Temporal geochemistry data from five springs in the Cement Creek watershed, San Juan County, Colorado

Seasonal geochemical data intended to understand formation of ferricretes and to help understand the ground-water flow system.

Info
Geochemical data from analyses of rock, sediment, water, and solid-phase leaching at the Tuba City open dump, Tuba City, Arizona

Study of sources and resulting transport of radionuclides and other dissolved constituents in the surrounding ground water.

Info
Geochemical analyses of rock, sediment, and water from the region in and around the Tuba City landfill, Tuba City, Arizona

Regional samples of rock, sediment, leachates, and water were collected in and around the TCL site and analyzed for major and minor elements and radionuclides

Info
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.

Info
Water and rock geochemistry, geologic cross sections, geochemical modeling, and groundwater flow modeling for identifying the source of groundwater to Montezuma Well, a natural spring in central Arizona

This report releases data, cross section, and model information related to the identification of travel paths for groundwater supply and principal stratigraphic and structural features that serve as constraints or conduits for groundwater movement.

Info
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.

Info
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.

Info
Solid-phase data from cores at the proposed Dewey Burdock uranium in-situ recovery mine, near Edgemont, South Dakota

Geochemical and mineralogical analysis of uranium-bearing sandstone in order to help understand mineral deposits of this type.

Info
Whole rock geochemistry and grain-size analyses from sediment and rock near Tuba City Open Dump, Tuba City, Arizona

Chemical analysis of geological materials at this EPA Superfund site located on lands of the Hopi and Navajo nations, which may contain mine waste.
