Work plan for the Schuylkill River basin, Pennsylvania: Assessment of river quality as related to the distribution and transport of trace metals and organic substances
G.L. Pederson, Thomas H. Yorke, J. K. Stamer
1980, Open-File Report 80-566
The U.S. Geological Survey is making a river-quality assessment of the Schuylkill River basin in Pennsylvania from October 1978 to March 1981. It is part of a continuing program designed to demonstrate the effectiveness of river-quality studies for basin planning and water-resource management. Study objectives include determining (1) presence of...
Hydrologic data for urban studies in the San Antonio, Texas, metropolitan area, 1977
Roberto Perez, Lynn Harmsen
1980, Open-File Report 80-743
Hydrologic investigations of urban drainage basins in Texas were begun by the U.S. Geological Survey in 1954. These studies are now in progress in Austin, Dallas, Dallas County, Fort Worth, Houston, and San Antonio.The Geological Survey, in cooperation with the Texas Department of Water Resources, expanded the existing gaging-station network...
Rapid and precise determination of ATP using a modified photometer
David J. Shultz, Doyle W. Stephens
1980, Open-File Report 80-1194
An inexpensive delay timer was designed to modify a commercially available ATP photometer which allows a disposable tip pipette to be used for injecting either enzyme or sample into the reaction cuvette. The disposable tip pipette is as precise and accurate as a fixed-needle syringe but eliminates the problem of...
Ground-water availability on the Kitsap Peninsula, Washington
Arnold J. Hansen Jr., E.L. Bolke
1980, Open-File Report 80-1186
Unconsolidated deposits on the Kitsap peninsula are of glacial and interglacial origin. These deposits were divided into three units on the basis of their lithology and hydraulic properties. Two of the three units are composed of layers of sand and gravel alternating with layers of silt and clay. The third...

Water resources data for Alabama, water year 1979; Volume 1, Apalachicola, Choctawatchee, Blackwater, Escambia, Perdido, and Alabama River basins
Water Resources Division, U.S. Geological Survey
1980, Water Data Report AL-79-1
Water resources data for the 1979 water year consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report contains records for water discharge at 48 gaging stations; stage only at 16...
Examples of the use of earth-science information by decisionmakers in the San Francisco Bay region, California
W. J. Kockelman
1980, Open-File Report 80-124
In the six examples discussed and illustrated here, innovative decisionmakers -- public and private -- have used earth-science information to avoid areas with geologic hazards, protect natural resources, and reduce possible property damage in the San Francisco Bay region. The examples show how: 1) development in fault-rupture areas is regulated,...
