Occurrence, distribution, and trends of volatile organic compounds in the Ohio River and its major tributaries, 1987-96
The Ohio River is a source of drinking water for more than 3 million people. Thus, it is important to monitor the water quality of this river to determine if contaminants are present, their concentrations, and if water quality is changing with time. This report presents an analysis of the occurrence, distribution, and trends of 21 volatile organic compounds (VOCs) along the main stem of the Ohio R

Stream water-quality characteristics and trends, James River basin, North Dakota, 1949-95
Water-quality data collected at 16 water-quality-sampling sites in the James River Basin during 1949-95 were statistically summarized. Analysis of variance of data ranks was used to make comparisons among sites for selected constituents that had 20 or more analyses per site. Statistically significant differences among sites were indicated for specific conductance, dissolved solids, major ions, and

Relation of Land Use to Streamflow and Water Quality at Selected Sites in the City of Charlotte and Mecklenburg County, North Carolina, 1993-98
Streamflow and water-quality data were collected at nine sites in the city of Charlotte and Mecklenburg County, North Carolina, during 1993–97. Six of the basins drained areas having relatively homogeneous land use and were less than 0.3 square mile in size; the other three basins had mixed land use. Atmospheric wet-deposition data were collected in three of the basins during 1997–98.Streamflow yi

WTAQ: A Computer Program for Calculating Drawdowns and Estimating Hydraulic Properties for Confined and Water-Table Aquifers
The computer program WTAQ calculates hydraulic-head drawdowns in a confined or water-table aquifer that result from pumping at a well of finite or infinitesimal diameter. The program is based on an analytical model of axial-symmetric ground-water flow in a homogeneous and anisotropic aquifer. The program allows for well-bore storage and well-bore skin at the pumped well and for delayed drawdown re

Water quality, physical habitat, and fish-community composition in streams in the Twin Cities metropolitan area, Minnesota, 1997-98
Water quality, physical habitat, and fish-community composition were characterized at 13 Twin Cities metropolitan area streams during low-flow conditions, September 1997. Fish communities were resampled during September 1998. Sites were selected based on a range of human population density. Nutrient concentrations were generally low, rarely exceeding concentrations found in agricultural streams or

Areal-reduction factors for the precipitation of the 1-day design storm in Texas
The reduction of the precipitation depth from a design storm for a point to an effective (mean) depth over a watershed often is important for cost-effective design of hydraulic structures by reducing the volume of precipitation. A design storm for a point is the depth of precipitation that has a specified duration and frequency (recurrence interval). The effective depth can be calculated by multip

Distribution and transport of polychlorinated biphenyls and associated particulates in the Milwaukee River System, Wisconsin, 1993-95
The distribution and transport of polychlorinated biphenyl (PCB) congeners were determined at various sites on Cedar Creek and its receiving stream, the Milwaukee River. PCB congener distributions were determined in the operationally defined dissolved phase, suspended-particle phase, and surficial bed sediments (0?2 centimeters depth). At most sites, the relative abundances of PCB congeners in the

Characterization and simulation of the quantity and quality of water in the Highland Lakes, Texas, 1983-92
The Highland Lakes, located in central Texas, are a series of seven reservoirs on the Colorado River (Lake Buchanan, Inks Lake, Lake Lyndon B. Johnson, Lake Marble Falls, Lake Travis, Lake Austin, and Town Lake). The reservoirs provide hydroelectric power for the area. In addition, Lake Austin and Town Lake also provide the public water supply for the Austin metropolitan area. Saline water release

Record Extension and Streamflow Statistics for the Pleasant River, Maine
Historical streamflow data for the Pleasant River are limited to 11 years (from 1980 to 1991) at the U.S. Geological Survey streamgaging station near Epping. Analysis of these data in conjunction with flow data from other nearby stations indicates that the 11 years of record for the Pleasant River may not be representative of longer-term conditions in the basin. A correlation between the historica

Ground-water system, estimation of aquifer hydraulic properties, and effects of pumping on ground-water flow in Triassic sedimentary rocks in and near Lansdale, Pennsylvania
Ground water in Triassic-age sedimentary fractured-rock aquifers in the area of Lansdale, Pa., is used as drinking water and for industrial supply. In 1979, ground water in the Lansdale area was found to be contaminated with trichloroethylene, tetrachloroethylene, and other man-made organic compounds, and in 1989, the area was placed on the U.S. Environmental Protection Agency's (USEPA) National P
