Determination of benthic-invertebrate indices and water-quality trends of selected streams in Chester County, Pennsylvania, 1969-80 Determination of benthic-invertebrate indices and water-quality trends of selected streams in Chester County, Pennsylvania, 1969-80

The trends of biological and chemical data collected for 12 years (1969-80) from 46 sites in Chester County were evaluated by using the sea- sonal Kendall test. Brillouin's diversity index was calculated and plotted against time for each site. The diversity index at 7 sites had upward trends significant at the 99-percent confidence level, the index at 9 sites had upward trends...

Surface-water quality in Pequea Creek basin, Pennsylvania, 1977-79 Surface-water quality in Pequea Creek basin, Pennsylvania, 1977-79

A study of the Pequea Creek basin was conducted by the U.S. Geological Survey, in cooperation with the Susquehanna River Basin Commission and the EPA from February 1977 through March 1979. Pequea Creek drains an intensive agricultural area of 154 sq mi in southeastern Pennsylvania, and enters the Susquehanna River 30 mi north of the Chesapeake Bay. The study included measurement of...

Hydrogeology and ground-water quality at a land reclamation site, Neshaminy State Park, Pennsylvania Hydrogeology and ground-water quality at a land reclamation site, Neshaminy State Park, Pennsylvania

At Neshaminy State park, the most important aquifer is the informally named 'Trenton gravel' of Pleistocene age, which consists of poorly sorted sand and gravel. This is underlain by less permeable crystalline rock that limits the downward movement of water. Up to 5 feet of Holocene (or perhaps Pleistocene) alluvium consisting of clay and silt was deposited above the Trenton gravel, but...

Quality of water in mines in the Western Middle Coal Field, Anthracite Region, east-central Pennsylvania Quality of water in mines in the Western Middle Coal Field, Anthracite Region, east-central Pennsylvania

The quality of mine water in the 75 sq-mi Western Middle anthracite field, Pennsylvania was determined by sampling discharges and boreholes at 60 abandoned and flooded mines during 1975-78. The Vulcan-Buck Mountain mine, east-northeast of Mahanoy City, contains an estimated 6,100 acre-ft of water with a specific conductance of 380 to 460 micromhos and a pH of 4.4 to 4.6 units. Twenty-two...

Flood of November 1985 in West Virginia, Pennsylvania, Maryland, and Virginia Flood of November 1985 in West Virginia, Pennsylvania, Maryland, and Virginia

Rainfall in excess of 10 inches occurred during the first 5 days of November 1985, resulting in devastating flooding in the Mid-Atlantic states of West Virginia, Pennsylvania, Maryland, and Virginia. Throughout the area, many streams exceeded previously known flood heights and discharges and, in many cases, the recurrence interval of peak discharges exceeded 100 years. The peak stage and

Techniques for estimating streamflow characteristics in the Eastern and Interior coal provinces of the United States Techniques for estimating streamflow characteristics in the Eastern and Interior coal provinces of the United States

Techniques are presented for estimating various streamflow characteristics, such as peak flows, mean monthly and annual flows, flow durations, and flow volumes, at ungaged sites on unregulated streams in the Eastern Coal region. Streamflow data and basin characteristics for 629 gaging stations were used to develop multiple-linear-regression equations. Separate equations were developed...

Areal and temporal variability of selected water-quality characteristics in two hydrologic-benchmark basins in the northeastern United States Areal and temporal variability of selected water-quality characteristics in two hydrologic-benchmark basins in the northeastern United States

Two U.S. Geological Survey National Hydrologic Benchmark stations--Young Womans Creek near Renovo, Pennsylvania and Esopus Creek at Shandaken, New York--were studied to (1) define, both areally and temporally, variations of stream acidity and other water quality characteristics within the basins; (2) evaluate how well the data collected at the Benchmark station represent the water...

Temporal changes in sulfate, chloride, and sodium concentrations in four eastern Pennsylvania streams Temporal changes in sulfate, chloride, and sodium concentrations in four eastern Pennsylvania streams

Trend analyses of 20 years or more of chemical quality and streamflow data for four streams in eastern Pennsylvania indicate that sulfate has decreased significantly in three of the four basins studied, while sodium and chloride have generally increased. The majority of chemical quality changes occurred in the late 1950 's and early 1960 's coincident with significant cultural changes...

Nitrate-nitrogen and herbicide ground-water data is being collected by the u.s. Geological Survey as part of the nationwide Rural Clean Water Program designed to determine the effects of agricultural-management practices on water quality. Data collected from September 1982 to October 1983 · in the 188-square mile intensively farmed upper Conestoga River basin indicates high nitrate and...
