The 618-10 Burial Ground was in operation from 1954 to 1963 and consists of 94 vertical pipe disposal units (VPUs) and 12 solid waste disposal trenches. Remediation of the trenches began in March of 2011 under the River Corridor Closure Contract (RCCC)a. This work was considered to be high risk because the trenches are known to contain a large radiological inventory and have the potential to release airborne contaminants. Remediation is being performed without a containment structure by using a combination of engineering controls and monitoring equipment. The engineering controls include storing material below grade using a surge trench, the application of soil fixatives, and applying material storage limits. The use of radiological and chemical monitoring equipment is also used to provide near real-time information to guide remediation activities and limit contact of waste until risks can be evaluated. Remediation of the trenches is progressing without any significant personnel or environmental issues. (authors)
