Remediation of Uranium-Impacted Sediments in a Watercourse

摘要

In 2009, remediation began for a nonoperational fuel-cycle facility previously used for government contract work. Between 2009 and spring of 2011, the work consisted of remediating several areas of uranium-impacted soil, decontamination and demolition of two impacted building structures (including the slab and underlying process piping and utilities), and removing more than 1100 meters of buried waste line piping. Late in the spring of 2011, the last phase of remediation commenced: removal and offsite disposal of uranium-impacted sediments from portions of an approximately 1200-m-long gaining stream known as the "Site Brook." In November 2011, the remediation and restoration of Site Brook was comolete.
