Geohydrology of alluvium and terrace deposits of the Cimarron River from freedom to Guthrie, Oklahoma
G. P. Adams, D. L. Bergman
1996, Water-Resources Investigations Report 95-4066
Ground water in 1,305 square miles of Quaternary alluvium and terrace deposits along the Cimarron River from Freedom to Guthrie, Oklahoma, is used for irrigation, municipal, stock, and domestic supplies. As much as 120 feet of clay, silt, sand, and gravel form an unconfined aquifer with an average saturated thickness...
Sediment magnetic, paleomagnetic, and geochemical data from Quaternary lacustrine sediment in a core from Grass Lake, Siskiyou County, California
Patti J. Best, Richard L. Reynolds, Joseph G. Rosenbaum, John W. Drexler, David P. Adam
1996, Open-File Report 96-294
Sediment magnetic and geochemical results have been obtained from the top 60 meters of lacustrine sediments recovered in two cores from Tule Lake in northern California. The sediment magnetic and geochemical data, presented here in tabular form, complement studies of diatoms and pollen in the cores that are the bases...
Sediment magnetic and geochemical data from Quaternary lacustine sediment in two cores from Tule Lake, Siskiyou County, California

1996, Open-File Report 96-293
Sediment magnetic and geochemical results have been obtained from the top 60 meters of lacustrine sediments recovered in two cores from Tule Lake in northern California. The sediment magnetic and geochemical data, presented here in tabular form, complement studies of diatoms and pollen in the cores that are the bases...
Explanation of fields used in the Alaska Resource Data File of mines, prospects, and mineral occurrences in Alaska
Water Resources Division, U.S. Geological Survey
1996, Open-File Report 96-79
Descriptions of mines, prospects, and mineral occurrences in the Alaska Resource Data File (ARDF) are published for individual U.S. Geological Survey 1:250,000 scale quadrangles in Alaska (see accompanying map) and are available for downloading from USGS World Wide Web site: http://www-rnrs-ak.wr.usgs.gov/ardf.These descriptions are divided into a number of...
Sublake geologic structure from high-resolution seismic-reflection data from four sinkhole lakes in the Lake Wales Ridge, central Florida
A. B. Tihansky, J. D. Arthur, D.W. DeWitt
1996, Open-File Report 96-224
Seismic-reflection profiles from Lake Wales, Blue Lake, Lake Letta, and Lake Apthorp located along the Lake Wales Ridge in central Florida provide local detail within the regional hydrogeologic framework as described by litho- and hydrostratigraphic cross sections. Lakes located with the mantled karst region have long been considered to be...
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...
Prediction of traveltime and longitudinal dispersion in rivers and streams
Harvey E. Jobson
1996, Water-Resources Investigations Report 96-4013
The possibility of a contaminant being accidentally or intentionally spilled upstream from a water supply is a constant concern to those diverting and using water from streams and rivers. Although many excellent models are available to estimate traveltime and dispersion, none can be used with confidence before calibration and verification...
Numerical Analysis of Ground-Water Flow and Salinity in the Ewa Area, Oahu, Hawaii
Delwyn S. Oki, William R. Souza, Edward I. Bolke, Glenn R. Bauer
1996, Open-File Report 96-442
The coastal plain in the Ewa area of southwestern Oahu, Hawaii, is part of a larger, nearly continuous sedimentary coastal plain along Oahu's southern coast. The coastal sediments are collectively known as caprock because they impede the free discharge of ground water from the underlying volcanic aquifers. The caprock is...
Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-In-bottle acid digestion of whole-water samples
G. L. Hoffman, M. J. Fishman, J.R. Garbarino
1996, Open-File Report 96-225
Water samples for trace-metal determinations routinely have been prepared in open laboratories. For example, the U.S. Geological Survey method I-3485-85 (Extraction Procedure, for Water- Suspended Sediment) is performed in a laboratory hood on a laboratory bench without any special precautions to control airborne contamination. This method tends to be contamination...
A seepage investigation of an area at and near Oak Ridge National Laboratory, Oak Ridge, Tennessee, March through August 1993
G.C. Johnson
1996, Open-File Report 95-442
A seepage investigation was conducted of an area surrounding the Oak Ridge National Laboratory from March through August 1993. The project was divided into three phases: a reconnaissance to inventory and map seeps, springs, and stream-measurement sites; a high base flow seepage investigation; and a low base flow seepage investigation....
Construction, lithologic, and water-level data for wells near the Dickson County landfill, Dickson County, Tennessee, 1995
D.E. Ladd
1996, Open-File Report 96-229
Organic compounds were detected in water samples collected from Sullivan Spring during several sampling events in 1994. Prior to this, the spring was the drinking-water source for two families in the Dickson, Tennessee area. An investigation was conducted by the U.S. Geological Survey, in cooperation with Dickson County Solid Waste...
Altitude and configuration of the potentiometric surface in the crystalline and metasedimentary rocks in Birmingham, Newlin, Pennsbury, and Pocopson Townships and parts of East Marlborough and Kennett Townships, Chester County, Pennsylvania, June 1994 through November 1995
Charles R. Wood, William C. Wettstein, Stephen S. Aichele, James Joyce, Frank M. Schneider
1996, Open-File Report 96-336
A map showing ground-water levels in crystalline and metasedimentary rocks in Birmingham, Newlin, Pennsbury, and Pocopson Townships and parts of East Marlborough and Kennett Townships, Chester County, Pennsylvania, was constructed from water levels measured in wells from June 1994 through November 1995. Pre-1994 measurements were incorporated on the map to...

Pre-1993 measurements were incorporated on the map to provide control in areas where more recent...
Surface-water quality assessment of the Clover Creek basin, Pierce County, Washington, 1991-92
K. A. McCarthy
1996, Water-Resources Investigations Report 95-4181
Increasing urbanization in the 67-square-mile Clover Creek Basin has generated interest in the effects of land-use changes on local water quality. To investigate these effects, water-quality and streamflow data were collected from 19 surface-water sites in the basin over a 16-month period from January 1991 through April 1992. These data...
