Without the benefit of this additional oversight, the following comments are based solely on <br /> the information presented in the report. <br /> The investigation in and around the area of concern in 1993 revealed total petroleum hydrocarbons in <br /> the surface soils (from grade to approximately 3 feet below grade). This most recent investigation <br /> appears to have explored the same general area of concern but to a greater depth below grade and <br /> with the inclusion of grab groundwater samples. The results of the analytical testing indicate the areas <br /> most recently investigated to be free of hydrocarbons above the detection limits used by the laboratory. <br /> Based only on the results of the above noted investigations and making no statements or conclusions <br /> on any environmental conditions that exist or may exist at the site, PHS-EHD has amended the local <br /> contaminated site database maintained by this office to reflect this new information. As the data <br /> collected to date at the site do not indicate an impact to the groundwater resource in the area <br /> investigated, no referral will be made to the California Regional Water Quality Control Board, or any <br /> other state agency responsible for environmental regulatory oversight. <br /> If you have any questions or wish to discuss this letter in more detail, please contact Linda Turkatte, <br /> Senior REHS, at (209) 468-3441. <br /> Donna Heran, REHS, Director <br /> EnvironmentalHealthDivision <br /> Linda A.
