National water summary 1986: Hydrologic events and ground-water quality

Ground water is one of the most important natural resources of the United States and degradation of its quality could have a major effect on the welfare of the Nation. Currently (1985), ground water is the source of drinking water for 53 percent of the Nation's population and for more than 97 percent of its rural population. It is the source of about 40 percent of the Nation's public water supply,

Ground-water contamination near a uranium tailings disposal site in Colorado

Contaminants from uranium tailings disposed of at an active mill in Colorado have seeped into the shallow ground water onsite. This ground water discharges into the Arkansas River Valley through a superposed stream channel cut in the resistant sandstone ridge at the edge of a synclinal basin. In the river valley, seasonal surface-water irrigation has a significant impact on hydrodynamics. Water le

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 streamflow and

Effect of urbanization on the water resources of eastern Chester County, Pennsylvania

The effects of human activity on the water resources of a 207-square-mile area of eastern Chester County was evaluated. The most serious consequence of urbanization is the contamination of ground water by volatile organic compounds, which were detected in 39 percent of the 70 wells sampled. As many as nine compounds were found in one water sample, and the concentration of total volatile organic co

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 mines are

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 significant at the 9

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 much of th

Ground-water levels in the lower Paleozoic and Precambrian crystalline rocks, southeastern Chester County, Pennsylvania, July and August 1986

A water table contour map of the lower Paleozoic and Precambrian crystalline rocks of southeastern Chester County, Pennsylvania was constructed on the basis of water levels measured in 261 wells in July and August 1986, elevations of 11 springs that were flowing in July and August 1986, and water levels measured in 15 wells. Pre-1986 measurements were incorporated on the map to provide control in

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 water res
