【 摘 要 】

The U.S. Department of Energy (DOE) has requested that the Oak Ridge Institute for Science and Education (ORISE) conduct verification surveys of available grids at the David Witherspoon Incorporated 1630 Site (DWI 1630) in Knoxville, Tennessee. On March 6, 2008, an independent verification team (IVT) from ORISE conducted verification activities of the excavated areas in partial grids H19, J21, J22, X20, and X21. The DWI 1630 Site 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 DOEs decommissioning contractor, Bechtel Jacobs Company, LLC. (BJC), has performed characterization surveys, subsequent remediation, and verification surveys and sampling within the subject area. The areas have not been backfilled pending results from the Independent Verification (IV) survey.
