Demonstration of In Situ Dehalogenation of DNAPL through Injection of Emulsified Zero-Valent Iron at Launch Complex 34 in Cape Canaveral Air Force Station, Florida Innovative Technology Evaluation Report
This report presents the project field demonstration of emulsified zero-valent iron (EZVI) 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 nanoscale EZVI 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 cis1,2-dichloroethylene (cis-1,2-DCE) and vinyl chloride (VC) also are present in the groundwater as a result of the natural degradation of TCE.
The field application of EZVI technology began at Launch Complex 34 in June 2002 and ended in January 2003. Performance assessment activities were conducted before, during, and after the field application.
