Removing gasoline from soil and groundwater through air sparging. Michael C. Marley. 2006; Remediation Journal - Wiley InterScience: "Although a soil vapor extraction system (SVES) had effectively remediated the vadose zone soils at a gasoline spill site in Pawtucket, Rhode Island, gasoline remained in the soils below the water table. The state Department of Environmental Management (DEM) closure criteria of 10,000 parts per billion (ppb) were still not met after five years. This article describes how an air sparging system was added to the effort for $57,000, and how after three weeks, closure criteria were achieved."
