Hwy. 99 <br /> Stockton CA 95212 <br /> At the request of Mr. Lee Roy Pierce, the attorney representing Mr. Ray Baglietto and <br /> Mr. Frank Rauzi, a meeting was held to discuss the status of the above referenced <br /> contaminated underground storage tank (UST) site. Present at the meeting were Lee <br /> Pierce, Joe Baglietto and Frank Rauzi representing the responsible parties; John Lane <br /> and Greg Stahl, consultants to the responsible parties; James Barton, Regional Water <br /> Quality Control Board; and Margaret Lagorio, Nuel Henderson and Lori Duncan, San <br /> Joaquin County Environmental Health Department (SJCIEHD). <br /> Four main points of concern emerged from discussions at the meeting. <br /> 1. The soil vapor extraction system may have reached the point where it is no <br /> longer effective. Currently it is operated in a dual-phase mode to pull water <br /> from MW-4, but only when the groundwater extraction system is functioning. <br /> SJCIEHD stated confirmation soil borings should be installed to verify whether <br /> any soil contamination remains onsite. <br /> 2. The vertical extent of the groundwater contamination has not been defined. Of <br /> major concern at this site is the nearby location of many private domestic wells <br /> in the downgradient direction. It must be shown that there is no deeper <br /> contamination that could impact these wells. SJCIEHD is concerned that due <br /> to the lack of knowledge of the actual total depth of the old domestic well <br /> onsite, which had reportable concentrations of petroleum hydrocarbon <br /> contamination, and the detections of contamination in MW-13 at 230 feet <br /> below surface grade (bsg), that the condition of the groundwater below this <br /> depth is unknown and needs to be investigated. Additionally, the vertical <br /> extent of the groundwater contamination reported in wells MW-6, MW-12 and <br /> EW-2 is also unknown. It was discussed at the meeting that up to three <br /> additional wells may be needed: one 230-foot deep and one deeper than 230 <br /> feet bsg located down-gradient from the onsite source (north of MW-13); and <br /> one approximately 110-foot deep well located near MW-12. <br /> 3. An evaluation of the effectiveness of the groundwater extraction system <br /> currently operating at the site is needed. According to Ground Zero, the <br />
