y <br /> CAMBRIA <br /> . s <br /> (greater than 1,700 feet east of the 7-Eleven site) and one private well was identified on Toste <br /> Road,southwest of the 7-Eleven site. <br /> No.surface water bodies were identified within a 2;000-foot radius of the site. The locations of <br /> these wells are depicted on Figured. <br /> Quarterly Groundwater Monitoring: A quarterly groundwater monitoring program has been in <br /> place at this site since March 2403. .Currently all wells at the site are gauged and sampled <br /> quarterly and analyzed for TPHg, benzene, toluene, ethylbenzene, and xylenes (BTEX), MTBE, <br /> TBA, tertiary amyl methyl ether (TAME), di-isopropyl ether (DIPE), and ethyl tertiary butyl <br /> ether (ETBE). Additionally, wells MW-.I .through MW4 are sampled annually in the third <br /> quarter for ethanol. <br /> The scope of work proposed in the above-referenced work plan and work plan addendum <br /> included the installation of three shallow groundwater monitoring wells and one soil boring by. <br /> Cone Penetration Test (CPT) to assess the lateral.and vertical extent of gasoline constituent <br /> impact in soil and groundwater beneath the site. The results of this investigation are presented <br /> below. <br /> INVESTIGATION RESULTS <br /> Personnel Present: Staff Geologist. John- Gerbrandt directed the field activities, <br /> working under the supervision of California Professional <br /> Geologist Joe Neely. <br /> f <br /> Permits: Drilling permits No. 40933 and 40934 were obtained from <br /> SJCEHD.(Appendix A). <br /> Drilling Company: Gregg Drilling and Testing, Inc. (Gregg) and Gregg In Situ of <br /> Martinez,California(C57 License Nos.485165 and 656407). <br /> Drilling Dates: January 27 and 28,2005 and March 4 and 7,2005. <br /> Drilling Methods: Hollow-stem auger(HSA)and CPT. S <br /> Number of Borings: Three HSA borings (MW-5 though MW-7) and one CPT boring <br /> (SB-1) were; drilled. Borings MW-5 though MW-7 were <br /> f 1661 3 <br /> 1 <br />
