Summary of national standards and guidelines for pesticides in water, bed sediment, and aquatic organisms and their application to water-quality assessments
Lisa H. Nowell, Elizabeth A. Resek
1994, Open-File Report 94-44
Current (1993) national standards and guidelines pertaining to pesticide contaminants in water, bed sediment, and fish and shellfish tissues are summarized to provide a condensed reference source for definitions and current values applicable to pesticides in aquatic environmental media. This report facilitates comparison of measured concen- trations of pesticides in...
Petrophysical analysis of geophysical logs of the National Drilling Company-U.S. Geological Survey ground-water research project for Abu Dhabi Emirate, United Arab Emirates
Donald G. Jorgensen, Mario Petricola
1994, Water Supply Paper 2417
A program of borehole-geophysical logging was implemented to supply geologic and geohydrologic information for a regional ground-water investigation of Abu Dhabi Emirate. Analysis of geophysical logs was essential to provide information on geohydrologic properties because drill cuttings were not always adequate to define lithologic boundaries. The standard suite of logs...
Stable isotopes of hydrogen and oxygen in surface water and ground water at selected sites on or near the Idaho National Engineering Laboratory, Idaho
D.S. Ott, L.D. Cecil, L.L. Knobel
1994, Open-File Report 94-55
Relative stable isotopic ratios for hydrogen and oxygen compared to standard mean ocean water are presented for water from 4 surface-water sites and 38 ground-water sites on or near the Idaho National Engineering Laboratory (INEL). The surface-water samples were collected monthly from March 1991 through April 1992 and after a...
Development and documentation of spatial data bases for the Lake Tahoe Basin, California and Nevada
Kenn D. Cartier, Lorri A. Peltz, J. LaRue Smith
1994, Water-Resources Investigations Report 93-4182
A set of spatial data bases consisting of natural- resources and planimetric-base layers has been developed and documented for the Lake Tahoe Basin, California and Nevada. The data bases, in the form of geographic information system coverages, include surface geology, soils, timber type, riparian vegetation, land capability, stream channels, water...
Pathology of sea otters
T.P. Lipscomb, Richard K. Harris, A.H. Rebar, Brenda E. Ballachey, Romona J. Haebler
Thomas R. Loughlin, editor(s)
1994, Book chapter, Marine mammals and the <i>Exxon Valdez</i>
In the months following the Exxon Valdez oil spill (EVOS), 994 sea otters (Enhydra lutris) from oil-spill-affected areas died (Doroff et al. 1993). Carcasses collected from these areas and otters that died in rehabilitation centers are included in this number. The actual number that died was probably much greater.Within days...
Effects of urban flood-detention reservoirs on peak discharges in Gwinnett County, Georgia
G. W. Hess, E. J. Inman
1994, Water-Resources Investigations Report 94-4004
The effects of flood-detention reservoirs on peak discharges along downstream reaches in six urban drainage basins in Gwinnett County, Georgia, were studied during 1986-93 using the U.S. Geological Survey's Distributed Routing Rainfall-Runoff Model (DR3M). Short-term rainfall-runoff data were collected at selected stations in six urban drainage basins in Gwinnett County....
Hydrogeology, herbicides and nutrients in ground water and springs, and relation of water quality to land use and agricultural practices near Carlisle, Pennsylvania
D. J. Hippe, E. C. Witt III, R.M. Giovannitti
1994, Water-Resources Investigations Report 93-4172
Discharge and water-quality data collected in two adjacent karst-spring basins in Cumberland County, Pa., from May 1990 through April 1991 were used to (1) describe the hydrogeology of the area; (2) determine the concentrations of selected herbicides, herbicide-soil metabolites, and nutrients in water from wells and discharges from springs, (3)...
Water resources data, Arizona water year 1993
C.F. Smith, P.D. Rigas, L. K. Ham, N.R. Duet, D.W. Anning
1994, Water Data Report AZ-93-1
The Water Resources Division of the U.S. Geological Survey, in cooperation with State agencies, obtains a large amount of data pertaining to the water resources of Arizona each water year. These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of the water...
Yields of bedrock wells in Massachusetts
B. P. Hansen, A.C. Simcox
1994, Water-Resources Investigations Report 93-4115
Six to seven percent of the population of Massachusetts obtains its water from domestic bedrock wells. Additional public, commercial, industrial, and domestic supplies from bedrock will be needed in the future. Information about the factors that are related to large well yields is needed. The factors associated with well yields...
Stream velocities and reaeration coefficients for the South Umpqua River between Tiller and Roseburg, Oregon, 1991
Antonius Laenen, W. H. Woo
1994, Water-Resources Investigations Report 92-4191
Dye-tracer and gas-tracer studies were done in July and September 1991 during low flows on four reaches of the South Umpqua River between Tiller and Roseburg, Oregon. For a stream flow of 435 cubic feet per second at the Brockway streamflow monitoring site (14312000), the average stream velocity between Tiller...
Water resources on and near Indian lands in northeastern Kansas and southeastern Nebraska; hydrologic data through 1990
L.D. Brewer, T. J. Trombley, M.L. Pomes
1994, Open-File Report 94-35
Four Kansas Indian Tribes, the Iowa, Kickapoo, Potawatomi, and Sac & Fox are interested in developing the water resources on and near their respective tribe lands. This report presents climatic and geohydrologic data that are useful in describing the available water resources in the 4,005-square-mile area in northeastern Kansas and...
Pesticide-sampling equipment, sample-collection and processing procedures, and water-quality data at Chicod Creek, North Carolina, 1992
T.K. Manning, K.E. Smith, C.D. Wood, J. B. Williams
1994, Open-File Report 94-50
Water-quality samples were collected from Chicod Creek in the Coastal Plain Province of North Carolina during the summer of 1992 as part of the U.S. Geological Survey's National Water-Quality Assessment Program. Chicod Creek is in the Albemarle-Pamlico drainage area, one of four study units designated to test equipment and procedures...
Evapotranspiration estimation using a normalized difference vegetation index transformation of satellite data
P. M. Seevers, R. W. Ottmann
1994, Hydrological Sciences Journal (39) 333-345
Evapotranspiration of irrigated crops on two irrigation service areas along the lower Colorado River was estimated using a normalized difference vegetation index of satellite data. A procedure was developed which equated the index to crop coefficients. Evapotranspiration estimates for fields for three dates of thematic mapper data were highly correlated...

Specific yield as determined by type-curve analysis of aquifer-test data
Allen F. Moench
1994, Ground Water (32) 949-957
The commonly used analytical solution developed by Neuman for a homogeneous, water-table aquifer assumes that the drainage of pores in the zone above the water table due to lowering of the water table occurs instantaneously. Noninstantaneous drainage of pores in the unsaturated zone accounts for the finding that both type-curve...
