Released under Phase II of the Oak Ridge Health Studies Agreement. Bear Creek Valley is located west of the Y-12 Plant, and some of the burial grounds for the plant are located in the valley. One of the burial grounds is called Burial Ground A, and the trenches previously received solid wastes generated by the plant. However, most of the trenches were closed in the 1960's and some waste oils and other liquids were injected into the closed trenches. At some time in the past, some polychlorinated biphenyls (PCBs) were added to one or more of the trenches. In the early 1970's, oil wastes were observed to be leaking from one or more of the filled trenches and entering 2 drainage ditches which exited into Bear Creek. Small holding ponds, called Pond No. 1 and Pond No. 2, were built to trap floating oil from these seeps. During the late 1970's, analysis of the sediment on the bottom of the ponds as well as the floating oily waste on top of the ponds showed the presence of polychlorinated biphenyls (PCBs). In the 1980's, close out plans were prepared to drain the water from the ponds, remove the PCB contaminated sediment, and install a collection system for any seeps coming from the old trenches. This report discusses the laboratory and pilot plant studies related to the treatment of the water in the ponds.
