Water-use analysis program for the Neshaminy Creek basin, Bucks and Montgomery counties, Pennsylvania Water-use analysis program for the Neshaminy Creek basin, Bucks and Montgomery counties, Pennsylvania

A water-use analysis computer program was developed for the Neshaminy Creek Basin to assist in managing and allocating water resources in the basin. The program was developed for IBM-compatible personal computers. Basin analysis and the methodologies developed for the Neshaminy Creek Basin can be transferred to other watersheds. The development and structure of the water-use analysis...

National water summary on wetland resources National water summary on wetland resources

This National Water Summary on Wetland Resources documents wetland resources in the United States. It presents an overview of the status of knowledge of wetlands at the present time-what they are, where they are found, why they are important, and the controversies surrounding them, with an emphasis on their hydrology. Wetland resources in each State, the District of Columbia (combined...

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...

Direct simulation of groundwater age Direct simulation of groundwater age

A new method is proposed to simulate groundwater age directly, by use of an advection-dispersion transport equation with a distributed zero-order source of unit (1) strength, corresponding to the rate of aging. The dependent variable in the governing equation is the mean age, a mass-weighted average age. The governing equation is derived from residence-time-distribution concepts for the...

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...

Water quality of large discharges from mines in the anthracite region of eastern Pennsylvania Water quality of large discharges from mines in the anthracite region of eastern Pennsylvania

In 1991, 99 of the 102 coal mines in the anthracite coal fields of Pennsylvania that discharged 1.0 cubic foot per second or more when water-quality samples were collected in 1975 were revisited. Water was not discharging from 15 of these 99 mines in 1991. Discharge, water temperature, specific conductance, pH, dissolved oxygen, sulfate, iron, manganese, alkalinity, and acidity were...

Geohydrology of the Stockton Formation and cross-contamination through open boreholes, Hatboro Borough and Warminster Township, Pennsylvania Geohydrology of the Stockton Formation and cross-contamination through open boreholes, Hatboro Borough and Warminster Township, Pennsylvania

The study area consists of a 9-square-mile area underlain by sedimentary rocks of the middle arkose member of the Stockton Formation of Upper Triassic age. In the Hatboro area, the Stockton Formation strikes approximately N. 65 degrees E. and dps approximately 9 degrees NW. The rocks are chiefly arkosic sandstone and siltstone. Rocks of the Stocton Formation form a complex, heterogeneous

Factors affecting phosphorus transport at a conventionally-farmed site in Lancaster County, Pennsylvania, 1992-95 Factors affecting phosphorus transport at a conventionally-farmed site in Lancaster County, Pennsylvania, 1992-95

The U.S. Geological Survey and the Bureau of Land and Water Conservation of the Pennsylvania Department of Environmental Protection conducted a cooperative study to determine the effects of manure application and antecedent soil-phosphorus concentrations on the transport of phosphorus from the soil of a typical farm site in Lancaster County, Pa., from September 1992 to March 1995. The...
