Modification of a method-of-characteristics solute-transport model to incorporate decay and equilibrium-controlled sorption or ion exchange Modification of a method-of-characteristics solute-transport model to incorporate decay and equilibrium-controlled sorption or ion exchange

The U.S. Geological Survey computer model of two-dimensional solute transport and dispersion in ground water (Konikow and Bredehoeft, 1978) has been modified to incorporate the following types of chemical reactions: (1) first-order irreversible rate-reaction, such as radioactive decay; (2) reversible equilibrium-controlled sorption with linear, Freundlich, or Langmuir isotherms; and (3)...

Altitude and configuration of the potentiometric surface in the Triassic sandstones and shales, northeastern Chester County, Pennsylvania, September 1987 through January 1988 Altitude and configuration of the potentiometric surface in the Triassic sandstones and shales, northeastern Chester County, Pennsylvania, September 1987 through January 1988

The altitude of the water levels in the Triassic sandstones and shales in northeastern Chester County is shown on a map at a scale of 1:24,000. The map is based on water levels in 173 non-pumping drilled and dug wells measured in 1956 and 1965, and on the altitude of two springs that were flowing in November and December 1987. Water level altitudes are contoured at an interval of 20 ft...

Surface-water quality in the West Branch Susquehanna River basin, Pennsylvania: An appraisal of areal and temporal variability from 1962 to 1982 in hydrologic accounting unit 020502 Surface-water quality in the West Branch Susquehanna River basin, Pennsylvania: An appraisal of areal and temporal variability from 1962 to 1982 in hydrologic accounting unit 020502

The West Branch Susquehanna River basin has a drainage area of 6,955 square miles in north-central Pennsylvania and comprises Hydrologic Accounting Unit 020502. A National Stream Quality Accounting Network (NASQAN) waterquality data collection site, maintained by the U.S. Geological Survey, is located on the river near its mouth at Lewisburg, Pennsylvania. Water-quality data are...

Water quality of the West Branch Lackawaxen River and limnology of Prompton Lake, Wayne County, Pennsylvania, October 1986 through September 1987 Water quality of the West Branch Lackawaxen River and limnology of Prompton Lake, Wayne County, Pennsylvania, October 1986 through September 1987

The water quality of the West Branch Lackawaxen River and the limnology of Prompton Lake in northeastern Pennsylvania were studied from October 1986 through September 1987 to determine past and present water-quality conditions in the basin, and to determine the possible effects of raising the lake level on the water quality of the Lake, of the river downstream, and of ground water. Past...

Relation of ground-water quality to land use in the Philadelphia, Pennsylvania-Camden, New Jersey area Relation of ground-water quality to land use in the Philadelphia, Pennsylvania-Camden, New Jersey area

The distributions of common dissolved constituents, trace metals, and volatile organic compounds in ground water near Philadelphia, Pennsylvania, and Camden, New Jersey, are influenced by local geology and land use. Many common dissolved constituents are more concentrated in ground water beneath urban and industrial areas than in water beneath suburban and undeveloped and agricultural...

Withdrawals and consumptive use of water in Pennsylvania, 1984 Withdrawals and consumptive use of water in Pennsylvania, 1984

Total accountable water withdrawals in Pennsylvania during 1984 were 14,033.66 Mga/d (million gallons per day); of that total, 5.2 percent (729.53 Mgal/d) was supplied from ground-water sources in 94.8 percent (13,302.12 Mgal/d) was supplied from surface-water sources. Thermoelectric power generation accounted for 71 percent of the total withdrawals (10,010.60 Mgal/d); this was followed...

Hydrologic data for Indian Creek basin, Fayette and Westmoreland counties, Pennsylvania, 1985-87 Hydrologic data for Indian Creek basin, Fayette and Westmoreland counties, Pennsylvania, 1985-87

Hydrologic data were collected in the Indian Creek basin, Fayette and Westmoreland Counties, Pennsylvania. Since the early 1900's, coal in the basin has been extensively mined by both underground and surface-mining techniques. Data-collection sites were located in mined and unmined areas of the basin. The hydrologic data presented are from 5 continuous-record surfacewater data-collection...

Geohydrology and water quality in the vicinity of the Gettysburg National Military Park and Eisenhower National Historic Site, Pennsylvania Geohydrology and water quality in the vicinity of the Gettysburg National Military Park and Eisenhower National Historic Site, Pennsylvania

Wells in the Gettysburg National Military Park, Eisenhower National Historic Site, and Gettysburg Borough supply drinking water to the park staff and, annually, more than 1 million visitors. These water resources are vulnerable to contamination by pollutants from activities in and outside park boundaries. This report describes the hydrogeology and ground-water quality of a 12-square-...

Streamflow and water-quality data for Meadow Run basin, Fayette County, Pennsylvania, December 1987 - November 1988 Streamflow and water-quality data for Meadow Run basin, Fayette County, Pennsylvania, December 1987 - November 1988

Streamflow and water-quality data were collected throughout the Meadow Run basin, Fayette County, Pennsylvania, from December 7, 1987 through November 15, 1988, to determine the prevailing quality of surface water over a range of hydrologic conditions. This data will assist the Pennsylvania Department of Environmental Resources during its review of coal-mine permit applications. A water...
