Hydrologic data for Long Valley Caldera, Mono County, California, 1987-93
J. F. Howle, C. D. Farrar
1996, Open-File Report 96-382
Hydrologic data were collected during 1987-93 as part of the U.S. Geological Survey's long-term Volcanic Hazards Monitoring Program of the Long Valley Caldera, Mono County, California. The data are presented in graphs or tables. Data collected for the Long Valley Hydrologic Advisory Committee monitoring program also are presented. Hydrologic data...
Snowpack chemistry at selected sites in northwestern Colorado during spring 1995
G.P. Ingersoll
1996, Open-File Report 96-411
Samples of the alpine and subalpine snowpack were collected in and near the headwater basins of the Yampa River in northwestern Colorado during maximum annual accumulation of snowpack in spring 1995. Sampling protocol at seven selected sites at more than 2,500 meters above sea level divided the snowpack into two...
Analysis of hydrogeologic properties in the Prairie du Chien-Jordan aquifer, Shakopee Mdewakanton Sioux Community, southeastern Minnesota
M.L. Strobel, G. N. Delin
1996, Open-File Report 96-182
The Prairie du Chien-Jordan aquifer is a major source of water for many communities in southeastern Minnesota. The water-supply well for the Shakopee Mdewakanton Sioux Community derives water from the Jordan part of the aquifer. An aquifer test in the Prairie du Chien-Jordan aquifer in the area of the Shakopee...
Urban land-use study plan for the National Water-Quality Assessment Program
P. J. Squillace, C. V. Price
1996, Open-File Report 96-217
This study plan is for Urban Land-Use Studies initiated as part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. There are two Urban Land-Use Study objectives: (1) Define the water quality in recharge areas of shallow aquifers underlying areas of new residential and commercial land use in large...
Geohydrology and potential for upward movement of saline water in the Cocoa well field, East Orange County, Florida
G. G. Phelps, D. M. Schiffer
1996, Open-File Report 95-736
The Floridan aquifer system, an approximately 2,000-foot thick sequence of Eocene-age limestone and dolomite, is the main source of water supply in central Florida. Hydraulic conductivity is different in strata of different lithology and is the basis for separating the aquifer system into the Upper Floridan aquifer, a middle semi-...
Water-quality, bed-sediment, and biological data (October 1994 through September 1995) and statistical summaries of data for streams in the upper Clark Fork basin, Montana
K. A. Dodge, Michelle I. Hornberger, E.V. Axtmann
1996, Open-File Report 96-432
Water, bed sediment, and biota were sampled in streams from Butte to below Missoula as part of a program to characterize aquatic resources in the upper Clark Fork basin of western Montana. Sampling stations were located on the Clark Fork and major tributaries. Water-quality data were obtained periodically at 16...
Status of ground-water resources at U.S. Navy Support Facility, Diego Garcia; summary of hydrologic and climatic data, January 1994 through June 1996
J.D. Torikai
1996, Open-File Report 96-438
This report describes the status of ground-water resources at U.S. Navy Support Facility, Diego Garcia. Data presented are from January 1994 through June 1996, with a focus on data from April through June 1996 (second quarter of 1996). A complete database of ground-water withdrawals and chloride-concentration records since 1985 is...
Selected meteorological and micrometeorological data for an arid site near Beatty, Nye County, Nevada, calendar year 1992
James L. Wood
1996, Open-File Report 96-434
il-heat-flux data were collected at a study site adjacent to a low-level radioactive-waste burial facility near Beatty, Nevada, for calendar year 1992. Data were collected in support of ongoing studies to estimate the potential for downward movement of radionuclides into the unsaturated sediments beneath waste-burial trenches at the arid facility....
Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of pesticides in water by Carbopak-B solid-phase extraction and high-preformance liquid chromatography
Stephen L. Werner, Mark R. Burkhardt, Sabrina N. DeRusseau
1996, Open-File Report 96-216
In accordance with the needs of the National Water-Quality Assessment Program (NAWQA), the U.S. Geological Survey has developed and implemented a graphitized carbon-based solid-phase extraction and high-performance liquid chromatographic analytical method. The method is used to determine 41 pesticides and pesticide metabolites that are not readily amenable to gas chromatography...
Geologic history and hydrogeologic units of intermontane basins of the northern Rocky Mountains, Montana and Idaho
L.K. Tuck, David W. Briar, David W. Clark
1996, Hydrologic Atlas 738-A
The Regional Aquifer-System Analysis (RASA) program is a series of studies by the U.S. Geological Survey (USGS) to analyze regional ground-water systems that compose a major portion of the Nation’s water supply (Sun, 1986). The Northern Rocky Mountains Intermontane Basins is one of the study regions in this national program....
Altitude and configuration of the potentiometric surface, December 6, 1994, in the carbonate rocks in part of East Whiteland and Charlestown townships, Chester County, Pennsylvania
B. C. McManus, R. A. Sloto
1996, Open-File Report 96-367
A map showing ground-water levels in the carbonate rocks in part of East Whiteland and Charlestown Townships, Chester County, Pennsylvania, was constructed from water levels measured in 64 wells on December 6, 1994. Observed water-level altitudes range from 226 feet above sea level near Morehall Road to 400 feet above...
Altitude and configuration of the potentiometric surface in the crystalline and metasedimentary rocks in Valley and West Brandywine townships, Chester County, Pennsylvania, May 1992 through August 1993
J.E. McGovern, April Bossert, W.C. Wettstein
