Air Sparging and Soil Vapor Extraction at Landfill 4, Fort Lewis, Washington: Cost & Performance Report
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.
Assessing UST Corrective Action Technologies: Lessons Learned about In Situ Air Sparging at the Denison Avenue Site, Cleveland, OH
In 1996, EG&G Technical Services of West Virginia (TSWV) Inc. successfully demonstrated the effectiveness of combined air sparge and biostimulation technology to remediate benzene contamination at a former underground coal gasification (UCG) test site in northeastern Wyoming. Benzene concentration reductions greater than 80% were observed two months after demonstration operations were suspended. Available through the DOE Information Bridge.
A Field-Scale Demonstration of Air Sparging to Remediate Tritiated Fluids Two pilot field-scale studies were conducted in 1996 to evaluate the potential of air sparging to remediate tritiated fluids. The results of the two experiments demonstrated that air sparging of tritium is a viable process in the field.
In Situ Air Stripping of Contaminated Groundwater at the U.S. Department of Energy's Savannah River Site, A/M Area, Aiken, South Carolina: Cost & 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.
Describes the results of 10 air sparging demonstrations completed at DoD facilities to implement and evaluate the Air Sparging Design Paradigm.
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.
Design, performance, and cost summary data were collected from nine packed-tower and low-profile air stripper treatment systems that address MTBE contamination in ground-water supplies in the 1990s to develop a series of cost and reliability curves and assess the accuracy of two models designed to predict the cost and performance of packed-tower and low-profile air strippers. Results indicate that a variety of different treatment train configurations can use air strippers successfully to remove a range of MTBE concentrations (i.e., from 10 to 2,400,000 ug/L). Removal efficiencies ranged from 65% to greater than 99.9%. The commercially available models predicted actual removal efficiencies within 15%.
This report summarizes field performance studies of the following source reduction technologies: air sparging, bioventing, biosparging, soil vapor extraction, multi-phase extraction, and excavation.
