Abstract:

Through two decades of laboratory and field research, it has been generally believed that cis 1,2 dichloroethene cDCE and vinyl chloride VC can further degrade through a variety of mechanisms, including i anaerobic reductive dechlorination to ethene andor ethane ii anaerobic oxidation to carbon dioxide CO2 under iron- andor manganese-reducing conditions iii aerobic oxidation and co-oxidation to CO2 and iv reduction through a variety of metal and metal-oxide surface-catalyzed reactions. Knowledge of the various cDCE and VC degradation processes has led to the development and deployment of monitored natural attenuation MNA and enhanced in situ bioremediation EISB remedies at a significant number of Department of Defense DoD sites impacted by chlorinated solvents.
