The focus of this work was to evaluate the potential of aerobic microorganisms, grown on butane propylene, and propane, to cometabolically degrade chlorinated aliphatic hydrocarbons (CAHs). The key contaminant of concern was trichloroethylene (TCE). However, other CABs of interest were chloroform (CF), 1,1,1-trichloroethane (TCA), 1,1-dichloroethylene (1,1-DCE). The study focused on microbes stimulated from the subsurface core materials from Air Force Base (AFB) sites with subsurface CAB contamination. Comparisons were also made with other gaseous substrates such as methane, propylene, and ammonia that have shown activity for TCE cometabolism. Through microcosm and soil column studies the work determined the potential for applying these processes for in-situ remediation of CAB contamination at AFB sites.
