Impact/Purpose:
The goal of this project was to evaluate the cost and performance of the steam Injection/extraction technology for remediation of DNAPL source zones.
Description:
The Interagency DNAPL Consortium (IDC) was formally established in 1999 by the U.S. Department of Energy, U.S. Environmental Protection Agency, the U.S. Department of Defense, and the National Aeronautics and Space Administration. The IDC performed five remediation techniques: steam injection, resistive heating, in situ chemical oxidation, bioremediation/biostimulation, and emulsified zero valent iron dehalogenation at a DNAPL location on Launch Compex 34, Cape Canaveral Air Station. This Innovative Technology Evaluation Report summarizes the results from the Dynamic Underground Stripping and Hydrous Pyrolysis/Oxidation steam injection pilot conducted from July to December 2001 at Cape Canaveral. In order to maintain hydraulic control and mitigate potential migration of DNAPL from the plot, the vendor, MSE Technology Applications, maintained a groundwater extraction rate of 22 gpm along the boundary of the steam injection pilot. The vendor extracted a total of 4,013,588 gals of water(equivalent to 11 pore volumes of the 75 ft x 50 ft test plot), including 372,473 gal of steam condensate. Linear interpolation of the TCE groundwater and soil concentrations indicated that 85% of the total (dissolved + DNAPL) mass was removed and 89% of the DNAPL mass was removed. The total cost of the steam injection application was $1,202,175. The site investigation for all five remediation technologies was $255.000.
