摘要

Reductive dechlorination occurs frequently in large trichloroethylene (TCE)plumes. TCE is transformed largely to cis-dichloroethylene (cis-DCE), then to vinyl chloride, and finally to compounds that do not contain organic chlorine. This abstract evaluates the rate and extent of natural reductive dechlorination of TCE in two large plumes with similar properties. The half life for attenuation of TCE and its dechlorination products was approximately six months in both plumes. The rates of attenuation in the two plumes are slow as humans experience time. In particular, they are slow compared to the time usually devoted to site characterization. However, in plumes with a long residence time, on the order of decades, they have significance for protection of waters that receive the plumes.
