Abstract |
The David Witherspoon, Inc. 1630 Site (DWI 1630) received, processed, stored, and shipped scrap metal, including metal contaminated with radiological and chemical contaminants. Past site characterization activities identified numerous radiological and chemical contaminants, including uranium, thorium, heavy metals, polychlorinated biphenyls (PCBs), asbestos, and organic compounds. The contaminants have been noted in various media on the site, including debris, soil, sediment, groundwater, and surface water. There were no buildings located in the subject areas during site operations. The U.S. Department of Energys (DOE) decommissioning contractor, Bechtel Jacobs Company (BJC), LLC., has performed characterization surveys, subsequent remediation, and verification surveys and sampling within the subject area (BJC 2006 and ORISE 2007). DOE requested that the Oak Ridge Institute for Science and Education (ORISE) conduct verification surveys of available grids at the DWI 1630 in Knoxville, Tennessee. On May 29, 2008, a representative with the Independent Environmental Assessment and Verification (IEAV) team from ORISE conducted a verification survey of a partial area within Grid E9. |
