Elucidation of the Mechanisms and Environmental Relevance of cis-Dichloroethene and Vinyl Chloride Biodegradation

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 and/or ethane; ii) anaerobic oxidation to carbon dioxide (CO2) under iron- and/or 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.
