Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1991-92 in Fort Bend County and adjacent areas, Texas Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1991-92 in Fort Bend County and adjacent areas, Texas
This report was prepared in cooperation with the Fort Bend Subsidence District, and presents data on water-level changes during 1991-92 in the Chicot and Evangeline aquifer (fig. 1-2) in Fort Bend County. Water-level change maps were prepared previously by Locke (1990),and Locke and Barbie (1991), for both aquifers, and by Wesselman (1972) for the Chicot aquifer.

Availability and quality of water from the alluvial, glacial-drift, and Dakota aquifers and water use in southwest Iowa Availability and quality of water from the alluvial, glacial-drift, and Dakota aquifers and water use in southwest Iowa
A ground-water resources investigation was conducted in southwest Iowa to describe the availability, quality, and use of water from the alluvial, glacial-drift, and Dakota aquifers in a nine-county area. Historical water quality was examined for each aquifer, and water samples were collected for major ions, trace metals, radionuclides, and selected pesticides. Selected aspects of surface...

Summary of hydrologic data for the San Gabriel River basin and Edwards Aquifer, Georgetown area, Texas, water year 1990 Summary of hydrologic data for the San Gabriel River basin and Edwards Aquifer, Georgetown area, Texas, water year 1990
The Edwards aquifer is the principal source of freshwater for municipal, domestic, and industrial users in the Georgetown area. Other sources of freshwater are Lake Georgetown and the streams draining the San Gabriel River basin. Lake Georgetown, located on the North Fork San Gabriel River west of Georgetown, is a freshwater supply for some municipalities in the area. Water in the San...

Water-quality data from continuously monitored sites in the Pamlico and Neuse River estuaries, North Carolina, 1990-91 Water-quality data from continuously monitored sites in the Pamlico and Neuse River estuaries, North Carolina, 1990-91
Water quality measurements were made at six sites in or near North Carolina's Pamlico River estuary and at five sites in or near the Neuse River estuary. Measurements taken at 15-minute intervals included near-surface and near-bottom specific conductance; near-surface water temperature; and near-surface, mid-depth, and near-bottom dissolved-oxygen concentrations. In the Pamlico River...

Water quality of the Edwards Aquifer and streams recharging the aquifer in the San Antonio region, Texas Water quality of the Edwards Aquifer and streams recharging the aquifer in the San Antonio region, Texas
The Edwards aquifer in south-central Texas is one of the most productive and most important aquifers in the State, with an average annual discharge of about 608,000 acre-ft of water during 1932-82 (Reeves and Ozuna, 1985). The Edwards aquifer is the principal source of water for municipal, industrial, and irrigation use in all or parts of five counties- Bexar, Comal, hays, Medina, and...

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...

The use of tumors in wild populations of fish to assess ecosystem health The use of tumors in wild populations of fish to assess ecosystem health
Evidence has linked toxicants in aquatic systems with cancer in fish and population level effects on species. Thus some types of tumors may be useful monitors of ecosystem health, at least as affected by genotoxins and promoters. However, tumors caused by purely genetic mechanisms or by virus would not be good indicators. Only neoplasms which have chemicals as a portion of their etiology...
