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...

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...

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...

Water-resources activities of the U.S. Geological Survey in Pennsylvania, 1986-87 Water-resources activities of the U.S. Geological Survey in Pennsylvania, 1986-87

The U.S. Geological Survey 's water-resources activities in Pennsylvania are described. Some activities are topics of general interest to the water resources community while others are related to current water issues. The report also describes the mission of the Water Resources Division of the U. S. Geological Survey, and program funding, water issues, a listing of selected literature on...

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...

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...

Temperature of ground water at Philadelphia, Pennsylvania, 1979- 1981 Temperature of ground water at Philadelphia, Pennsylvania, 1979- 1981

Anthropogenic heat production has undoubtedly caused increased ground-water temperatures in many parts of Philadelphia, Pennsylvania, as shown by temperatures of 98 samples and logs of 40 wells measured during 1979-81. Most sample temperatures were higher than 12.6 degrees Celsius (the local mean annual air temperature), and many logs depict cooling trends with depth (anomalous gradients...

Estimating iron and aluminum content of acid mine discharge from a north-central Pennsylvania coal field by use of acidity titration curves Estimating iron and aluminum content of acid mine discharge from a north-central Pennsylvania coal field by use of acidity titration curves

Determination of acidity provides a value that denotes the quantitative capacity of the sample water to neutralize a strong base to a particular pH. However, much additional information can be obtained from this determination if a titration curve is constructed from recorded data of titrant increments and their corresponding pH values. The curve can be used to identify buffer...

Effects of surface coal mining on suspended-sediment discharge in a small mountain watershed, Fayette County, Pennsylvania Effects of surface coal mining on suspended-sediment discharge in a small mountain watershed, Fayette County, Pennsylvania

Data collected in the upper Stony Fork basin from July 1980 to November 1981 indicate that logging operations associated with block-cut surface mining temporarily increased suspended-sediment discharge of Stony Fork. However, the strip-mining operation did not increase the suspended sediment discharges of Stony Fork because of effective sediment-control measures. These controls included...
