Evaluation of effects caused by high copper concentrations in Torch Lake, Michigan, on reproduction of yellow perch Evaluation of effects caused by high copper concentrations in Torch Lake, Michigan, on reproduction of yellow perch
Elevated concentrations of copper are present in Torch Lake, Michigan, an Environmental Protection Agency Superfund site. The sauger (Stizostedion canadense) population in Torch Lake has been extirpated and walleye (Stizostedion vitreum) populations are maintained by stocking. We used yellow perch (Perca flavescens) to determine if chronic exposure to elevated copper concentrations has...

Fate and pathways of injection-well effluent in the Florida Keys Fate and pathways of injection-well effluent in the Florida Keys
Twenty-four wells (21 locations) were core drilled into the limestone beneath the Keys, reef tract, and outer reefs to determine if sewage effluents injected in Class V wells onshore are reaching offshore reef areas via underground flow. These wells were fitted with PVC casings and well screens and were sampled every three months for a period of one year. Analyses showed consistent...

Analysis of data from test-well sites along the downdip limit of freshwater in the Edwards Aquifer, San Antonio, Texas, 1985-87 Analysis of data from test-well sites along the downdip limit of freshwater in the Edwards Aquifer, San Antonio, Texas, 1985-87
Many researchers have studied the downdip limit of freshwater in the Edwards aquifer or various aspects of the saline-water zone and its relation to the freshwater zone. These studies were summarized and used to synthesize a consistent hydrologic and geochemical framework from which to interpret data from field studies. The concept derived from the previous work on the downdip limit of...

National Water-Quality Assessment Program - South-Central Texas National Water-Quality Assessment Program - South-Central Texas
In 1991, the U.S. Geological Survey (USGS), Department of the Interior, began a National Water-Quality Assessment (NAWQA) Program. The long-term goals of the NAWQA Program are to describe the status of and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources and to identify the major natural and human factors that affect the quality of...
