This can be compared with the original USAF estimate for cleanup of the DNAPL that used the traditional time frame of 30 years with a cost o Demonstration Approximately 350 L (92 Gallons) NAPL >85% Cell-Wide Basis, >95% in Central Flood Zone, >75% in Bottom 0.5 m Pilot/Field Demonstration Project not yet Begun Project not yet Begun Full- Scale/Commercial Project is in Progress Project is in Progress Laboratory/Bench Scale FLSH0025 JADCO-Hughes, Belmont, NC Project not yet Begun Project not yet Begun Pilot/Field Demonstration FLSH0001 Koppers Co. Inc., Seaboard Plant, Kearny, NJ FLSH0026 Laramie, WY, Private wood treating site Project is in Progress; During First 3 Months of Operation, Over 11,000 Gallons DNAPL Collected 1,900 Gallons PAH-Contaminated Oil Removed from 27x27' Test Cell; 23,600 Gallons Oil were Produced from 130x130' Test Cell FLSH0027 Lee Chemical, Liberty, MO Project is in Progress; Performance Results not yet Available FLSH0028 Lipari Landfill, Pitman, NJ Project is in Progress; Performance Results not yet Available Ground-Water Remediation Technologies Analysis Center Operated by CTC 1-800-373-1973 Page 22 Project is in Progress Pilot/Field Demonstration 94% Reduction in Oil Concentration (27x27' Test Cell) Project is in Progress; Performance Results not yet Available Project is in Progress; Performance Results not yet Available Full-scale applications of the chemically enhanced recovery technique would require an extensive piping network and large amounts of fluids and chemicals. Based on extrapolation from the 1989 pilot test, fullscale in situ soil flushing would require more Pilot/Field Demonstration Full- Scale/Commercial Full- Scale/Commercial GWRTAC 1998 As of 11/17/98
