SP12 represents an estimated 10 yards of soil, noted by W.A. Craig Inc. personnel, that . contain gasoline type odors,therefore it was covered r On March 29, 2001, an estimated 200 additional yards of soil was generated from expanding the UST area south (SP13 through SP 17). This soil was sampled by a Western Geo-Engineers sample technician working directly under Califonua Registered Geologist #3037. SAMPLE RESULTS The enclosed table contains the soil sample results documentation sampling of the excavated soil produced from product dispensing system reinoval/station remodeling All analytes tested for, from samples SP (5-7), SP (8-11), SP 12 and SP (13-17) were below laboratory lower detection. Each sample was collected in a 1 1/2-inch by 6-inch clean stainless steel sleeve. Immediately after obtaining the soil sample, it was field screened with a PID (photo-ionizing 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 analysts 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 (CoW) 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 Co#C follows the samples and documents the whom and when of possession transfer of the samples, from collection through final analysis, by California Certified Laboratorys, North State Environmental ELAP Certificate No 1753, or Kiff Analytical LLC ELAP Certificate No 2236 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 826013. 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 2
