The paper presents an EPA evaluation of the first field demonstration of an in situ stabilization/solidification process for contaminated soil under the EPA Superfund Innovative Technology Evaluation (SITE) program. Demonstration of the process was a joint effort of two vendors: International Waste Technologies' (IWT) of Wichita, Kansas, who provided the treatment process, specifically the proprietary additive called HWT-20, and Geo-Con, Inc., of Pittsburgh, Pennsylvania, who provided both engineering and hardware for the in situ soil treatment. The field demonstration took place in April, 1988 at a site contaminated mainly with polychlorinated biphenyls (PCBs). EPA tested the soil before and after treatment and the EPA evaluation of the process is based on results from the testing. A year later, in April 1989, EPA tested again the treated soil and results of that testing were compared to those of the demonstration. Results of the EPA evaluation of the IWT process, the Geo-Con performance, and treatment costs are discussed separately. (Copyright (c) 1990--Air & Waste Management Association.)
