Title: In situ groundwater remediation using air sparging, vapor extraction and bioventing

Over 60 years of refining operations have resulted in petroleum hydrocarbon contamination of soil and groundwater at the 74-acre former Golden Eagle Refinery in Carson, California. Successful negotiations with the California Regional Water Quality Control Board (RWQCB)-Los Angeles Region, and the California Department of Toxic Substances Control (DTSC) resulted in the use of a phased approach, separating the soil and groundwater remediation activities. Based on the findings of site assessments conducted to define and characterize the soil and groundwater contamination at the site, remediation of the soil was initiated first. By obtaining agency approval on the soil cleanup, the site could proceed with development during the groundwater remediation activities. Prior to groundwater remediation, an air sparging pilot test was performed at the site on a highly heterogeneous site consisting of mostly low permeability soils in southern California. This paper how the pilot test was performed, the test results and the accuracy of the results when scaled up to the full operating system.
