The vacuum gauge should be calibrated and sensitive enough to indicate a water <br /> pressure change of 0.5 inches." <br /> As stated in the EHD letter dated 30 October 2012, the State Water Resources Control Board <br /> Underground Storage Tank Cleanup Fund Five-year Review Summary Report, dated <br /> September 2012, recommended that shallow soil samples. be collected and analyzed for <br /> naphthalene to assess direct contact risks. Therefore, following the collection of soil gas <br /> samples, the EHD directs that soil samples be collected at approximately three feet below <br /> surface_grade from soil borings advanced approximately five feet from the three original soil gas <br /> borings. Analyze the soil samples for naphthalene, TPH-g,-BTEX, MTBE, TAME and 1,2-DCA. <br /> Compare soil concentrations to Environmental Screening Levels (ESLs) published by the San <br /> Francisco Bay Regional Water Quality Control Board for health risks from direct exposure. <br /> Submit a boring permit application, Master File Record form and permit/inspection fees to the <br /> EHD and complete-the fieldwork by 27.March 2013.
