Estimating Concentrations of Road-Salt Constituents in Highway-Runoff from Measurements of Specific Conductance Estimating Concentrations of Road-Salt Constituents in Highway-Runoff from Measurements of Specific Conductance
Discrete or composite samples of highway runoff may not adequately represent in-storm water-quality fluctuations because continuous records of water stage, specific conductance, pH, and temperature of the runoff indicate that these properties fluctuate substantially during a storm. Continuous records of water-quality properties can be used to maximize the information obtained about the...

Relations of surface-water quality to streamflow in the Wallkill and upper Delaware River basins, New Jersey and vicinity, water years 1976-93 Relations of surface-water quality to streamflow in the Wallkill and upper Delaware River basins, New Jersey and vicinity, water years 1976-93
Relations of water quality to streamflow were determined for 18 water-quality constituents at 18 surface-water stations within the drainage basins of the Wallkill and upper Delaware Rivers in New Jersey and vicinity for water years 1976-93. Surface-water-quality and streamflow data were evaluated for trends (through time) in constituent concentrations during high and low flows, and...

Lithostratigraphy, geophysics, biostratigraphy, and strontium-isotope stratigraphy of the surficial aquifer system of eastern Collier County and northern Monroe County, Florida Lithostratigraphy, geophysics, biostratigraphy, and strontium-isotope stratigraphy of the surficial aquifer system of eastern Collier County and northern Monroe County, Florida
In 1997, ten cores were drilled in eastern Collier County and northern Monroe County, within the limits of the Big Cypress National Preserve. These cores represent a continuation of the study of seven cores in western Collier County begun in 1996 and reported in Weedman and others (1997) and Edwards and others (1998). This joint U.S. Geological Survey and Florida Geological Survey...

USGS ground-water flow model : an essential tool for managing the water supply of the Virginia Coastal Plain USGS ground-water flow model : an essential tool for managing the water supply of the Virginia Coastal Plain
Virginia needs a reliable water supply to sustain its growing population and expanding economy. In 1990, the aquifers in the Coastal Plain supplied about 100 million gallons per day (mgd) to the citizens, businesses, and industries of Virginia. It is estimated that by the year 2000, demand will increase by another 10 mgd and likely will continue to increase in future years. Ground water...

Comparative microhabitat use of ecologically similar benthic fishes Comparative microhabitat use of ecologically similar benthic fishes
Although benthic insectivorous fishes such as darters and sculpins represent a significant component of riffle communities, few studies have compared the habitat use of these non-related but ecologically similar fishes. The objectives of this study were to examine the habitat use of Etheostoma olmstedi (tessellated darter) compared to Cottus bairdi (mottled sculpin) in Nescopeck Creek...

Physical, chemical, and biological data for selected streams in Chester County, Pennsylvania, 1981-94 Physical, chemical, and biological data for selected streams in Chester County, Pennsylvania, 1981-94
Physical, chemical, and biological data were collected at 51 sampling sites in Chester County, Pa., from 1970 through 1994 as part of the Stream Conditions of Chester County Program. This report presents data collected from 1981 through 1994. Physical data include water temperature, instantaneous stream discharge, pH, alkalinity, specific conductance, and dissolved oxygen. Chemical data...
