Plan for assessment of the occurrence, status, and distribution of volatile organic compounds in aquifers of the United States
W.W. Lapham, Saeid Tadayon
1996, Open-File Report 96-199
The occurrence of volatile organic compounds (VOCs) in water is of national concern because of their relatively high aqueous solubility, mobility, and persistence, because many are known or suspected carcinogens, because of their widespread use, and because they have been found in drinking-water supplies. Because of this national concern, VOCs...

Comparison of estimated and observed stormwater runoff for fifteen watersheds in west-central Florida, using five common design techniques
J.T. Trommer, J.E. Loper, K.M. Hammett, Georgia Bowman
1996, Open-File Report 96-129
Hydrologists use several traditional techniques for estimating peak discharges and runoff volumes from ungaged watersheds. However, applying these techniques to watersheds in west-central Florida requires that empirical relationships be extrapolated beyond tested ranges. As a result there is some uncertainty as to their accuracy. Sixty-six storms in 15 west-central Florida...

This map database, identified as Faults, lineaments, and earthquake epicenters digital map of the Pahute Mesa 30' X 60' quadrangle, Nevada, has been approved for release and publication by the Director of the USGS. Although this database has been subjected to rigorous review and is substantially complete, the USGS reserves...
Use of an ultra-clean sampling technique with inductively coupled plasma-mass spectrometry to determine trace-element concentrations in water from the Kirkwood-Cohansey Aquifer system, coastal plain, New Jersey
Tamara Ivahnenko, Zoltan Szabo, G.S. Hall
1996, Open-File Report 96-142
Water samples were collected during 1993 from 22 public supply wells screened in the Kirkwood-Cohansey aquifer system; concentrations of 18 trace elements were determined primarily by using inductively coupled plasma-mass spectrometry (ICP-MS) techniques, though graphite furnace atomic adsorption, hydride generation, and cold- vapor flameless atomic adsorption techniques were used for...
Selected geohydrologic data from a regional aquifer-system analysis of the Northern Rocky Mountains intermontane basins in Idaho
M.A. Stone, D. J. Parliman, J.L. Schaefer
1996, Open-File Report 96-207
The U.S. Geological Survey began a regional aquifer-system analysis of the Northern Rocky Mountains of northern and central Idaho and western Montana in 1990. The analysis helped establish a regional framework of information for aquifers in about 70 ntermontane basins in an area of 80,000 square miles. In many areas,...

Quality-assurance plan for water-resources activities of the U.S. Geological Survey in Idaho
F. A. Packard
1996, Open-File Report 95-755
To ensure continued confidence in its products, the Water Resources Division of the U.S. Geological Survey implemented a policy that all its scientific work be performed in accordance with a centrally managed quality-assurance program. This report establishes and documents a formal policy for current (1995) quality assurance within the Idaho...
Reconnaissance of volatile organic compounds in the subsurface at Rutgers University, Busch Campus, Piscataway Township, New Jersey
Vincent T. DePaul
1996, Open-File Report 95-729
During 1991-92, the U.S. Geological Survey conducted a hydrogeologic reconnaissance at a site near the Rutgers University, Busch Campus, Chemical Engineering building, C-Wing. Results of analyses of the soil-gas samples, which were collected at 43 locations, indicated the presence of volatile organic compounds, primarily carbon tetrachloride, near the C-Wing building...

Some facts about aftershocks to large earthquakes in California
Lucile M. Jones, Paul A. Reasenberg
1996, Open-File Report 96-266
Earthquakes occur in clusters. After one earthquake happens, we usually see others at nearby (or identical) locations. To talk about this phenomenon, seismologists coined three terms foreshock , mainshock , and aftershock. In any cluster of earthquakes, the one with the largest magnitude is called the mainshock; earthquakes that occur...

Water-quality processes in the Salt Creek watershed in northeastern Illinois were simulated with a computer model. Selected waste-load scenarios for 7-day, 10-year low-flow conditions were simulated in the stream system. The model development involved the calibration of the U.S. Environmental Protection Agency QUAL2E model to water-quality constituent concentration data collected...
