The U.S. Geological Survey (USGS) is the Nation's principal earth science agency, with major divisions focused on surface- and ground-water resources, geologic investigations, mapping, and biological resources. The recent USGS investigations cover microbial mobilization of radionuclides from uranium mill tailings (UMT); possible adverse impacts of abandoned mine land remediation strategies; development and field testing of in-situ remediation of uranium-contaminated ground waters; the comparative behaviors of uranium, thorium, and rare earth elements (REE) in acid mine drainage environments; and the use of U-234/U-238 isotopic ratio measurements to evaluate contamination of shallow ground water with uranium mill effluent.
