This project in Riverside, California, involved an insurance company policy that was called into effect. The insurance company, American International Group (AIG), paid for the client’s attorney, paid for third party oversight of The Reynolds Group’s work, and was in-line to provide funding to the project over a certain limit.
According to the Santa Ana Regional Water Quality Control Board’s (SARWQCB) Ken Williams, TRG removed more gasoline from the ground at this site than at all but two other cases he had worked on. Site assessment was accomplished with a network of 17 groundwater monitoring wells spread over an area 800 feet by 300 feet. The gasoline plume extended 100 feet to groundwater. Up to eight feet of free phase gasoline was discovered floating on the groundwater beneath the site. Remediation was accomplished with the installation and operation of free product recovery, soil vapor extraction and air sparge systems. Closure was obtained by working closely with the SARWQCB, understanding the detailed subsurface conditions, applying the most applicable remedial technology to the case, and operating it efficiently.
