The main focus of this Limited Scope SERDP project was to determine the extent to which methanotrophs may contribute to the biodegradation of chlorinated volatile organic compounds cVOCs in low pH groundwater aquifers. Our objectives included 1 determining whether methanotrophs exist in acidic groundwater aquifers and are capable of degrading methane and cVOCs, with a specific focus on trichloroethene TCE and 2 to identity of the key methanotrophs andor methane-oxidizing genes present in acidic groundwater systems using advanced molecular techniques, including stable isotopeprobing SIP. The role of methanotrophs in biodegrading cVOCs in low pH groundwater has received little study as has the potential to enhance their activity with methane or other amendments.
