Altitude and configuration of the potentiometric surface in the crystalline and metasedimentary rocks in Sadsbury, West Caln, and West Sadsbury townships, Chester County, Pennsylvania, April 1993 through August 1994 Altitude and configuration of the potentiometric surface in the crystalline and metasedimentary rocks in Sadsbury, West Caln, and West Sadsbury townships, Chester County, Pennsylvania, April 1993 through August 1994
A map showing ground-water levels in crystalline and metasedimentary rocks in Sadsbury, West Caln, and West Sadsbury Townships, Chester County, Pennsylvania, was constructed from water levels measured in wells from April 1993 through August 1994. Pre-1993 measurements were incorporated on the map to provide control in areas where more recent data were not available. Because little ground...

Hydrophobic organochlorine compounds sequestered in submersed aquatic macrophytes (Hydrilla yerticillata (L.f.) Royle) from the tidal Potomac River (USA) Hydrophobic organochlorine compounds sequestered in submersed aquatic macrophytes (Hydrilla yerticillata (L.f.) Royle) from the tidal Potomac River (USA)
The potential for hydrophobic organochlorine contaminants to be sequestered in submersed aquatic vegetation was evaluated by determining the concentrations of cis- and trans-chlordane, dieldrin, and polychlorinated biphenyls (PCBs) in feral aquatic macrophytes (Hydrilla verticillata (L.f.) Royle) collected from the tidal Potomac River. Similarities in mean dry-weight concentrations of...

Cytochrome P450 and contaminant concentrations in nestling black-crowned night-herons and their interrelation with sibling embryos Cytochrome P450 and contaminant concentrations in nestling black-crowned night-herons and their interrelation with sibling embryos
Hepatic cytochrome P450-associated monooxygenase activities were measured in 11-d-old nestling black-crowned night-herons (Nycticorax nycticorax) collected from a reference site (next to Chincoteague National Wildlife Refuge, VA, USA) and three contaminated sites (Cat Island, Green Bay, WI, USA; Bair Island, San Francisco Bay, CA, USA; and West Marin Island, San Francisco Bay, CA, USA)

Strontium Strontium
Part of the Annual Commodities Review 1995. In 1995, U.S. strontium imports and consumption increased nearly 30 percent due to increased domestic production of color television picture tube glass. However, strontium compound exports fell during 1995. Strontium is also used in the production of permanent ceramic ferrite magnets. Strontium nitrate, strontium chromate, and strontium...

Construction aggregates Construction aggregates
Part of the Annual Commodities Review 1995. Production of construction aggregates such as crushed stone and construction sand and gravel showed a marginal increase in 1995. Most of the 1995 increases were due to funding for highway construction work. The major areas of concern to the industry included issues relating to wetlands classification and the classification of crystalline silica...

Flood magnitude and frequency of Little Mantual Creek at the culvert at milepost 7.8 on New Jersey Route 44, and at the Conrail culvert 0.20 miles downstream, West Deptford Township, Gloucester County, New Jersey Flood magnitude and frequency of Little Mantual Creek at the culvert at milepost 7.8 on New Jersey Route 44, and at the Conrail culvert 0.20 miles downstream, West Deptford Township, Gloucester County, New Jersey
The magnitude and frequency of floods at Little Mantua Creek at the culvert on New Jersey Route 44 at milepost 7.8 and at the Conrail culvert 0.20 miles downstream, in West Deptford Township, New Jersey, were determined by using the New Jersey Department of Environmental Protection Special Report 38 method. Flood-magnitude and -frequency estimates, as well as drainage-basin...

Flood magnitude and frequency of Jacks Run at the culvert on U.S. Route 206, Southampton Township, Burlington County, New Jersey Flood magnitude and frequency of Jacks Run at the culvert on U.S. Route 206, Southampton Township, Burlington County, New Jersey
Flood magnitude and frequency of Jacks Run at the culvert on U.S. Route 206, Southampton Township, New Jersey, were determined by using the rational method. Flood magnitude and frequency estimates, as well as basin characteristics, are included in this report. The 100-year-flood estimate is 29 cubic feet per second.
