Water-Quality and Borehole Geophysical Data Associated with Uranium Background Concentrations at the Homestake Superfund Site near Milan, New Mexico: 2016 (ver. 1.2)

Metadata Updated: October 29, 2023

The datasets contained herein were collected as part of a cooperative U.S. Geological Survey (USGS) and U.S. Environmental Protection Agency (EPA) project entitled "Field Investigations to Help Support the Assessment of Background Concentrations for Uranium at the Homestake Mining Company, Superfund Site near Milan, New Mexico, July 2016." Groundwater samples were collected from pre-selected wells and analyzed for metals (including uranium), alkalinity, ammonia, common ions, nitrogen, gross alpha/beta, radium isotopes, Radon-22, uranium isotopes, stable isotopes, sulfur isotopes, nitrogen isotopes, helium-4, dissolved gases, tritium/helium-3, carbon-14 and chlorofluorocarbons. Groundwater samples were collected using micropurge, volumetric, and passive samplers. Seven different laboratories analyzed the samples; separate datasets containing the results from each laboratory are provided in this data release. Microsoft excel .xlsx, xml, and tab-delimited text files are included for most dataset. A subset of the files are in .csv format.
