Extraction of degradation rate constants from the St. Joseph, Michigan trichloroethene site

Technical Report ·
OSTI ID:422177

Anaerobic biodegradation of TCE occurs through successive dechlorination from trichloroethene to dichloroethene, vinyl chlorine and ethene. The process produces three isomers of DCE (1,1-DCE, cis-1,2-DCE, and trans-1,2-DCE). Although TCE was commonly used in industry, the DCEs were not; and ethene would not be expected in most ground waters. Thus the presence of these compounds are indicative of degradation when found in anaerobic ground waters. Degradation of TCE was established from the field data. The purpose of this paper is to present estimates of averaged concentrations, mass flux and degradation rate constants.
