Characterization Of Dnapls At The Cape Canaveral Interagency Project

National Aeronautical Space Administration, Environmental Protection Agency and U.S.<br>Air Force, is sponsoring a project at Cape Canaveral, Florida to test subsurface<br>characterization and remediation technologies. Upon completion of the project we will<br>publish cost and performance data gleaned from these subsurface demonstrations. The<br>characterization program utilized various types of tools to define the area of<br>contamination and to determine the volume of contamination in the subsurface. Predemonstration<br>sampling, monitoring and analysis of soil and groundwater samples was<br>performed from June 1999 to August 1999, in three test plots located at Launch Complex<br>34 (LC34), Cape Canaveral, FL. Initial evaluations indicate the site contains 17,000 kg of<br>trichloroethylene (TCE) from the Apollo space program. Three remediation technologies<br>were selected to perform side by side demonstration in-situ oxidation, steam stripping<br>and Six-Phase HeatingrM (SPH). Vendors with geophysical tools are requesting to use the<br>Cape Canaveral site to test their characterization technologies and compare the results to<br>the intrusive techniques that were utilized. The tools are being tested for contaminant<br>location and to extend the understanding of DNAPL movement in the subsurface for<br>future federal and private sites.
