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
1996, Open-File Report 96-339
A map showing ground-water levels in crystalline and metasedimentary rocks in Valley and West Brandywine Townships, Chester County, Pennsylvania, was constructed from water levels measured in wells from May 1992 through August 1993. Pre-1992 measurements were incorporated on the map to provide control in areas where more recent data were...
Analysis of tests of subsurface injection, storage, and recovery of freshwater in the lower Floridan aquifer, Okeechobee County, Florida
Vicente Quinones-Aponte, Kevin Kotun, J. F. Whitley
1996, Open-File Report 95-765
A series of freshwater subsurface injection, storage, and recovery tests were conducted at an injection-well site near Lake Okeechobee in Okeechobee County, Florida, to assess the recoverability of injected canal water from the Lower Floridan aquifer. At the study site, the Lower Floridan aquifer is characterized as having four local,...
Tertiary igneous rocks and Laramide structure and stratigraphy of the Spanish Peaks Region, South-Central Colorado: Road log and descriptions from Walsenburg to La Veta
Brian S. Penn, D. A. Lindsay
1996, Open-File Report 96-04-28
The Spanish Peaks are located in the western part of the Raton basin in south-central Colorado, southwest of Walsenburg. The two peaks, West Spanish Peak (WSP, 13,626 feet) and East Spanish Peak (ESP, 12,683 feet), are located on the upland part of the far western edge of the Great Plains...
Hydrologic and water-quality data for two small watersheds on Catoctin Mountain, North-Central Maryland, 1987-93
Karen C. Rice, Margaret M. Kennedy, Christiana A. Carter, Robert T. Anderson, Owen P. Bricker
1996, Open-File Report 95-151
Hydrologic and water-quality data were collected from a precipitation-collection station and from two small watersheds on Catoctin Mountain, north-central Maryland, as part of investigations of acidic deposition and episodic acidification, and their effects on streamwater quality. Detailed descriptions of the site instrumentation in the watersheds, field data-collection techniques, and laboratory...
Characteristics of debris flows of noneruptive origin on Mount Shasta, northern California
James C. Blodgett, Karen R. Poeschel, Waite R. Osterkamp
1996, Open-File Report 96-144
Studies of Mount Shasta indicate that eruptive activity has occurred, on the average, once every 800 years. Debris flows and deposits of non- eruptive origin, in addition to those associated with eruptive activity (lava flows, pyroclastic flows, and ash fall), inundate the fans and channels and can endanger people or...
The Beaver Creek story
W.H. Doyle Jr., B.G. Whitworth, G.F. Smith, T.D. Byl
1996, Open-File Report 96-398
Beaver Creek watershed in West Tennessee includes about 95,000 acres of the Nation's most productive farmland and most highly erodible soils. In 1989 the U.S. Geological Survey, in cooperation with the Tennessee Department of Agriculture, began a study to evaluate the effect of agricultural activities on water quality in the...
Results of a seepage investigation at Bear Creek Valley, Oak Ridge, Tennessee, January through September 1994
J. A. Robinson, G.C. Johnson
1996, Open-File Report 95-459
A seepage investigation was conducted of 4,600 acres of Bear Creek Valley southwest of the Y-12 Plant, Oak Ridge, Tennessee, for the period of January through September 1994. The data were collected to help the Y-12 Environmental Restoration Program develop a better understanding of ground-water and surface-water interactions, recharge and...
Organochlorine compounds and trace elements in fish tissue and ancillary data for the Connecticut, Housatonic, and Thames river basins study unit, 1992-94
J.F. Coles
1996, Open-File Report 96-358
Concentrations of organochlorine compounds and trace elements were assayed in fish tissue collected from the Connecticut, Housatonic, and Thames River Basins Study Unit, 1992-94. These data were collected to determine the occurrence and distribution of organochlorine compounds and trace elements in the study unit. Ancillary data included are land-use categories...
Analysis of selected water-quality data for surface water in St. Tammany Parish, Louisiana, April-August 1995
Dennis K. Demcheck
1996, Open-File Report 96-345
Physical and chemical-related properties, concentrations of chemical constituents, which included major ions and nutrients, and concentrations of fecal-coliform bacteria were determined for 17 sites on 11 streams in St. Tammany Parish, Louisiana, during the period April-August 1995. The streams were sampled to assess the effects of different streamflow conditions...
