PHS/EHD has the following <br /> comments for your consideration. <br /> PHS/EHD agrees that a minimum of two additional monitoring wells are necessary and <br /> that free product should be removed. <br /> The workplan suggested that sampling occurs at 10 foot intervals. In order to better <br /> characterize soil conditions PHS/EHD emphasizes that sampling should occur at a <br /> minimum of 5 foot intervals and/or changes in lithology. Sample selection for laboratory <br /> analysis should be based on field observations, using field instrumentation screening, <br /> during drilling. <br /> The workplan did not indicate that soil samples would undergo lead analysis. The <br /> former underground storage tank is reported to have contained leaded gasoline; <br /> therefore, please analyze samples for total Iead, using the W.E.T. when applicable. <br /> The workplan included one permit application for the installation of two monitoring <br /> wells. A total of two permit applications are required because placement of monitoring <br /> wells involves two parcels of property; MW-4 is located on APN 047-119-02 and MW-5 is <br /> located on APN 047-119-28. Enclosed is a copy of permit #92-0544 for the installation <br /> of MW-4. Please submit an additional permit application for the installation of MW-5. <br /> Please contact PHS/EHD 48 hours in advance, to schedule a site inspection. <br /> A Division of San Joaquin County Hcalth Cafe Services 10 <br />
