Thermal desorption cleans up PCB sites

Polychlorinated biphenyls (PCBs) used as insulating and cooling oils in transformers and large electric motors may have contaminated areas where these equipments were manufactured, stored, serviced and disassembled. Remediation of these sites is done by electric in situ thermal desorption technology using thermal blankets and/or thermal wells. By destroying the contaminants in place, the continued liability of moving hazardous waste from one location to another is eliminated. This approach is highly effective and economical for difficult contamination problems resulting from a wide range of organic pollutants, and much less intrusive, with lower impacts on the surrounding community.
