A feasibility study of utilizing indigenous bacteria that use methane as a source of cell carbon and energy (methanotrophs) for in-situ bioremediation of groundwater contaminants at the St. Joseph site is summarized. The contaminants, compounds, can be biotransformed by methanotrophic bacteria, which are found in some locations of the site in adequate populations. The process involves stimulating the growth of native populations of methanotrophs by injecting water containing dissolved methane and oxygen into the aquifer. The stimulated population of methanotrophs in turn has the capability to degrade trichloroethylene, 1,2-cis-dichloroethylene, 1,2-trans-dichloroethylene, and vinyl chloride.
