Physical, chemical, and biological data for selected streams in Chester County, Pennsylvania, 1969-80

This report presents physical, chemical, and biological data collected at 50 sampling sites on selected streams in Chester County, Pennsylvania from 1969 to 1980. The physical data consist of air and water temperature, stream discharge, suspended sediment, pH, specific conductance, and dissolved oxygen. The chemical data consist of laboratory determinations of total nutrients, major ions, and trac

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. The surfac

Groundwater velocity magnitude in radionuclide transport calculations

Analytical solutions have been developed for many conceptual models of solute transport in groundwater (Bear 1979). Although these models usually rely on assumptions too restrictive for accurate description of actual field situations, they are useful in understanding groundwater transport and in evaluating the relative importance of the subsurface processes affecting transport. In addition, these

Evaluation of agricultural best-management practices in the Conestoga River headwaters, Pennsylvania; methods of data collection and analysis and description of study areas

The U.S. Geological Survey is conducting a water quality study as part of the nationally implemented Rural Clean Water Program in the headwaters of the Conestoga River, Pennsylvania. The study, which began in 1982, was designed to determine the effect of agricultural best management practices on surface--and groundwater quality. The study was concentrated in four areas within the intensively farme

Evaluation of the ground-water resources of the lower Susquehanna River basin, Pennsylvania and Maryland

Ground water in the 3,458-square-mile lower Susquehanna River basin occupies secondary openings in bedrock. The distribution of openings is a function of lithology, depth, and topography. Local flow systems account for most of the total ground-water flow. Average annual recharge for the lower basin is 1,857 million gallons per day, most of which discharges to streams. The water table is a subdued

Simulation of ground-water flow in aquifers along the Susquehanna River in Columbia County, Pennsylvania

A numerical model of groundwater flow was developed for a 10.3 sq mi area along the Susquehanna River in Columbia County, east central Pennsylvania. Groundwater in the model area primarily is in secondary openings in the carbonate--and clastic-rock aquifers and primary openings in the glacial-outwash aquifer that discontinuously overlies bedrock. The groundwater flow model was calibrated under ave
