Analyses of 72 water samples include pH, conductivity, water temperature, major cation and anion concentrations, trace-element concentrations, and dissolved organic-carbon concentrations.
Chemical composition of sediments and soils are of interest because of the potential for human and wildlife health impacts from high metal contents due to over 100 years of mining activity.
In this area of historical lead-zinc mining activity, studies such as this help to assess the possibility of human exposure to cadmium and lead through eating fish.
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.
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.
Geochemical data for soils collected by USGS personnel and analyzed by the USGS. These data were originally entered into the Rock Analysis Storage System (RASS), a database that is now merged into the National Geochemistry Database.
National-scale geochemical analysis of stream sediments and soils in the US collected and analyzed under the National Uranium Resource Evaluation program.
