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

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

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

Hydrogeology and ground-water quality of Valley Forge National Historical Park, Montgomery County, Pennsylvania

Valley Forge National Historical Park is just southwest of the Commodore Semiconductor Group (CSG) National Priorities List (Superfund) Site, a source of volatile organic compounds (VOC's) in ground water. The 7.5-square-mile study area includes the part of the park in Lower Providence and West Norriton Townships in Montgomery County, Pa., and surrounding vicinity. The park is underlain by sedimen

Ground-water quality and its relation to hydrogeology, land use, and surface-water quality in the Red Clay Creek basin, Piedmont Physiographic Province, Pennsylvania and Delaware

The Red Clay Creek Basin in the Piedmont Physiographic Province of Pennsylvania and Delaware is a 54-square-mile area underlain by a structurally complex assemblage of fractured metamorphosed sedimentary and igneous rocks that form a water-table aquifer. Ground-water-flow systems generally are local, and ground water discharges to streams. Both ground water and surface water in the basin are used

Radon in ground water of the lower Susquehanna and Potomac River basins

Ground-water samples collected from 267 wells were analyzed for radon as part of a water-quality reconnaissance of subunits of the Lower Susquehanna and Potomac River Basins conducted by the United States Geological Survey (USGS) as part of the National Water-Quality Assessment (NAWQA) program. Radon is a product of the radioactive decay of uranium. Airborne radon has been cited by the Surgeon Gen

Hydrogeologic setting and simulation of pesticide fate and transport in the unsaturated zone of a regolith-mantled, carbonate-rock terrain near Newville, Pennsylvania

Physical and chemical data were collected from May 1991 through April 1993 at a 4.5 hectare field site in Cumberland County, Pa., about 5 kilometers southeast of Newville. These data were used to define the hydrogeologic setting of a field site representative of the intensively farmed carbonate valleys of southeastern and south-central Pennsylvania. The environmental processing of commonly used pe

Altitude and configuration of the potentiometric surface, December 6, 1994, in the carbonate rocks in part of East Whiteland and Charlestown townships, Chester County, Pennsylvania

A map showing ground-water levels in the carbonate rocks in part of East Whiteland and Charlestown Townships, Chester County, Pennsylvania, was constructed from water levels measured in 64 wells on December 6, 1994. Observed water-level altitudes range from 226 feet above sea level near Morehall Road to 400 feet above sea level near State Route 401 in East Whiteland Township.

A map showing ground-water levels in crystalline and metasedimentary rocks in Valley and West Brandywine Townships, Chester County, Pennsylvania, was constructed from water levels measured in wells from May 1992 through August 1993. Pre-1992 measurements were incorporated on the map to provide control in areas where more recent data were not available. Because little ground-water development has o
