SAMPLE RESULTS The enclosed table contains the soil sample results documentation sampling of the excavated soil produced from product dispensing system removal/station remodeling All analytes tested for from samples SP (5-7), SP (8-11) and SP 12 were below laboratory lower detection Each sample was collected in a 11/2-inch by 6-inch clean stainless steel sleeve Immediately after obtaining the soil sample, it was field screened with a PID (photo-iomzing detector) containing a 10 6 ev bulb, for the presence of volatile organic compounds, gasoline ranges The sample sleeve was then sealed with teflon sheets and plastic end caps to prevent the loss of VOC's (volatile organic compounds) The steel sleeve was then labeled with site ID, sample ID, date and time sampled, name of sampler, and laboratory analysis needed Once labeled, the sample was placed into a ziplock baggy, sealed and placed into an ice chest containing ice to keep the sample cool until delivery to the analytical laboratory A Chain of Custody (CofC) was completed documenting the site ID, sample ID's, date and time samples were obtained the laboratory analysis needed, and the name of the sampler The CofC follows the samples and documents the whom and when of possession transfer of the samples, from collection through final analysts by California Certified Laboratory, North State Environmental ELAP Certificate No 1753, see Appendix A SAMPLE ANALYSIS • The three UST's contained unleaded gasoline San Joaquin County Health and the State of California require that the soil samples be analyzed for Total Petroleum Hydrocarbons as gasoline (TPHg), Benzene, Toluene, Ethylbenzene and Xylenes and the fuel oxygenants (Ethanol, MTBE, TBA, DIPS, ETBE and TAME) using EPA methods 8260B SOIL DISPOSITION It is Western Geo-Engineers understanding that Wickland Property was responsible for the disposition of contaminated soils only Soils that were found to be below laboratory lower detection limits for gasoline range hydrocarbons are not the responsibility of Wickland Properties Over-excavation soil pile sample results SP (1-4) showed this soil to contain gasoline range hydrocarbons This soil (60 yards) was profiled to and disposed of at Forward Landfill, 9999 South Austin Road, Manteca, California as non-hazardous waste SP12 (10 yards) although below laboratory lower detection limits contained petroleum odors as described by W A Craig personnel will also be disposed of at Forward Landfill, under the same profile agreement Excavated soil piles SP (5-7) and SP (8-11) contained no petroleum odors and tested below laboratory lower detection limits are not the responsibility of Wickland Properties Disposition of . this soil is at the discretion of the Prestige Oil and/or Lincoln Village Properties 2 R-603 exsosil samples 7-2000
