The organic contaminants that are most commonly detected in groundwater are low-molecular-weight, chlorinated aliphatic hydrocarbons such as trichloroethylene (TCE), tetrachloroethylene (PCE), 1,1,1-trichloroethane, carbon tetrachloride, and chloroform. The authors exposed unsaturated soil to natural gas to enrich for methanotrophs and for organisms that oxidized the other small alkanes present in natural gas and then examined the soil for the capacity to remove TCE from infiltrating water. As a control, the behavior of TCE in soil exposed to natural gas was compared to that of TCE in an earlier study (10), in which the same soil in the same experimental configuration was dosed with a solution of TCE but was not exposed to natural gas.
