Biodegradation of N-nitrosodimethylamine in soil from a water reclamation facility
The potential introduction of N -nitrosodimethylamine (NDMA) into groundwater during water reclamation activities poses a significant risk to groundwater drinking supplies. Greater than 54% biodegradation of N -[methyl- 14 C]NDMA to 14 CO 2 or to 14 CO 2 and 14 CH 4 was observed in soil from a water reclamation facility under oxic or anoxic conditions, respectively. Likewise, biodegradation was significant in microcosms containing soil with no history of NDMA contamination. These results indicate that aerobic and anaerobic biodegradation of NDMA may be an effective component of NDMA attenuation in water reclamation facility soils.
