Historical ground-water-flow patterns and trends in iron concentrations in the Potomac-Raritan-Magothy aquifer system in parts of Philadelphia, Pennsylvania, and Camden and Gloucester Counties, New Jersey Historical ground-water-flow patterns and trends in iron concentrations in the Potomac-Raritan-Magothy aquifer system in parts of Philadelphia, Pennsylvania, and Camden and Gloucester Counties, New Jersey

The Potomac-Raritan-Magothy (PRM) aquifer system is an important sole-source ground-water supply in Camden and Gloucester Counties, N.J. Elevated iron concentrations are a persistent water-quality problem associated with ground water from the PRM. In Philadelphia, the PRM no longer is usable as a water supply because of highly elevated concentrations of iron (as high as 429 mg/L...

MTBE concentrations in ground water in Pennsylvania MTBE concentrations in ground water in Pennsylvania

The distribution, concentrations, and detection frequency of methyl tert-butyl-ether (MTBE), a gasoline additive used in reformulated gasoline to improve air quality, were characterized in Pennsylvania's ground water. Two sources of MTBE in ground water, the atmosphere and storage-tank release sites, were examined. An analysis of atmospheric MTBE concentrations shows that MTBE detections...

Design and performance of limestone drains to increase pH and remove metals from acidic mine drainage, Chapter 2 Design and performance of limestone drains to increase pH and remove metals from acidic mine drainage, Chapter 2

Data on the construction characteristics and the composition of influent and effluent at 13 underground, limestone-filled drains in Pennsylvania and Maryland are reported to evaluate the design and performance of limestone drains for the attenuation of acidity and dissolved metals in acidic mine drainage. On the basis of the initial mass of limestone, dimensions of the drains, and...

Geohydrology of Southeastern Pennsylvania Geohydrology of Southeastern Pennsylvania

Rapid population growth in southeastern Pennsylvania has increased the demand for ground water. In an effort to address the increased ground-water needs, a ground-water investigation in a 5,200-square-mile area of southeastern Pennsylvania was initiated. Information on the geohydrologic system of the area and the water-bearing capabilities of 51 geohydrologic units in six physiographic...

Ground-Water Resources of Big Elk Creek Basin, Pennsylvania and Maryland Ground-Water Resources of Big Elk Creek Basin, Pennsylvania and Maryland

Many rural areas in southeastern Pennsylvania, including the Big Elk Creek Basin, are undergoing a rapid population increase. New development and an expanding population increase consumptive water use, increase surface runoff, and have the potential to reduce ground-water recharge. The Big Elk Creek Basin is between the Delaware and Susquehanna River Basins and drains directly to the...

Software user's guide for determining the Pennsylvania scour critical indicator code and streambed scour assessment rating for roadway bridges Software user's guide for determining the Pennsylvania scour critical indicator code and streambed scour assessment rating for roadway bridges

This report presents the instructions required to use the Scour Critical Bridge Indicator (SCBI) Code and Scour Assessment Rating (SAR) calculator developed by the Pennsylvania Department of Transportation (PennDOT) and the U.S. Geological Survey to identify Pennsylvania bridges with excessive scour conditions or a high potential for scour. Use of the calculator will enable PennDOT...

Prediction of velocities for a range of streamflow conditions in Pennsylvania Prediction of velocities for a range of streamflow conditions in Pennsylvania

A regression equation that is used nationwide to predict traveltime in streams during periods of low and moderate flow was developed by H.E. Jobson in 1996. Because none of the data used in the development of the equation were from streams in Pennsylvania, velocities for low and moderate flows predicted by the equation were compared to velocities measured during time-of-travel studies on...

The U.S. Geological Survey and the Chesapeake Bay – The role of science in environmental restoration The U.S. Geological Survey and the Chesapeake Bay – The role of science in environmental restoration

The Chesapeake Bay is the Nation's largest estuary and historically supported one of the most productive fisheries in the world. In addition to supporting aquatic communities and wildlife, the bay's watershed serves the economic and recreational needs of 15 million people. The fertile soils of the watershed support significant agricultural production. Unfortunately, the commercial...

Geohydrology and ground-water quality, Big Elk Creek Basin, Chester County, Pennsylvania, and Cecil County, Maryland Geohydrology and ground-water quality, Big Elk Creek Basin, Chester County, Pennsylvania, and Cecil County, Maryland

A study of ground-water quantity and quality was conducted in the Big Elk Creek Basin, a rural area undergoing rapid growth. The 79.4-square mile study area is in the Piedmont Physiographic Province and is underlain almost entirely by crystalline rocks. Most of the basin in Pennsylvania is underlain by Wissahickon Schist, a fractured crystalline- rock aquifer. Yields of wells in the...
