2/7/2012 - JOINT BASE LANGLEY-EUSTIS, Va. -- The Department of the Air Force, Joint Base Langley-Eustis, in corporation with the U.S. prepare its second five-year review of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) "Brown's Lake" (Site SI029) located at Fort Eustis.
In accordance with CERCLA, this review will evaluate the effectiveness and protectiveness of the Selected Remedy at Brown's Lake. Historic investigations found that lake sediment was impacted by polychlorinated biphenyls, poly-nuclear aromatic hydrocarbons, pesticides, base-neutral acid extractable compounds (BNAs), fuel hydrocarbons, and metals. The investigations led to an Interim Removal Action (IRA) in 1999 which involved draining and capping the lake bottom with clean fill. The post-IRA selected remedy for Brown's Lake included additional excavation of a drainage ditch, storm water control, multi-media long term monitoring, and institutional controls.
This review will also include a Site Status Summary of all data collected at 10 additional CERCLA sites (Sites AT006, CS030, CS036, LF001, LF002, LF004, TS037, TS038, TU032, and TU035) at Fort Eustis. The remedy has not been determined at these sites; therefore, the effectiveness cannot be evaluated at this time.
The report is anticipated to be finalized in November 2012.
