B&W has targeted the two source areas within the “A” plume for in situ enhanced anaerobic bioremediation (EAB). The two areas are the Source Target Area (STA) and the Boundary Target Area (BTA). A field pilot test of the EAB was initiated at the STA in October 2011, with injection of amendment s into five wells in the weathered bedrock. The carbon substrate being used is sodium lactate, which is soluble, fast acting substrate, and utilized over a period of one year or less. The results of this pilot test will be submitted in a separate report.
B&W submitted a work plan for enhanced anaerobic bioremediation in the Boundary Target Area in August 2012. The EAB pilot test will be conducted by injecting a carbon source (emulsified vegetable oil) and a mixed microbial consortium that includes halorespiring bacteria to promote the reductive dechlorination of chlorinated ethenes present in groundwater. The carbon substrate and bacterial culture will be injected into shallow groundwater using direct-push technology. Field work will begin in the Fall of 2012.
The Babcock &Wilcox Nuclear Operations Group (Mt. Athos site) is located near Lynchburg, Virginia on a 560-acre site adjacent to the James River in the northeast corner of Campbell County.
The complete list of contaminants of concern identified in the RFI include TCE, PCE, bromoform, chloroform, methylene chloride, cis-1,2-dichloroethylene, trans-1, 2-dichloroethylene, trichlorofluoromethane, and vinyl chloride. No immediate threats to human health or the environment have been identified.
