Screening for volatile organic compounds in soil and groundwater by use of a portable gas chromatograph during field investigations at an Air Force installation in Ohio
James M. Parnell
1995, Open-File Report 95-371
The use of the portable gas chromatograph for screening of soil and water samples in the field was part of the drilling program for the installation of monitoring wells for a basewide ground-water monitoring program at Wright-Patterson Air Force Base, Ohio. Selected soil and ground-water samples were screened in the...
Nutrients in ground water and surface water of the United States; an analysis of data through 1992
D. K. Mueller, P. A. Hamilton, D.R. Helsel, K.J. Hitt, B. C. Ruddy
1995, Water-Resources Investigations Report 95-4031
Historical data on nutrient (nitrogen and phosphorus species) concentrations in ground-and surface-water samples were compiled from 20 study units of the National Water-Quality Assessment (NAWQA) Program and 5 supplemental study areas. The resultant national retrospective data sets contained analyses of about 12,000 Found-water and more than 22,000 surface-water samples. These...
A workbook for preparing surface water quality-assurance plans for districts of the U.S. Geological Survey, Water Resources Division
Donald V. Arvin
1995, Open-File Report 94-382
The U.S. Geological Survey, Water Resources Division, has a policy that each District Office is required to prepare a District Surface Water Quality-Assurance Plan. The plan for each District describes the policies and procedures that ensure high quality in the collection, processing, analysis, computer storage, and publication of surface-water data....
Vulnerability of the uppermost ground water to contamination in the greater Denver area, Colorado
G. A. Hearne, Michael Wireman, A.S. Campbell, Sandy Turner, G.P. Ingersoll
1995, Water-Resources Investigations Report 92-4143
Information about vulnerability of ground water to contamination is needed to facilitate ground-water management. Vulnerability of ground water refers to the intrinsic characteristics that determine the sensitivity of the water to being adversely affected by an imposed contaminant load. Within the greater Denver area, vulnerability of the uppermost ground water...
Data on ground-water levels and ground-water/surface-water relations in the Great Miami River and Little Miami River valleys, southwestern Ohio
William P. Yost
1995, Open-File Report 95-357
Hydrogeologic data were collected in September, October, and November 1993 to define the ground-water levels and the ground-water/surface-water relations in the vicinity of Dayton, Ohio. In this report, water levels are listed for 678 wells completed in sand and gravel. Data from 101 streamflow measurements made at selected sites along...
Analytical data from phases I and II of the Willamette River basin water quality study, Oregon
Howard E. Harrison, Chauncey W. Anderson, Frank A. Rinella, Timothy M. Gasser, Ted R. Pogue Jr.
1995, Open-File Report 95-373
This report presents trace-element, organic-compound (pesticides, volatile and semivolatile organic compounds, and dioxin and furan compounds), and nutrient concentration data from the analyses of water column, suspended-sediment, and bed-sediment samples collected by the U.S. Geological Survey as part of Phases I and II of the comprehensive Willamette River Basin Water...
U.S. Geological Survey activities in New Mexico 1995
Russell K. Livingston
1995, Open-File Report 95-314
The report provides an overview of the USGS in New Mexico, including activities of the Water Resources, Geologic, and National Mapping Divisions. Some USGS projects address hydrologic and geologic hazards, such as flood discharges, landslides, and land subsidence. Recent environmental assessments include participation in the Kirtland Air Force Base Installation...
Areal distribution of selected trace elements, salinity, and major ions in shallow ground water, Tulare Basin, Southern San Joaquin Valley, California
Roger Fujii, Walter C. Swain
1995, Water-Resources Investigations Report 95-4048
The distribution of salinity and selected trace elements in shallow ground water in the Tulare Basin, California, was assessed to evaluate potential problems related to disposal in evaporation ponds of irrigation drain water containing elevated concentrations of selenium and other trace elements. The constituents of primary concern were selenium, arsenic,...
Hydrogeologic and agricultural-chemical data for the South Skunk River alluvial aquifer at a site in Story County, Iowa, 1992-93
Robert C. Buchmiller
1995, Water-Resources Investigations Report 94-4244
A reconnaissance study was conducted during 1992-93 to collect background hydrogeologic and agricultural-chemical data for the South Skunk River alluvial aquifer near Ames, Iowa. Observation wells were drilled to characterize the surficial geologic materials of a field-scale study site and to provide locations for collecting waterlevel and agricultural-chemical data. Walnut...
Water-quality assessment of the Albemarle-Pamlico drainage basin, North Carolina and Virginia environmental setting and water-quality issues
Gerard McMahon, Orville B. Lloyd
1995, Open-File Report 95-136
The Albemarle-Pamlico drainage study unit is one of 60 units of the U.S. Geological Survey's National Water-Quality Assessment Program, and includes the large river basins which drain into the Albemarle and Pamlico Sounds-the Chowan, Roanoke, Tar-Pamlico, and Neuse River Basins. The study unit includes about 28,000 square miles and has...
Flood-frequency relations for urban streams in Georgia; 1994 update
Ernest J. Inman
1995, Water-Resources Investigations Report 95-4017
A statewide study of flood magnitude and frequency in urban areas of Georgia was made to develop methods of estimating flood characteristics at ungaged urban sites. A knowledge of the magnitude and frequency of floods is needed for the design of highway drainage structures, establishing flood- insurance rates, and other...
Relation of fracture orientation to linear terrain features, anisotropic transmissivity, and seepage to streams in the karst Prairie du Chien Group, southeastern Minnesota
J. F. Ruhl
1995, Water-Resources Investigations Report 94-4146
Ground-water flow in the karst-terrane aquifers of southeastern Minnesota is not well defined. Variable fracture patterns in the bedrock affect permeability. Techniques to predict the effects of fracture patterns on ground-water flow in the karst-terrane aquifers of southeastern Minnesota are unavailable. The use of such techniques may be useful to...
