The goal of the project was to evaluate the technical and cost performances of in situ chemical oxidation (ISCO) technology for remediation of dense nonaqueous phase liquid (DNAPL) source zones. The chlorinated volatile organic compound trichloroethylene was present in the aquifer as a DNAPL source at Launch Complex 34. Smaller amounts of dissolved cis-1,2-dichloroethylene and vinyl chloride were present in the ground water. The field demonstration of ISCO technology started at Launch Complex 34 in September 1999 and ended in April 2000. Performance assessment activities were conducted before, during, and after the field demonstration.
