Cleaning groundwater at ex-AFB

MOBILE, Ala. - U.S. Army Corps of Engineers' Savannah, Ga., District is providing remedial action at the former Brookley Air Force Base in Mobile County. Delmonico-PKS JV, LLC, has been contracted to perform area clean up as part of the Formerly Used Defense Sites (FUDS) Program. DoD is responsible for the environmental cleanup of properties formerly possessed by the United States and under the jurisdiction of the Secretary of Defense prior to October 1986. The Army is the DoD’s lead agent for FUDS. As part of the clean-up process, barrels of materials - sodium Bicarbonate to adjust the pH of groundwater and Emulsified Lecithin Substrate, a food grade carbon that enhances the bioremediation. It basically creates an anerobic environment in the subsurface that allows bacteria to work on the contamination and degrade it. Once the process is complete, the contractor will remove some contaminated soil. In its place, the contractor will replace that soil with clean soil. The action is anticipated to be completed by the end of October.

Some of the former base is also the site of an Airbus commercial aircraft production facility.
