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 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
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
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
