KETTLEMAN LANE <br /> LODI, CA <br /> San Joaquin County Environmental Health Department (EHD) has reviewed the reports G <br /> of the groundwater samples collected from the monitoring wells at this site since January <br /> 2000 (11 sampling events) and the analytical results of the soil samples collected <br /> beneath the underground storage tanks (USTs), product lines, and dispensers that were <br /> removed in October 2002. <br /> Some contamination was found in soil samples from beneath the USTs, product lines, <br /> and dispensers in both the June 1999 and October 2002 UST system removals. <br /> Groundwater sample results have been non detect to detections of low levels of <br /> contaminants. Verbal requests for closure of this site have been made to EHD. A report <br /> requesting and justifying closure of this site must be prepared and signed by an <br /> appropriately licensed individual in the State of California. After EHD has concurred that <br /> site closure is justified, the existing on site wells (6 monitoring wells, groundwater <br /> extraction well and 8 vapor extraction wells) must be destroyed under permit and <br /> inspection of EHD. <br /> If you have any questions contact me at (209)468-3449.' <br /> Donna Heran, RENS, Director <br /> Environmental Health Department <br /> Margaret Lagorio, Supervising REHS <br /> Site Mitigation Unit <br /> l <br /> c: URS Corp—Vernon Elarth ! <br /> Mark & Deanne Garibaldi, 407 W.
