Public Health Service <br /> Environmental Health Division <br /> 445 No. San Joaquin Street <br /> Stockton, CA 95202 <br /> Ref : Site Code 4359 <br /> Attn.: Mike Inf erna <br /> Dear Mr. Inf erna; <br /> We are enclosing a copy of the Site Assessment Report & Workplan <br /> for the Devincenzi property located at 21167 No. Tretheway Road, <br /> Acampo, CA. for your review and response. <br /> My associate, Dennis Allen, was on site during the work, and <br /> prepared most of the SAR. That report was completed, and the <br /> accompanying Workplan was prepared by Wm. Hunter, who will be the <br /> professional in charge of additional work conducted on the site. <br /> The laboratory results indicate that the primary source of <br /> contamination was most likely the abandoned cesspool , (or <br /> cistern, ) and not the UST. The high levels of TPH-D and oil & <br /> grease encountered, (refer to Table A, ) are not constituents of <br /> gasoline, which records indicate was the only product stored in <br /> teh UST. <br /> Water samples from two nearby domestic wells did not contain any <br /> petroleum products, and indicate that groundwater has not been <br /> impacted at this location. The high levels of coloform bacteria <br /> detected are not a result of hydrocarbon contamination; the <br /> source of that bacteria is not known. <br /> It is believed that the best method for removing the remaining <br /> contaminants is by removing additional spoil as outlined in the <br /> workplan. Because of the low viscosity and volatility of diesel <br /> and oil & grease, it is not likely that they have migrated any <br /> great distance. Re-excavation appears to be the most effective <br /> technique in this situation. <br /> We would appreciate your timely review and comment; our client is <br /> anxious to finish this project as soon as possible . If you have <br /> any questions, or wish further clarification of the contents of <br /> the report, do not hesitate to contact us . <br /> Yours r , <br /> L <br /> Will Hunter <br /> cc: A.
