Influence of fluoride on aluminum toxicity to Atlantic salmon (Salmo salar) Influence of fluoride on aluminum toxicity to Atlantic salmon (Salmo salar)
Atlantic salmon (Salmo salar) alevins were exposed to various aluminum (0–4700 μg/L) and four fluoride (0–500 μg/L) concentrations at two pH values (5.5 and 6.5) for 4- and 30-d periods. In the 4-d tests, aluminum with fluoride was less toxic at pH 6.5 than at pH 5.5, whereas without fluoride, pH had no effect. In the 30-d test, mortality in all treatments was 17–21% at pH 5.5, but only...

Geologic framework and hydrogeologic characteristics of the Edwards Aquifer outcrop, Hays County, Texas Geologic framework and hydrogeologic characteristics of the Edwards Aquifer outcrop, Hays County, Texas
All of the hydrogeologic subdivisions within the Edwards aquifer outcrop in Hays County have some porosity and permeability. The most porous and permeable appear to be hydrogeologic subdivision VI, the Kirschberg evaporite member of the Kainer Formation; hydrogeologic subdivision III, the leached and collapsed members, undivided; and hydrogeologic subdivision II, the cyclic and marine...

Agricultural chemicals in ground and surface water in a small watershed in Clayton County, Iowa, 1988-91 Agricultural chemicals in ground and surface water in a small watershed in Clayton County, Iowa, 1988-91
An investigation was conducted from October 1988 through September 1991 to (1) describe the quality of water in shallow, unconsolidated materials in the 1.09-square-mile Deer Creek watershed in Clayton County, Iowa, and to (2) define the quantity and seasonal distribution of selected agricultural chemicals in water from this watershed. Surficial unconsolidated aquifer materials that...

Estimated withdrawals and use of freshwater in Vermont, 1990 Estimated withdrawals and use of freshwater in Vermont, 1990
Estimated freshwater withdrawals during 1990 in Vermont totaled about 632 million gallons per day. The largest withdrawals were for thermoelectric- power generation (82 percent), industrial use (7 percent), and public supply (6 percent). Most withdrawals, 587 million gallons per day, were made from surface-water sources as compared to 44.9 million gallons per day from ground-water...

Flood of 1993—Mississippi River near the Jefferson National Expansion Memorial (Arch), St. Louis, Missouri Flood of 1993—Mississippi River near the Jefferson National Expansion Memorial (Arch), St. Louis, Missouri
River-flow data have been collected on the Mississippi River at St. Louis near the Jefferson National Expansion Memorial (Arch) since 1861. Water at this location is excess river flow from 13 States and part of Canada (drainage area of about 697,000 square miles). Many disaster conditions, including floods and droughts, have affected this area; however, the flood of 1993 will be...

Water-quality assessment of the Trinity River Basin, Texas— Analysis of available information on nutrients and suspended sediment, 1974-91 Water-quality assessment of the Trinity River Basin, Texas— Analysis of available information on nutrients and suspended sediment, 1974-91
The U.S. Geological Survey is conducting an assessment of water quality in the Trinity River Basin as part of the National Water-Quality Assessment Program. During the planning phase of this study, existing information on nutrients and suspended sediment was compiled and analyzed. A total of about 5,700 water-quality samples were analyzed from local, State, and Federal agencies. Of these...
