Located on the border of Los Angeles and Culver City, this site lies within the Charnock sub-basin, from which the City of Santa Monica has historically obtained drinking water. The City’s production wells in the Charnock sub-basin were shut down in 1996 when MTBE was discovered to have impacted the deep aquifer. Due to its location within the Charnock sub-basin, strict scrutiny was applied to this site by the Los Angeles Regional Water Quality Board, the USEPA, and the City of Santa Monica. The gasoline released at this site had impacted the groundwater. The gasoline plume was assessed with a network of 15 groundwater monitoring wells. The remedial approach consisted of air sparging, soil vapor extraction, and injection of a chemical oxidant to “polish” the groundwater concentrations and achieve the stringent closure concentrations. Closure was granted by the Los Angeles Regional Water Quality Control Board. The Reynolds Group provided Cleanup Fund approved assessment and remediation services for this project.
