Water quality in the lower Susquehanna River basin, Pennsylvania and Maryland, 1992-95

This report is intended to summarize major findings that emerged between 1992 and 1995 from the water-quality assessment of the lower Susquehanna River basin study unit and to relate these findings to water-quality issues of regional and national concern. The information is primarily intended for those who are involved in water-resource management. Yet, the information contained here may also inte

Effect of sewage sludge on formation of acidic ground water at a reclaimed coal mine

Data on rock, ground water, vadose water, and vadose gas chemistry were collected for two years after sewage sludge was applied at a reclaimed surface coal mine in Pennsylvania to determine if surface-applied sludge is an effective barrier to oxygen influx, contributes metals and nutrients to ground water, and promotes the acidification of ground water. Acidity, sulfate, and metals concentrations

Relationships between land uses and rainwater quality in a southcentral Pennsylvania watershed

ABSTRACT: Spatial and temporal variability in rainfall concentrations of nutrients, major ions, and herbicides was monitored at 7 locations in or near the Conodoguinet Creek watershed in south-central Pennsylvania from 1991.1993. Results were used to (1) compare precipitation quality in forested, agricultural and urban areas, and (2) assess the practicality of using volunteer citizen monitoring in

Southeastern Pennsylvania ground water protected area

Geographical Information System data sets were developed by the U.S. Geological Survey in cooperation with the Delaware River Basin Commission (DRBC). These data are related to groundwater resources for the DRBC's Southeastern Pennsylvania Groundwater Protected Area.

Characterizing a ground water basin in a New England mountain and valley terrain

A ground water basin is defined as the volume of subsurface through which ground water flows from the water table to a specified discharge location. Delineating the topographically defined surface water basin and extending it vertically downward does not always define the ground water basin. Instead, a ground water basin is more appropriately delineated by tracking ground water flowpaths with a ca

Surface-water quality changes after 5 years of nutrient management in the Little Conestoga Creek headwaters, Pennsylvania, 1989-91

A 5.82-square-mile drainage basin in the headwaters of the Little Conestoga Creek in Lancaster County, Pa., was investigated from October 1989 through September 1991 as part of a longer-term effort to determine the effects of nutrient management on surface-water quality. A previous investigation found no statistical evidence that implementation of nutrient management from 1986 to 1989 affected wat

Scour at bridges, what's it all about? Stream stability and scour-assessment at bridges in Pennsylvania

Scour is the removal of sediment (soil and rocks) from streambeds and streambanks caused by movingwater. Although scour may occur at any time, it is usually more significant during high flows, when the water is swift and deep. Swiftly movingwater has more energy (turbulence and velocity) to lift and transport sediment than slowly moving water.

Hydrogeologic investigation of the Malvern TCE Superfund Site, Chester County, Pennsylvania

The Malvern TCE Superfund Site, a former solvent recycling facility that now stores and sells solvents, consists of a plant and disposal area, which are approximately 1,900 ft (feet) apart. The site is underlain by an unconfined carbonate bedrock aquifer in which permeability has been enhanced in places by solution. Water levels respond quickly to precipitation and show a similar seasonal variatio

Evaluation of selected wells in Pennsylvania's observation-well program as of 1993

In 1993, the U.S. Geological Survey operated 62 observation wells in 60 of Pennsylvania's 67 counties in cooperation with the Pennsylvania Department of Environmental Resources. These wells attempt to monitor an aerial extent of 45,000 square miles and penetrate 39 geologic formations or water-bearing units of 14 physiographic provinces. Some wells were drilled specifically for the observation-wel
