The use of freshwater and saltwater animals to distinguish between the toxic effects of salinity and contaminants in irrigation drain water The use of freshwater and saltwater animals to distinguish between the toxic effects of salinity and contaminants in irrigation drain water
Irrigation drain waters entering Stillwater Wildlife Management Area (SWMA) in south-western Nevada contain elevated levels of salinity and several inorganic contaminants (As, B, Cu, Li, Mo, and Sr). Mortalities of fish and waterfowl at the management area are believed to be associated with the poor water quality of the drains. The objective of the present study was to use fresh-water...

Selenium and other elements in freshwater fishes from the irrigated San Joaquin Valley, California Selenium and other elements in freshwater fishes from the irrigated San Joaquin Valley, California
Arsenic (As), chromium (Cr), mercury (Hg), and selenium (Se) were measured in composite whole-body samples of five fishes — bluegill (Lepomis macrochirus), common carp (Cyprinus carpio), mosquitofish (Gambusia affinis), largemouth bass (Micropterus salmoides), and Sacramento blackfish (Orthodon microlepidotus) — from the San Joaquin River system to determine if concentrations were...

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...

The ground-water-level monitoring network in Iowa The ground-water-level monitoring network in Iowa
The ground-water-level monitoring network in Iowa consists of 202 wells completed in the principal bedrock and surficial aquifers that supply ground water to numerous users throughout the State. The bedrock aquifers include the Cambrian-Ordovician aquifer system, the Silurian-Devonian aquifer, the Mississippian aquifer, localized Pennsylvanian aquifers, and the Dakota aquifer. The...

Comparison of solid-phase and pore-water approaches for assessing the quality of marine and estuarine sediments Comparison of solid-phase and pore-water approaches for assessing the quality of marine and estuarine sediments
As part of our continuing evaluation of the pore-water approach for assessing sediment quality, we made a series of side-by-side comparisons between the standard 10-day amphipod whole sediment test with the corophiid Grandidierella japonica and a suite of tests using pore water extracted from the same sediments. the pore-water tests evaluated were the sea urchin (Arbacia punctulata)...
