Study design and preliminary data analysis for a streambank fencing project in the Mill Creek Basin, Pennsylvania Study design and preliminary data analysis for a streambank fencing project in the Mill Creek Basin, Pennsylvania
The Pequea Creek and Mill Creek Basins within Lancaster and Chester Counties in Pennsylvania have been identified as areas needing control of nonpoint-source (NFS) pollution to improve water quality. The two basins are a total of approximately 200 square miles and are primarily underlain by carbonate bedrock. Land use is predominantly agriculture. The most common agricultural NFS...

Bacteriological quality of ground water used for household supply, Lower Susquehanna River basin, Pennsylvania and Maryland Bacteriological quality of ground water used for household supply, Lower Susquehanna River basin, Pennsylvania and Maryland
This report describes the bacteriological results of a ground-water study conducted from 1993 to 1995 as part of the U.S. Geological Survey's National Water-Quality Assessment Program in the Lower Susquehanna River Basin study unit. Water samples collected from 146 household supply wells were analyzed for fecal-indicator organisms including total coliform, fecal coliform, Escherichia...

Flood magnitude and frequency of Main Ditch at the culvert on New Jersey Route 44 and at the Conrail culvert downstream, West Deptford Township, Gloucester County, New Jersey Flood magnitude and frequency of Main Ditch at the culvert on New Jersey Route 44 and at the Conrail culvert downstream, West Deptford Township, Gloucester County, New Jersey
The magnitude and frequency of floods at Main Ditch at the culvert on New Jersey Route 44 at milepost 8.3 and at the Conrail culvert 0.21 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 characteristics, are...

Flood magnitude and frequency of Monongahela Brook at the culvert on New Jersey Route 41, Deptford Township, Gloucester County, New Jersey Flood magnitude and frequency of Monongahela Brook at the culvert on New Jersey Route 41, Deptford Township, Gloucester County, New Jersey
Flood magnitude and frequency of Monongahela Brook in Deptford Township, Gloucester County, New Jersey, were determined by using the rational method. Flood-magnitude and -frequency estimates, as well as drainage-basin characteristics, are included in this report. The 100-year-flood estimate is 80 cubic feet per second.

Mercury poisoning in wildlife Mercury poisoning in wildlife
Mercury is an intriguing contaminant because it has complex chemical properties, a wide range of harmful effects, and an infinite persistence in the environment. Die-offs of wildlife due to mercury have occurred in many countries, especially before mercury seed dressings were banned. Today, most mercury problems are associated with aquatic environments. Methylmercury, the most toxic...

Hydrogeologic framework of the diabase aquifer at the Boarhead Farms Superfund site, Bridgeton Township, Bucks County, Pennsylvania Hydrogeologic framework of the diabase aquifer at the Boarhead Farms Superfund site, Bridgeton Township, Bucks County, Pennsylvania
The hydrogeologic investigation at the Boarhead Farms Superfund site was done to characterize the framework of the diabase aquifer underlying the site. The primary water-producing fracture system is less than 30 feet below land surface. Water-bearing fractures were not found deeper than 50 feet below land surface. The overburden soil is thin and ranges from 4 to 14 feet thick. The...

Ecology, Conservation, and Management of Colonial Waterbirds in the Mediterranean Region Ecology, Conservation, and Management of Colonial Waterbirds in the Mediterranean Region
(excerpt from Forword) The Mediterranean Symposium, part of the annual conference of The Colonial Waterbird Society in October 1993 in Arles, France, was the successful culmination of ideas shared among leading European waterbird and wetland scientists... Both invited and contributed papers focused on two areas - breeding biology (especially of threatened or little known species), and...
Environmental Contaminants in Wildlife: Interpreting Tissue Concentrations Environmental Contaminants in Wildlife: Interpreting Tissue Concentrations
Covers the complex issue of how to evaluate contaminants in wildlife. This comprehensive resource deals with the question: 'How much of a chemical in the tissues of an animal is harmful?' Features: Authoritative and sound advice is provided on many environmental contaminants, including what the contaminants are and how to interpret the data on them. Each chapter includes a review of the
