In situ air sparging is a commonly used remediation technology which volatilizes and enhances aerobic biodegradation of contamination in Groundwater and saturated zone soil. Recently, some questions have been raised regarding the effectiveness of air sparging. To address these questions the results of 21 sparging case studies have been compiled to shed light on how well air sparging achieves permanent reduction in groundwater contaminant concentrations. The case studies included both chlorinated solvents and petroleum hydrocarbon contamination, and covered a wide range of soil conditions and sparge system parameters. In each case study, groundwater concentrations were compared before sparging was initiated, just before sparging was terminated, and in the months following shutdown of the sparging system.
