depth. The surface of this basement is defined from three types of control: in the Sierra Nevada from the...
Potentiometric surface of the Sparta and Memphis aquifers in eastern Arkansas, April through July 1993
