Demonstration of Biodegradation of DNAPL through Biostimulation and Bioaugmentation at Launch Complex 34 in Cape Canaveral Air Force Station, Florida Innovative Technology Evaluation Report September 2004

This report presents results from the project field demonstration of a biostimulation and bioaugmentation technology for treatment of a dense, nonaqueous-phase liquid (DNAPL) source zone at Launch Complex 34, Cape Canaveral Air Force Station, FL.

The goal of the project was to evaluate the technical and cost performance of the biostimulation and bioaugmentation technology when applied to a DNAPL source zone. The chlorinated volatile organic compound (CVOC) trichloroethylene (TCE) is present as a DNAPL source in the aquifer at Launch Complex 34. Smaller amounts of dissolved cis-1,2-dichloroethylene (cis-1,2DCE) and vinyl chloride (VC) also are present in the groundwater as a result of the natural degradation of TCE.

The field application of the treatment technology began at Launch Complex 34 in June 2002 and ended in February 2003. Performance assessment activities were conducted before, during, and after the field application.
