Abstract
Over the past two years, EPA Regional staff have made observations at several field sites that suggested an inexpensive alternative treatment for PCBs using quicklime containing materials. As a consequence of these observations, EPA entered into a cooperative agreement with RMC Environmental and Analytical Laboratories. However, the small project did not include all the experiments needed to prove chemical decomposition of PCBs as the major effect of quicklime treatment. An in-house project was designed to answer questions about quicklime treatment of PCBs. Synthetic soil samples were spiked with three PCB congeners (3.5-dichlorobiphenyl, 3,3;5,5'-tetrachlorobiphenyl, and 2,2;4,4;5,5;-hexochlorobiphenyl) and treatment with quicklime and water. PCB losses (60% to 85%) were evidenced after five hours of treatment. However evaporation and steam stripping at elevated temperature conditions, rather than PCB decomposition, accounted for most of the losses observed. The amounts of observed dechlorination products were not dependent on the duration of lime treatment and no evidence of phenyl-phenyl bond cleavage was found. The use of quicklime as an in-situ treatment of removal of PCBs is not supported by these results.
