Cost and Performance Report - Use of Cometabolic Air Sparging to Remediate Chloroethene-Contaminated Groundwater Aquifers
Abstract
The Environmental Security Technology Certification Program (ESTCP) supported an 18-month field study to investigate the cometabolic air sparging (CAS) process at the McClellan National Test Site, California. The purpose of the demonstration was to evaluate the effectiveness of and costs associated with CAS for removal of chlorinated aromatic hydrocarbons (CAHs) from groundwater. Specific project objectives were: Evaluate subsurface oxygen and growth substrate (i.e. propane) distributions Determine growth substrate acclimation requirements; Determine growth substrate and oxygen uptake rates, after acclimation; Evaluate the ability of indigenous bacteria to degrade different CAH compounds; Predict long-term process stability Estimate CAS costs and compare costs with the cost of traditional air sparging or pump and treat technologies. This report describes the cost and performance aspects of the effort.
