Methanotrophic Cometabolic Transformation of Vinyl Chloride and Other Chlorinated Ethenes In Aquifer Microcosms

摘要

In situ cometabolic biotransformation of organic groundwater contaminants as a means of site remediation is a subject of increasing interest to the scientific community. Traditional pump-and-treat methods for remediation often require long treatment times with much energy spent in removing the contaminants from the subsurface. Using the contaminated subsurface as a biological reactor is one potential advantage of in situ remediation schemes. Unlike above-ground reactors where reaction conditions can be carefully controlled, subsurface treatment requires that reaction conditions conform to an existing and sometimes limiting set of environmental conditions. Site specific investigation of the potential for in situ treatment and the ability to influence the desired biological reaction conditions in the subsurface environment are important considerations to any in situ treatment scheme.
