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.
Aqueous geochemical data from the analysis of stream-water samples collected in June and August 2008--Taylor Mountains 1:250,000- and Dillingham D-4 1:63,360-scale quadrangles, Alaska
Measurements on 92 samples, including pH, conductivity, water temperature, major cation and anion concentrations, and trace-element concentrations.
Aqueous geochemical data from the analysis of stream-water samples collected in June and July 2006-Taylor Mountains 1:250,00-scale quadrangle, Alaska
Analyses of 72 water samples include pH, conductivity, water temperature, major cation and anion concentrations, trace-element concentrations, and dissolved organic-carbon concentrations.
Chemical analyses of soils and other surficial materials of the conterminous US
Geochemistry of soils and other regoliths collected and analyzed by Hans Shacklette and colleagues from 1958 until about 1976.
Depositional Setting and Geochemistry of Phosphorites and Metalliferous Black Shales in the Carboniferous-Permian Lisburne Group, Northern Alaska
The purpose of this paper is to present new sedimentological, paleontological, and geochemical data that allow us to define the geographic and stratigraphic extent and depositional setting of these temporally unusual phosphorites.
PDF Environmental characteristics of the abandoned Greenwood Mine area, Prince William Forest Park, Virginia; implications for mercury geochemistry
Water quality data for the area include pH, dissolved oxygen, alkalinity, total acid soluble and dissolved major and trace element concentrations for sites around the mine workings.
Geochemical and mineral maps from soils of the conterminous United States: interactive web site
Interactive web site showing geochemical and mineralogical maps along with a histogram, boxplot, and empirical cumulative distribution function plot for each element or mineral whose data are provided in DS-801
Geochemical data from groundwater at the proposed Dewey Burdock uranium in-situ recovery mine, Edgemont, South Dakota
Groundwater geochemistry data from samples that were collected in June 2011 to better understand the hydrogeologic system in the area surrounding the proposed mine site.
Geochemical data from waters in Prospect Gulch, San Juan County, Colorado, that span pre- and post-Lark Mine remediation
Water samples near this abandoned mine were analyzed for specific conductance, pH, temperature, and dissolved oxygen with handheld field meters, and metals were analyzed using inductively coupled plasma-mass spectrometry.
Geochemical Results of Lysimeter Sampling at the Manning Canyon Repository in the Mercur Mining District, Utah
This report presents chemical characteristics of transient unsaturated-zone water collected by lysimeter from the Manning Canyon repository site in Utah. Data collected by U.S. Geological Survey and U.S. Department of the Interior, Bureau of Land Manageme
Geochemistry of sediments in the US from the PLUTO database
Geochemical data for unconsolidated sediments (stream sediments, lake sediments, etc.) collected in the US and analyzed by the USGS. These data were originally entered in the PLUTO database, which is now merged into the National Geochemistry Database.
Geochemistry of soils in the US from the PLUTO database
Geochemical data for soils collected in the United States and analyzed by the USGS. The data were originally entered into the in-house PLUTO database. This is a subset of DDS-47.
Geochemistry of stream sediments in the US from the NURE-HSSR database
National-scale geochemical analysis of stream sediments and soils in the US collected and analyzed under the National Uranium Resource Evaluation program.
Geochemistry of water samples in the US from the NURE-HSSR database
National-scale geochemical analysis of water samples in the US collected and analyzed under the National Uranium Resource Evaluation program.
Geospatial database for regional environmental assessment of central Colorado
Study focusing on the effects of historical mining on Forest Service lands in this area.
Historical zinc smelting in New Jersey, Pennsylvania, Virginia, West Virginia, and Washington, D.C., with estimates of atmospheric zinc emissions and other materials
Describes zinc smelting processes used in the mid-Atlantic states, including locations and photographs of the plants, along with statistics and discussion of environmental issues.
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.
National Geochemical Database: Rock
Geochemical analysis of rock samples collected and analyzed by the USGS. This dataset includes and supersedes rock data formerly released as "Geochemistry of igneous rocks in the US extracted from the PLUTO database"
National geochemical survey database
National-scale geochemical analysis of stream sediments and soils in the US, from existing data, reanalysis of existing samples, and new sampling. Goal for sample density is one per 289 square km.
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.
