Water-quality assessment of south-central Texas — Descriptions and comparisons of nutrients, pesticides, and volatile organic compounds at three intensive fixed sites, 1996-98 Water-quality assessment of south-central Texas — Descriptions and comparisons of nutrients, pesticides, and volatile organic compounds at three intensive fixed sites, 1996-98
Water-quality samples were collected during April 1996-April 1998 at three intensive fixed sites in the San Antonio region of the South-Central Texas study unit as part of the U.S. Geological Survey National Water-Quality Assessment Program. The sampling strategy for the intensive fixed-site assessment is centered on obtaining information about the occurrence and seasonal patterns of...

Hypothesis of historical effects from selenium on endangered fish in the Colorado River basin Hypothesis of historical effects from selenium on endangered fish in the Colorado River basin
Anthropogenic selenium contamination of aquatic ecosystems was first associated with cooling reservoirs of coal-fired power plants in the late 1970s, and later with drainage water from agricultural irrigation activities in the 1980s. In the 1990s, selenium contamination has been raised as a concern in the recovery of currently endangered fish in the Colorado River system. Widespread...

Shallow ground-water quality in the Coastal Plain of Columbia, South Carolina, 1996 Shallow ground-water quality in the Coastal Plain of Columbia, South Carolina, 1996
As part of the National Water-Quality Assessment (NAWQA) Program, the U.S. Geological Survey (USGS) oversaw the installation of 30 shallow monitoring wells in the Columbia, South Carolina metropolitan area. The ground water sampled from these wells was used to study the recent effects of human activities on shallow ground water in an urban setting. Well locations were selected in...

Cumulative index to chemicals and to common and scientific names of species listed in Contaminant Hazard Reviews 1 through 34 Cumulative index to chemicals and to common and scientific names of species listed in Contaminant Hazard Reviews 1 through 34
The Contaminant Hazard Review (CHR) series--sponsored by the U.S. Geological Survey, Patuxent Wildlife Research Center--synthesizes ecotoxicological data for selected environmental contaminants, with emphasis on hazards to native species of flora and fauna. From 1985 through 1998, 34 reviews were published in various report series of the U.S. Department of the Interior on agricultural...

Nitrate in groundwater of the midwestern United States: A regional investigation on relations to land use and soil properties Nitrate in groundwater of the midwestern United States: A regional investigation on relations to land use and soil properties
The intense application of nitrogen-fertilizer to cropland in the midwestern United States has created concern about nitrate contamination of the region's aquifers. Since 1991, the US Geological Survey has used a network of 303 wells to investigate the regional distribution of nitrate in near-surface aquifers of the midwestern United States. Detailed land use and soil data were compiled...

Movements of adult chinook salmon during spawning migration in a metals-contaminated system, Coeur d'Alene River, Idaho Movements of adult chinook salmon during spawning migration in a metals-contaminated system, Coeur d'Alene River, Idaho
Spawning migration of adult male chinook salmon Oncorhynchus tshawytscha was monitored by radio telemetry to determine their response to the presence of metals contamination in the South Fork of the Coeur d'Alene River, Idaho. The North Fork of the Coeur d'Alene River is relatively free of metals contamination and was used as a control. In all, 45 chinook salmon were transported from...

Assessing groundwater vulnerability to agrichemical contamination in the Midwest US Assessing groundwater vulnerability to agrichemical contamination in the Midwest US
Agrichemicals (herbicides and nitrate) are significant sources of diffuse pollution to groundwater. Indirect methods are needed to assess the potential for groundwater contamination by diffuse sources because groundwater monitoring is too costly to adequately define the geographic extent of contamination at a regional or national scale. This paper presents examples of the application of

Assessing biological effects from highway-runoff constituents Assessing biological effects from highway-runoff constituents
Increased emphasis on evaluation of nonpoint-source pollution has intensified the need for techniques that can be used to discern the toxicological effects of complex chemical mixtures. In response, the use of biological assessment techniques is receiving increased regulatory emphasis. When applied with documented habitat assessment and chemical analysis, these techniques can increase...
