Development of cytochromes P450 in avian species as a biomarker for environmental contaminant exposure and effect: Procedures and baseline values Development of cytochromes P450 in avian species as a biomarker for environmental contaminant exposure and effect: Procedures and baseline values
As in mammals and fish, birds respond to many environmental contaminants with induction of hepatic cytochromes P450. In order to monitor cytchromes P450 in specific avian species, for assessing the status of that species or the habitat it utilizes, it is necessary to have background information on the appropriate assay conditions and the responsiveness of cytochrome P450 induction in...

Borehole geophysical logging for water-resources investigations in Pennsylvania Borehole geophysical logging for water-resources investigations in Pennsylvania
Borehole geophysical logging is a procedure to collect and transmit specific information about the geologic formations penetrated by a well by raising and lowering a set of probes or sondes that contain water-tight instruments in the well. The data collected can be used to determine general formation geology, fracture distribution, vertical borehole flow, and water-yielding capabilities.

Trends in surface-water quality in Connecticut, 1969-88 Trends in surface-water quality in Connecticut, 1969-88
Surface-water-quality data from selected monitoring stations in Connecticut were analyzed for trend, using the Seasonal Kendall test, for water years 1969-88, 1975-88, and 1981-88. The number of constituents and stations evaluated varied with the different time periods. The 39 monitoring stations included 26 freshwater streams with associated discharge data, 7 tidally affected streams, 4...

Hydrogeology and ground-water quality of Valley Forge National Historical Park, Montgomery County, Pennsylvania Hydrogeology and ground-water quality of Valley Forge National Historical Park, Montgomery County, Pennsylvania
Valley Forge National Historical Park is just southwest of the Commodore Semiconductor Group (CSG) National Priorities List (Superfund) Site, a source of volatile organic compounds (VOC's) in ground water. The 7.5-square-mile study area includes the part of the park in Lower Providence and West Norriton Townships in Montgomery County, Pa., and surrounding vicinity. The park is underlain...

HYSEP: A Computer Program for Streamflow Hydrograph Separation and Analysis HYSEP: A Computer Program for Streamflow Hydrograph Separation and Analysis
HYSEP is a computer program that can be used to separate a streamflow hydrograph into base-flow and surface-runoff components. The base-flow component has traditionally been associated with ground-water discharge and the surface-runoff component with precipitation that enters the stream as overland runoff. HYSEP includes three methods of hydrograph separation that are referred to in the...

Altitude and configuration of the potentiometric surface in the crystalline and metasedimentary rocks in Birmingham, Newlin, Pennsbury, and Pocopson Townships and parts of East Marlborough and Kennett Townships, Chester County, Pennsylvania, June 1994 thr Altitude and configuration of the potentiometric surface in the crystalline and metasedimentary rocks in Birmingham, Newlin, Pennsbury, and Pocopson Townships and parts of East Marlborough and Kennett Townships, Chester County, Pennsylvania, June 1994 thr
A map showing ground-water levels in crystalline and metasedimentary rocks in Birmingham, Newlin, Pennsbury, and Pocopson Townships and parts of East Marlborough and Kennett Townships, Chester County, Pennsylvania, was constructed from water levels measured in wells from June 1994 through November 1995. Pre-1994 measurements were incorporated on the map to provide control in areas where...
