Historical uses of Chlorinated solvents as well as other widely used dense non-aqueous phase liquids (DNAPLs) pose serious
long-term groundwater contamination problems in the United States and in other industrialized countries.
The U.S. Department of Energy (DOE), the National Aeronautics and Space Administration (NASA), the U.S. Environmental Protection
Agency (EPA), the U.S. Department of Defense (DOD), U.S. Navy (NAVFAC) and the U.S. Air Force have formed the Interagency DNAPL
Consortium (IDC) in order to conduct comparative demonstrations of DNAPL remediation technologies Since its inception, CBTR
has served to provide technical support to the IDC and field engineering management to the technology demonstrations conducted at
Launch Complex 34.
The IDC has selected three promising DNAPL remediation technologies for a comprehensive evaluation at Launch Complex 34 (LC34)
at Cape Canaveral, Florida. LC34 is the site of the tragic Apollo 1 fire which occurred in 1967. Its use as a launch facility
and rocket motor cleaning site resulted in subsurface DNAPL contamination involving chlorinated cleaning agents. Col. John
Koutsandreas of the CBTR, Mr. Skip Chamberlain of the DOE and Dr. Tom Early of Oak Ridge National Laboratory provide technical
support and supervision, and assist in the management of this technology demonstration project.
The three technologies selected for evaluation are chemical oxidation with potassium permanganate, Six Phase HeatingTM and Steam
with Co-Air injection. To date, the oxidation and Six Phase Heating technologies have been deployed and cost and performance
reporting are being prepared. The third technology is currently in operation with an expected completion later this year.
It is anticipated that all reporting will be completed by March of 2002.
