Water-supply potential of major streams and the upper Floridan Aquifer in the vicinity of Savannah, Georgia Water-supply potential of major streams and the upper Floridan Aquifer in the vicinity of Savannah, Georgia
Long-term pumping from the Upper Floridan aquifer in the Savannah, Georgia, area has lowered ground-water levels, resulting in increased salinity of ground water by seawater encroachment at Hilton Head Island, S.C., and by saltwater intrusion at Brunswick, Ga. Increased pumpage could cause further salinization of the ground-water resources. The Savannah and Ogeechee Rivers can be...

Two-dimensional circulation modeling of the Pamlico River estuary, North Carolina Two-dimensional circulation modeling of the Pamlico River estuary, North Carolina
A two dimensional, vertically averaged, unsteady flow model was applied to a 50- kilometer reach of the Pamlico River estuary, North Carolina. The model computational grid, which consists of about 16,000 square cells, each 200 meters on a side, was developed from more than one million depth soundings. Information from a comprehensive data-collection network, including six water-level...

An evaluation of a genotoxicity assay with liver s9 for activation and luminescent bacteria for detection An evaluation of a genotoxicity assay with liver s9 for activation and luminescent bacteria for detection
A new short-term in vitro genotoxicity assay with marine bioluminescent bacteria was evaluated for sensitivity and cost. Known under the trade name of Mutatox™, this assay is a simple and rapid screening tool that detects DNA-damaging substances (genotoxins) by measuring light output from an isolated dark mutant strain of the luminescent bacterium Photobacterium phosphoreum. A positive...

Cadmium and mercury in emergent mayflies (Hexagenia bilineata) from the upper Mississippi River Cadmium and mercury in emergent mayflies (Hexagenia bilineata) from the upper Mississippi River
Burrowing mayflies (Hexagenia bilineata) were analyzed to assess longitudinal patterns in their cadmium and mercury content along the upper Mississippi River. Emergent mayflies (subimagoes and imagoes) were collected in 1988 at 34 sites (25 navigation pools), extending 1260 km from Little Falls, Minnesota, downstream to St. Louis, Missouri. Cadmium concentrations in composite samples of...

Techniques for estimating 7-day, 10-year low-flow characteristics for ungaged sites on streams in Mississippi Techniques for estimating 7-day, 10-year low-flow characteristics for ungaged sites on streams in Mississippi
Mississippi State water laws require that the 7-day, 10-year low-flow characteristic (7Q10) of streams be used as a criterion for issuing wastedischarge permits to dischargers to streams and for limiting withdrawals of water from streams. This report presents techniques for estimating the 7Q10 for ungaged sites on streams in Mississippi based on the availability of baseflow discharge...

Effects of dried wastewater-treatment sludge application on ground-water quality in South Dade County, Florida Effects of dried wastewater-treatment sludge application on ground-water quality in South Dade County, Florida
Four test fields in the south Dade agricultural area were studied to determine the effects of sludge application on ground-water quality. Two fields had been cultivated for 10 years or more, and two had not been farmed for at least 10 years. The fields were representative of the area's two soil types (Rockdale and Perrine marl) and two major crop types (row crops and groves). Before the
