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.
The mass of compounds released to the environment in this state cannot be calculable given the multitude of uses and users. Chlorinated compounds can cause a multitude of problems: they can cause vapor intrusion issues; they can solubilize in water; they can form Dense Non-Aqueous Phase Liquids. After "remediation", they may rebound based on the soil physical chemistry encountered. Because of their common use, it is not uncommon to find "mixed plumes" which have more than one contributor and, possibly, more than one chlorinated compound. Some chlorinated solvents have natural degradation pathways, which degradation rates are also a function of the bulk chemistry of the soil. From a forensic point of view, there are some simple ways to identify one source from another. In some cases, identifying sources will require sophisticated chemical techniques such as isotopic analysis.
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.
While this course is designed primarily for LSRPs, the information regarding chlorinated solvents will inform those who are in any way involved with sites contaminated with these compounds. Individuals such as attorneys, corporate environmental personnel, etc. will be informed about the investigation and remediation of chlorinated solvent contaminated sites. A heavy emphasis will be placed on PCE, TCE and TCA, the most commonly encountered chlorinated solvents.
Mr. Abrams, Vice President & Director of Remediation Technology, Langan Engineering & Environmental Services has over 35 years of experience in site remediation, soil and groundwater remediation, water treatment, Brownfields redevelopment, and engineering design. He is an expert in remedial technology, with particular emphasis on bioremediation, chemical oxidation/reduction technologies, soil vapor extraction, and air sparging. He has recently become involved in the emerging fields of emerging contaminants and sustainable remediation.
