Trichloroethylene (TCE) is the most frequently observed volatile organic contaminant at RCRA sites and in ground water. In situ aerobic bioremediation of aquifers contaminated with TCE, c-DCE, T-DCE, and vinyl chloride, is a potential means of restoring the aquifers. This study looks at field in situ data on chlorinated aliphatic hydrocarbon (CAH) transformation by indigenous microorganisms with a substrate other than methane in order to obtain a comparative evaluation of the effectiveness of different substrates for CAH transformation. Phenol was used for this study. The results indicate that with rapidly growing aerobic bacteria it is difficult to develop and maintain a uniform population in situ; however, bioremediation using micoorganisms grown on phenol is a possibility. 29 refs., 8 figs., 5 tabs.
