Hydrogeology and analysis of ground-water-flow system, Sagamore Marsh area, southeastern Massachusetts
A study of the hydrogeology and an analysis of the ground-water-flow system near Sagamore Marsh, southeastern Massachusetts, was undertaken to improve the understanding of the current (1994 95) hydrogeologic conditions near the marsh and how the ground-water system might respond to proposed changes in the tidal-stage regime of streams that flood and drain the marsh. Sagamore Marsh is in a coastal

HYSEP: A Computer Program for Streamflow Hydrograph Separation and Analysis
HYSEP is a computer program that can be used to separate a streamflow hydrograph into base-flow and surface-runoff components. The base-flow component has traditionally been associated with ground-water discharge and the surface-runoff component with precipitation that enters the stream as overland runoff. HYSEP includes three methods of hydrograph separation that are referred to in the literature

Methodology used to produce an encoded 1:100,000-scale digital hydrographic data layer for the Pacific Northwest
The U.S. Geological Survey (USGS) has produced a River Reach File data layer for the Pacific Northwest for use in water-resource management applications. The Pacific Northwest (PNW) River Reach Files, a geo-referenced river reach data layer at 1:100,000-scale, are encoded with the U.S. Environmental Protection Agency"s (EPA) reach numbers. The encoding was a primary task of the River Reach project

Bacteriological quality of ground water used for household supply, Lower Susquehanna River basin, Pennsylvania and Maryland
This report describes the bacteriological results of a ground-water study conducted from 1993 to 1995 as part of the U.S. Geological Survey's National Water-Quality Assessment Program in the Lower Susquehanna River Basin study unit. Water samples collected from 146 household supply wells were analyzed for fecal-indicator organisms including total coliform, fecal coliform, Escherichia coli (E. coli

Occurrence of the gasoline oxygenate MTBE and BTEX compounds in urban stormwater in the United States, 1991-95
Methyl tert-butyl ether (MTBE) is a gasoline oxygenate. Oxygenates such as MTBE, when added to gasoline, increase the gasoline's oxygen level and decrease vehicular carbon monoxide emissions and ozone levels in the atmosphere. MTBE disperses rapidly in water, was the second most frequently detected volatile organic compound (VOC) in a study of shallow urban ground water, and is less biodegradable

Precipitation, streamflow and water quality data from selected sites in the City of Charlotte and Mecklenburg County, North Carolina, 1993-95
Charlotte and Mecklenburg County from October 1993 through June 1995 to identify the type, concentration, and amount of nonpoint-source stormwater runoff within the area. The data collected include measurements of precipitation; streamflow; physical characteristics, such as water temperature, pH, specific conductance, biochemical oxygen demand, oil and grease, and suspended sediment concentrations

Assessment of petroleum-hydrocarbon contamination in the surficial sediments and ground water at three former underground storage tank locations, Fort Jackson, South Carolina, 1995
Ground-water and sediment contamination by petroleum hydrocarbons resulting from leaks and overfills was detected during tank removal activities at three former underground storage tank locations at Fort Jackson, near Columbia, South Carolina. Investigations were initiated to assess the effect of contamination to the surficial aquifer at Sites 1062, 2438, and 2444. These investigations involved th

Ground-water resources data for Warren County, Pennsylvania
This report presents lithologic, hydrologic, and chemical data collected during a study of the ground-water resources of Warren County, Pa. The study was conducted during 1983-90 by the U.S. Geological Survey, in cooperation with the Pennsylvania Department of Conservation and Natural Resources, Bureau of Topographic and Geologic Survey, and the Warren County Commissioners. The data include inform

National Water-Quality Assessment of the Trinity River Basin, Texas - Well and Water-Quality Data from the Outcrop of the Woodbine Aquifer in Urban Tarrant County, 1993
An urban land-use study of the shallow water-bearing zones of the Woodbine aquifer outcrop area began in 1993 as a part of the National Water-Quality Assessment Program for the Trinity River Basin. Thirty-eight wells located within predominantly commercial or residential settings were selected for this study. Water samples were collected from each well and analyzed for 186 waterquality constituent

Estimated water withdrawals and use in Illinois, 1990
The total amount of water withdrawn in Illinois during 1990 was about 18,016 million gallons per day (Mgal/d). This amount was about 740 Mgal/d less than in 1988. The total water withdrawn for thermoelectric-power generation was about 15,170 Mgal/d; about 370 Mgal/d was consumptively used. About 936 Mgal/d, or 33 percent, of the total water withdrawn in Illinois during 1990 was ground water, exclu

Hydrogeology of the Southeastern Coastal Plain aquifer system in Mississippi, Alabama, Georgia, and South Carolina
The Southeastern Coastal Plain aquifer system consists of a thick sequence of unconsolidated to poorly consolidated Cretaceous and Tertiary rocks that extend from Mississippi to South Carolina. Four regional sand and gravel aquifers are separated by three regional confining units of clay, shale, and chalk that do not conform everywhere to stratigraphic boundaries. The change in geologic facies is
