Table 4 In Situ Flushing - Recovered Contaminant Mass / Economic Information Available Total Number of Case Studies = 84 GWRTAC Project Reported Contaminant Reported Fraction of Economic Scale of ID Name Mass Recovered Inital Mass Recovered Information Project FLSH0038 Sindelfingen, Germany Within 18 Months After TCE Spill, 17 Metric Tons of Chlorinated Hydrocarbons were Recovered FLSH0074 SW Tank Farm, Tinker Air Force Base, OK FLSH0041 Texas Eastern Transmission Facility, Delmont, PA FLSH0042 Thouin Sand Quarry, Quebec, CA FLSH0053 U.S. Air Force Plant 4, Fort Worth, TX Initial Mass Estimates not Available from Source Full- Scale/Commercial Pilot/Field Demonstration 0.32 Kg PCBs Unknown At present, no plans exist for further Pilot/Field surfactant flushing at the site. Instead, recovery and treatment of PCBs at the spring is planned. The limiting factor controlling the duration of the surfactant injections presented above was the ability to effect Demonstration 992 Kg DNAPL 86% Residual DNAPL Pilot/Field Demonstration Project is in Progress; Surfactants may or may not be Applicable FLSH0051 U.S. Coast Guard, Traverse City, 3.354 gm PCE Total, 2.757 gm PCE Through MI Surfactant-Enhanced Solubilization FLSH0054 U.S. DOE Gaseous Diffusion Plnt, Paducah, KY FLSH0075 U.S. DOE Paducah Gaseous Diffusion Plant FLSH0008 U.S. DOE Portsmouth Gaseous Diffusion Site, Piketon, OH FLSH0043 Umatilla Army Depot (Lagoons), Hermiston, OR FLSH0044 United Chrome Products, Corvallis, OR FLSH0083 University of Arizona - HC Solubilzation and Mobilization by Biosurfactant FLSH0082 University of Florida - Two- Dimensional Flow Experiments and Simulations FLSH0081 University of Illinois - Impact of Surfactant of Configuration of HC Lens No Increase in TCE Concentration was Achieved 20 to 40 L (Approximately 5.to 10 Gallons) DNAPL Project is in Progress; Surfactants may or may not be Applicable Pilot/Field Demonstration Intial Mass not Known Pilot/Field Demonstration No Increase in TCE Concentration was Achieved Pilot/Field Demonstration Laboratory/Bench Scale Approximately 50% of Original DNAPL No estimated full-scale cost was available. Pilot/Field Demonstration Project is in Progress Project is in Progress Full- Scale/Commercial Project is in Progress; Over 3 Years, 9.7 MM Gallons of Impacted Groundwater Containing 26,732 lbs. of Cr+6 have been Removed Project is in Progress Cost estimates indicate that treatment costs Pilot/Field were estimated at $40/lb of Cr+6 removed for Demonstration the first 25,000 lbs. As Cr+6 concentrations drop in later phases of operation, it is estimated that costs will double to $80/lb of Cr+6 removed. 58% of Residual NAPL (Hexadecane) Removed Within Three Pore Volumes From Laboratory Sand Columns Laboratory/Bench Scale Laboratory/Bench Scale Laboratory/Bench Scale FLSH0052 University of Michigan Project is in Progress Project is in Progress Laboratory/Bench Scale Ground-Water Remediation Technologies Analysis Center Operated by CTC 1-800-373-1973 Page 24 GWRTAC 1998 As of 11/17/98
