Surface water quality
Chemical, physical, and biological characteristics of water in lakes, rivers, or streams related to its fitness for use.
- Hydrogeochemical investigations of historic mining districts, central western slope of Colorado, including influence on surface-water quality [New Window]
- Geochemical analysis of mine dumps, mill tailings, mine drainage, and surface waters indicate contamination from these historic mines is generally less than that asserted or suggested by some geochemical models
- Surface-water hydrology and quality at the Pike Hill Superfund Site, Corinth, Vermont, October 2004 to December 2005 [New Window]
- Synoptic water-quality and benthic macroinvertebrate sampling at 14 stream sites to characterize the quality of surface water in the watershed on a seasonal and spatial basis, as well as to assess the effects of wetlands on water quality.
- Geochemical data for stream-sediment, surface-water, rock, and vegetation samples from Red Mountain (Dry Creek), an unmined volcanogenic massive sulfide deposit in the Bonnifield district, Alaska Range, east-central Alaska [New Window]
- Geochemical data for stream sediment, surface-water, rock, precipitate, and vegetation samples from Red Mountain
- Quality of water and sediment in streams affected by historical mining, and quality of mine tailings, in the Rio Grande/Río Bravo basin, Big Bend area of the United States and Mexico, August 2002 [New Window]
- Geochemical data for stream water, sediments, and mine tailings in this area
- Uranium in surface waters and sediments affected by historical mining in the Denver West 1:100,000 quadrangle, Colorado [New Window]
- Geochemical analysis of stream waters and sediments in mountainous areas immediately west of Denver, Colorado, to evaluate the concentration and distribution of uranium-bearing acid drainage originating from historical mines
- Spring runoff water-chemistry data from the Standard Mine and Elk Creek, Gunnison County, Colorado, 2010 [New Window]
- Periodic sampling of water during the spring of 2010 was carried out to understand the range and timing of variation in pH and metal concentration, and help evaluate variation in water quality during spring runoff.
- Acid-rock drainage at Skytop, Centre County, Pennsylvania, 2004 [New Window]
- Aquatic assessment of the Ely Copper Mine Superfund site, Vershire, Vermont [New Window]
- A wide variety of geochemical analyses show strong local impact on water quality in this area of historical copper mining.
- Case study of the environmental signature of a recently abandoned, carbonate-hosted replacement deposit: The Clayton Mine, Idaho [New Window]
- Multi-element geochemical analysis of host rock, ore, mine waste, flotation-mill tailings, slag, stream sediments, creek and adit waters, and leachates of mine waste and mill tailings.
- Geochemical characterization of drainage prior to reclamation at the abandoned Valzinco mine, Spotsylvania County, Virginia [New Window]
- Geochemical analysis of water samples to provide a pre-reclamation assessment of seasonal variations of acid and metal concentrations in Knight's Branch help evaluate the reclamation project.
- Geochemical Characterization of Mine Waste, Mine Drainage, and Stream Sediments at the Pike Hill Copper Mine Superfund Site, Orange County, Vermont: U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency [New Window]
- Sampling procedures, analytical methodologies, and results to assess the potential for mine waste and drainage to have an adverse impact on aquatic ecosystems, on drinking- water supplies, and to human health
- Mercury release from the Rathburn Mine, Petray Mine, and Bear Valley saline springs, Colusa County, California 2004-2006 [New Window]
- Summary of data obtained from field sampling of mine tailings and waste rock and water and sediment in regional springs and tributaries that drain from the mine area into Bear Creek. Ground-water springs are also potential sources of mercury here.
