Air Sparging and Soil Vapor Extraction at Landfill 4, Fort Lewis, Washington: Cost & Performance Report
Air Sparging/ High Vacuum Extraction to Remove Chlorinated Solvents in Groundwater and Soil At the DOE Mound facility in Miamisburg, Ohio, an air sparging and high vacuum extraction system was installed as an alternative to a containment pump and treat system. Technical data are presented on the operating characteristics of the system. Available through the DOE Information Bridge.
Groundwater Pump and Treat and Soil Vapor Extraction at DOE's Lawrence Livermore National Laboratory, Site 300, GSA OU, Livermore, California: Cost and Performance Report
In Situ Enhanced Source Removal This report assesses the results of demonstrations of the following technologies: co-solvent solubilization, co-solvent mobilization, surfactant solubilization, surfactant mobilization, micro-emulsions, macromolecular complexation, steam injection, air sparging, and soil vapor extraction.
In laboratory studies and a field pilot-scale demonstration, Fenton's reagents were cycled through spent GAC to degrade sorbed chlorinated hydrocarbons taken up during the treatment phase of soil vapor extraction. Little carbon adsorption capacity was lost in the process.
JV Task 109: Risk Assessment and Feasibility of Remedial Alternatives for Coal Seam at Garrison, North Dakota The performance of SVE and multiphase extraction (MPE) for remediation of soil and ground water impacted by a hydrocarbon-contaminated coal seam was evaluated in Garrison, North Dakota, following the September 2005 release of an estimated 30,000 gallons of premium gasoline from an oil company facility. Free product was detected in cavities of the abandoned mine, as well as high concentrations of residual gasoline-based contaminants. SVE and MPE pilot tests confirmed high contaminant recovery efficiency at all three of the identified hot spots. The suggested remedial strategy is based on contaminant recovery and in situ degradation using a combination of thermally enhanced SVE in the source area, mobile MPE units transitioned to SVE in saturated impacted areas, and high-volume low-vacuum extraction from mining cavities based on a pioneering concept of controlled 'draft and channel' extraction technology.

Push-Pull Tests for Evaluating the Aerobic Cometabolism of Chlorinated Aliphatic Hydrocarbons: ESTCP Cost and Performance Report Single-well push/pull test methods were demonstrated at Fort Lewis Logistics Center (using toluene as a cometabolic growth substrate) and McClellan AFB (during cometabolic air sparging with propane as a growth substrate) to determine (1) the transport characteristics of nutrients, substrates, and CAHs and their transformation products; (2) the capability of indigenous microorganisms to utilize selected substrates and transform targeted contaminants and surrogate compounds; (3) the rates of substrate utilization and contaminant transformation; and (4) the combinations of injected nutrients and substrates that maximize rates of contaminant transformation.
The successful removal of VOCs (carbon tetrachloride, Freon 113, trichloroethene, and 1,1-dichloroethene) from the vadose zone during an SVE pilot test in 1998 led NASA to proceed with this alternative using a trailer-mounted unit that was moved among 4 locations from April 1998 until September 2005. The system achieved all of its specified performance objectives.
