Assessing UST corrective action technologies: Lessons learned about in situ air sparging at the Denison Avenue Site, Cleveland, Ohio. Project report
In situ air sparging (IAS) has been used at an increasing number of sites to address groundwater contamination. Because of the lack of substantive performance data, however, the actual effectiveness of the system is not known. The EPA Office of Research and Development Risk reduction Engineering Laboratory (ORD RREL) with the EPA Region 5 Office of Underground Storage Tanks, the Ohio State Fire Marshal, and BP Exploration & Oil, Inc. (BP) participated in a field evaluation of an IAS system at a petroleum leaking UST site in Cleveland, Ohio. The purpose of the study was to provide performance data that will be independently evaluated by EPA to better understand IAS effectiveness. The report presents the site and monitoring data provided by BP over a 2-year period. The chemical data indicated an overall decrease of BTEX concentrations in groundwater to nondetectable levels shortly after startup of the IAS system. Variability in the chemical and process data also precludes making any definitive link between the decrease in contaminant concentrations and IAS performance at this site.
