Nutrient concentrations and yields in undeveloped stream basins of the United States Nutrient concentrations and yields in undeveloped stream basins of the United States
Data from 85 sites across the United States were used to estimate concentrations and yields of selected nutrients in streams draining relatively undeveloped basins. Flow-weighted concentrations during 1990-1995 were generally low with median basin concentrations of 0.020, 0.087, 0.26, 0.010, and 0.022 milligrams per liter (mg/L) for ammonia as N, nitrate as N, total nitrogen...

Environmental characteristics and water quality of hydrologic benchmark network stations in the Midwestern United States, 1963-95 Environmental characteristics and water quality of hydrologic benchmark network stations in the Midwestern United States, 1963-95
This report describes the environmental characteristics and water quality at 14 benchmark basins in the Midwestern United States. The information in this report was compiled to aid in the application and interpretation of historical water-quality data collected by the U.S. Geological Survey Hydrologic Benchmark Network program. The streams discussed in this report drain either forested...

Determination of chemical-constituent loads during base-flow and storm-runoff conditions near historical mines in Prospect Gulch, upper Animas River watershed, southwestern Colorado Determination of chemical-constituent loads during base-flow and storm-runoff conditions near historical mines in Prospect Gulch, upper Animas River watershed, southwestern Colorado
Prospect Gulch is a major source of iron, aluminum, zinc, and other metals to Cement Creek. Information is needed to prioritize remediation and develop strategies for cleanup of historical abandoned mine sites in Prospect Gulch. Chemical-constituent loads were determined in Prospect Gulch, a high-elevation alpine stream in southwestern Colorado that is affected by natural acid drainage...

Environmental characteristics and water quality of hydrologic benchmark network stations in the Eastern United States, 1963-95 Environmental characteristics and water quality of hydrologic benchmark network stations in the Eastern United States, 1963-95
The information in this report was compiled to aid in the application and interpretation of historical water-quality data collected as part of the U.S. Geological Survey Hydrologic Benchmark Network program, which was established in 1963 to provide long-term measurements of streamflow and water quality in areas that are minimally affected by human activities. This report describes the
