Water-quality, bed-sediment, and biological data (October 1993 through September 1994) and statistical summaries of data for streams in the Upper Clark Fork basin, Montana
J. H. Lambing, Michelle I. Hornberger, E.V. Axtmann, K. A. Dodge
1995, Open-File Report 95-429
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. Water- quality data were obtained periodically at 16 stations during October 1993 through September 1994 (water year 1994);...
Mercury contamination of aquatic ecosystems
David P. Krabbenhoft, David A. Rickert
1995, Fact Sheet 216-95
Mercury has been well known as an environmental pollutant for several decades. As early as the 1950's it was established that emissions of mercury to the environment could have serious effects on human health. These early studies demonstrated that fish and other wildlife from various ecosystems commonly attain mercury levels...
Reversal of declining ground-water levels in the Chicago area
Charles Avery
1995, Fact Sheet 222-95
Abundant water resources have been an important part of the economic development of the Chicago area for more than a century. The city of Chicago, Ill., and other lakefront towns have used Lake Michigan as a water supply. Where water from Lake Michigan was not available or a need for supplemental...
Geohydrology and water quality of stratified-drift aquifers in the Saco and Ossipee River basins, east-central New Hampshire
R. B. Moore, Laura Medalie
1995, Water-Resources Investigations Report 94-4182
Stratified-drift aquifers discontinuously underlie 152.5 square miles of the Saco and Ossipee River Basins, which have a total drainage area of 869.4 square miles. Saturated thicknesses of stratified drift in the study area are locally greater than 280 feet, but generally are less. Transmissivity locally exceeds 8,000 feet squared per...
Processes controlling dissolved oxygen and pH in the upper Willamette River basin, Oregon, 1994
Ted R. Pogue Jr., Chauncey W. Anderson
1995, Water-Resources Investigations Report 95-4205
In July and August of 1994, the U. S. Geological Survey in cooperation with the Oregon Department of Environmental Quality (ODEQ) collected data to document the spatial extent and diel variability of dissolved oxygen (DO) concentrations and pH levels in selected reaches of streams in the upper Willamette River Basin....
Bibliography, indices, and data sources of water-related studies, upper Colorado River basin, Colorado and Utah, 1872-1995
N.J. Bauch, L.E. Apodaca
1995, Open-File Report 95-450
As part of the U.S. Geological Survey's National Water-Quality Assessment Program, current water-quality conditions in the Upper Colorado River Basin in Colorado and Utah are being assessed. This report is an initial effort to identify and compile information on water-related studies previously conducted in the basin and consists of a...
Water levels in the Calumet aquifer and their relation to surface-water levels in northern Lake County, Indiana, 1985-92
Theodore K. Greeman
1995, Water-Resources Investigations Report 94-4110
The U.S. Geological Survey made 2,328 water-level measurements at a total of 96 ground-water and surface-water sites in northern Lake County, Indiana, from August 1985 through September 1992. This report lists and summarizes the significance of the measurements. Northern Lake County is on the southern shore of Lake Michigan and...
Geohydrology and water quality of the Durham Center Area, Durham, Connecticut
R.L. Melvin, J. R. Stone, P. A. Craft, J.W. Lane Jr., B.S. Davies III
1995, Water-Resources Investigations Report 94-4237
Contaminated ground water is widespread and persistent beneath the Durham Center area in the town of Durham, Conn. Most of the contaminants are organic halides, usually trichloroethene, 1,1,1-trichloroethane, and tetrachloroethene. Less extensive chemical contamination of surface water, soil, and glacial sediments also has been detected. Two manufacturing companies, located at...
Numerical Simulation of Regional Changes in Ground-Water Levels and in the Freshwater-Saltwater Interface Induced by Increased Pumpage at Barbers Point Shaft, Oahu, Hawaii
William R. Souza, William Meyer
1995, Water-Resources Investigations Report 95-4206
The effect on the regional ground-water system of southern Oahu from increased pumpage at Barbers Point shaft was estimated by a numerical ground-water model developed for the Oahu Regional Aquifer Systems Analysis (RASA) study. The RASA model was updated by revising pumping and ground-water recharge data. Pumpage data used in...
Some fluid-inclusion measurements for geothermal drill holes in California, Nevada, El Salvador, and Russia
Keith E. Bargar
1995, Open-File Report 95-826
The purpose of this report is to make available fluid-inclusion information from drill holes in five geothermal areas: The Geysers and Long Valley caldera in northern California; Steamboat Springs, Nevada; the Ahuachapan field of El Salvador, Central America; and the Mutnovsky geothermal field, Kamchatka Peninsula, Russia. These data were produced...
