Water-quality assessment of the Lower Susquehanna River Basin, Pennsylvania and Maryland: Design and implementation of water-quality studies, 1992-95 Water-quality assessment of the Lower Susquehanna River Basin, Pennsylvania and Maryland: Design and implementation of water-quality studies, 1992-95
From 1992 through 1995, nearly 1,200 water-quality samples from about 500 sites were collected, processed, and analyzed for the U.S. Geological Survey's (USGS) National Water-Quality Assessment (NAWQA) Program in the Lower Susquehanna River Basin in Pennsylvania and Maryland. Sites were selected and samples were collected for 28 integrated water-quality studies designed to provide a...

Herbicide concentrations in and loads transported by the Conestoga River and Pequea Creek, Lancaster County, Pennsylvania, 1992-95 Herbicide concentrations in and loads transported by the Conestoga River and Pequea Creek, Lancaster County, Pennsylvania, 1992-95
Water samples were collected from four streams in Lancaster County from 1992 through 1995 and analyzed for selected herbicides. Samples were collected from the Little Conestoga Creek near Churchtown, Mill Creek (a tributary to the Conestoga River) at Elshelman Mill Road near Lyndon, the Conestoga River at Conestoga, and Pequea Creek at Martic Forge. Most samples were collected from...

Metals, pesticides, and semivolatile organic compounds in sediment in Valley Forge National Historical Park, Montgomery County, Pennsylvania Metals, pesticides, and semivolatile organic compounds in sediment in Valley Forge National Historical Park, Montgomery County, Pennsylvania
The Schuylkill River flows through Valley Forge National Historical Park in Lower Providence and West Norriton Townships in Montgomery County, Pa. The concentration of selected metals, pesticides, semivolatile organic compounds, and total carbon in stream-bottom sediments from Valley Forge National Historical Park were determined for samples collected once at 12 sites in and around the...

Modified level II streambed-scour analysis for structure I-70-35-5245 crossing Big Walnut Creek in Putnam County, Indiana Modified level II streambed-scour analysis for structure I-70-35-5245 crossing Big Walnut Creek in Putnam County, Indiana
Level II scour evaluations follow a process in which hydrologic, hydraulic, and sedimenttransport data are evaluated to calculate the depth of scour that may result when a given discharge is routed through a bridge opening. The results of the modified Level II analysis for structure 1-70-35-5245 on Interstate 70 crossing Big Walnut Creek in Pumam.County, Indiana, are presented. The site...

The wind-forced response on a buoyant coastal current: Observations of the western Gulf of Maine plume The wind-forced response on a buoyant coastal current: Observations of the western Gulf of Maine plume
The Freshwater plume in the western Gulf of Maine is being studied as part of an interdisciplinary investigation of the physical transport of a toxic alga. A field program was conducted in the springs of 1993 and 1994 to map the spatial and temporal patterns of salinity, currents and algal toxicity. The observations suggest that the plume's cross-shore structure varies markedly as a...
