Water quality

The chemical, physical, and biological characteristics of water, usually in respect to its suitability for a particular purpose.
This category is also used for dissolved constituents, dissolved contaminants, and water-quality.

Results listed by similarity [list alphabetically]
Hydrogeochemical investigations of historic mining districts, central western slope of Colorado, including influence on surface-water quality

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

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

Geochemical data for stream sediment, surface-water, rock, precipitate, and vegetation samples from Red Mountain

Miscellaneous geochemical data from waters in the Upper Animas River Watershed, Colorado

This report releases data for waters in which naturally occurring acid-rock drainage occurs but acid-mine drainage from historical mining continues to contribute dissolved metals further degrading preexisting water quality.

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

Geochemical data for stream water, sediments, and mine tailings in this area

Spring runoff water-chemistry data from the Standard Mine and Elk Creek, Gunnison County, Colorado, 2010

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.

Surface-water hydrology and quality at the Pike Hill Superfund Site, Corinth, Vermont, October 2004 to December 2005

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.

Temporal Chemical Data for Sediment, Water, and Biological Samples from the Lava Cap Mine Superfund Site, Nevada County, California-2006-2008

This report is a compilation of water and sediment chemical data generated by the USGS study of indigenous, arsenic-sequestering microbial communities. A total of 9 synoptic sampling efforts conducted at specific sites are described.

Relation of arsenic, iron, and manganese in ground water to aquifer type, bedrock lithogeochemistry, and land use in the New England coastal basins

Geochemical data for groundwater from a variety of geologic settings.

Uranium in surface waters and sediments affected by historical mining in the Denver West 1:100,000 quadrangle, Colorado

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

Acid-rock drainage at Skytop, Centre County, Pennsylvania, 2004

Aquatic assessment of the Ely Copper Mine Superfund site, Vershire, Vermont

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

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.

Characterization of mine waste at the Elizabeth copper mine, Orange County, Vermont

Preliminary information about the concentration, spatial distribution and mineral hosting of metals and other elements in solid materials at the Elizabeth copper mine after 50 years (or more) of weathering and oxidation.

Geochemical characterization of drainage prior to reclamation at the abandoned Valzinco mine, Spotsylvania County, Virginia

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

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

Linking geology and health sciences to assess childhood lead poisoning from artisanal gold mining in Nigeria

Approximately 400 young children have died and thousands more are affected. This study clarifies lead sources and exposure pathways, identifies other toxicants of concern and people at risk, and examines potential for similar lead poisoning globally.

Mercury release from the Rathburn Mine, Petray Mine, and Bear Valley saline springs, Colusa County, California 2004-2006

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.

Occurrence and variability of mining-related lead and zinc in the Spring River flood plain and tributary flood plains, Cherokee County, Kansas, 2009--11

One hundred years of historical mining has resulted in substantial ongoing input of cadmium, lead, and zinc into the environment. This surficial-soil sampling and coring study provides information needed to support remediation efforts.
