This case involved gasoline (BTEX and MTBE) impact to soil beneath the site and groundwater beneath and off site. Site assessment was accomplished with a network of 12 groundwater monitoring wells distributed across the site, in city streets and on neighboring properties. The site was also located very near the City of Tustin drinking water wells. The gasoline plume extended 80 feet to groundwater. Remediation was accomplished with the installation and operation of soil vapor extraction and groundwater pump and treat systems. Due to the predominately sandy soil matrix at the site, the soil and groundwater cleanup was accomplished with a system of four soil vapor extraction wells and three pumping wells. Active remediation of the 80 foot deep soil plume and groundwater contamination was accomplished in four years. Closure was received from the Orange County Health Care Agency.
