One of the most difficult sites that environmental professionals must deal with are sites which are contaminated with chlorinated solvents. Chlorinated solvents were compounds that worked extremely well in many industrial and commercial operations. Two of the prime uses of chlorinated solvents were Tetrachloroethene (PCE) used most commonly as a dry-cleaning solvent and Trichloroethene (TCE), used in a plethora of commercial operations ranging from industrial vapor degreasers to spray cleaner in local gasoline stations, to waterproofing shoe sprays.
Remediation may also be complex and may involve several phases rather than the selection of a sole methodology. Successful remediation will depend on effective delineation of the source or sources, the physio-chemical composition of the soil or water and the biological effectiveness of degradation, if any.
This course is designed to familiarize attendees with the various problems caused by chlorinated solvents: the difficulties encountered in attempting to delineate contaminated soil and water; and the process by which one may select a method or methods to successfully remediate chlorinated solvent contaminated sites.
