Aerobic bioreactors for the removal of chlorinated solvents in groundwaters are a promising alternative to conventional treatment methods. Biodegradation is advantageous because in one step the contaminants are destroyed in addition to being removed from the treated waters. Chloroform, 1,2-dichloroethane, and trichloroethylene (TCE), for example, are degraded at concentrations of 1 to 1000 mu g/L by certain heterotrophic bacteria, yielding innocuous end products. The nonspecific oxygenase enzymes of the bacteria enable the cometabolism of the chlorinated solvents.
