A Navy contractor will be cleaning up groundwater in part of the future Town Center area next to the Seaplane Lagoon by injecting a solution of cheese whey, emulsified vegetable oil and water into nearly 200 wells that go down between 30 and 40 feet. The whey and vegetable oil will cause natural bacteria to flourish that will feed on the toxic trichloroethene (TCE) solvent causing it to break down.
The goal of the cleanup is to minimize the potential for hazardous vapors entering buildings, and chemicals migrating into the Seaplane Lagoon. TCE is an industrial solvent used to degrease metal parts. It was heavily used at aircraft and ship engine repair facilities on the site. A leak from a rail car is believed to be one of the major sources of the plume.
