Survival of striped bass larvae and yearlings in relation to contaminants and water quality in the upper Chesapeake Bay
This study was designed to evaluate survival of striped bass yolk-sac larvae and yearlings at three locations in their natural spawning habitat in the upper Chesapeake Bay (Chesapeake and Delaware Canal) using “in-situ” chambers; correlate larval and yearling survival with the presence of 11 water quality parameters, 10 inorganic contaminants and 21 organic contaminants and assess histological eff

Interactions among dietary minerals, arginine and lysine in rainbow trout (Salmo gairdneri)
Studies were conducted to determine whether interactions occur among dietary lysine, arginine and monovalent minerals in rainbow trout. In one experiment, rainbow trout fingerlings were fed diets containing three levels of lysine (2.4, 3.1 and 3.8 g per 100 g diet), two levels of arginine (1.7 and 2.5 g per 100 g diet) and two mixtures of Na+ K+ and Cl in a 3×2×2 factorial design. The mixtures var

Surface-water quality in Pequea Creek basin, Pennsylvania, 1977-79
A study of the Pequea Creek basin was conducted by the U.S. Geological Survey, in cooperation with the Susquehanna River Basin Commission and the EPA from February 1977 through March 1979. Pequea Creek drains an intensive agricultural area of 154 sq mi in southeastern Pennsylvania, and enters the Susquehanna River 30 mi north of the Chesapeake Bay. The study included measurement of streamflow and

Effect of urbanization on the water resources of eastern Chester County, Pennsylvania
The effects of human activity on the water resources of a 207-square-mile area of eastern Chester County was evaluated. The most serious consequence of urbanization is the contamination of ground water by volatile organic compounds, which were detected in 39 percent of the 70 wells sampled. As many as nine compounds were found in one water sample, and the concentration of total volatile organic co

Quality of water in mines in the Western Middle Coal Field, Anthracite Region, east-central Pennsylvania
The quality of mine water in the 75 sq-mi Western Middle anthracite field, Pennsylvania was determined by sampling discharges and boreholes at 60 abandoned and flooded mines during 1975-78. The Vulcan-Buck Mountain mine, east-northeast of Mahanoy City, contains an estimated 6,100 acre-ft of water with a specific conductance of 380 to 460 micromhos and a pH of 4.4 to 4.6 units. Twenty-two mines are
