It uses low-volume air sparge and chemical addition to maintain optimum aquifier conditions for native bacteria/archaea reduction/conversion of contaminants. PHOSter was developed in 1995 by the Department of Energy for reduction of trichloroethylene (TCE) in the Savannah River Plant and it is commercialized by Freeman and Vaughn.
