6.O RECOMMENDATIONS AND OPINIONS <br /> Soil samples collected and analyzed at the areas of concern at the site did not contain detectable total <br /> petroleum compounds (TPH) as gasoline, BTEX, or MTBE Detectable concentrations of TPH as diesel <br /> and oil were below the Regional Water Quality Control Board, San Francisco Region Environmental <br /> Screening Levels (RWQCB-SF, 2008). Concentrations of metals were within expected background <br /> levels. <br /> Based on the results of the subsurface investigation, ENCON recommends no further action at this time. <br /> Encon Solutions, Inc. <br /> -13- <br />
