Fii <br /> r <br /> Workplan And Health And Safety Plan BSK.lob 01-40-0433 <br /> Soil Investigation March 9, 1998 <br /> F;;' <br /> 1755 East Yosemite Avenue Page 2 <br /> Manteca, California <br /> a <br /> • Drill one soil boring to a depth of 15 feet below ground surface (based on an <br /> anticipated depth to water of 20 feet), collecting soil samples at five-foot intervals, <br /> starting at a depth of 5 feet. The boring will be backfilled with a sand-cement <br /> grout or neat cement. ' <br /> • Soil cuttings will be stored in 5-gallon containers and will remain on-site in the <br /> custody of the client. Costs for handling/disposal of the drums are not included. <br /> Recommendations for disposal can be provided following the receipt of analytical <br /> results. <br /> Submit two soil samples for chemical analysis of Total Petroleum Hydrocarbons <br /> i as referenced to gasoline (TPHg) and benzene, toluene, ethylbenzene and xylenes <br /> ' (BTEX). The soil samples will be submitted to BSK Analytical Laboratories in <br /> Fresno (ELAP Certification #I 180) for chemical analyses. ; <br /> • Submit a brief letter report presenting o r observations and analytical results. <br /> F,' The soil boring will be completed using hand auger methods and soil samples will be collected � <br /> within brass or stainless steel sample tubes by driving a core sampler in advance of the auger. <br /> , Based on our review of the Phase 1, the soils of the sub ect property are amenable to such <br /> F, methods in the area of the removed UST, where hardpan soils would have been penetrated by the <br /> excavation. Soil samples obtained for chemical analyses will be accompanied to the analytical <br /> Flaboratory by a Chain-of-Custody form (COC). COC rms will be initiated at the time of <br /> sampling. Duplicate COC forms will be placed in the project file. COC documentation will <br /> include the following information: <br /> -- Name of sampler. <br /> -- Sample I.D. numbers. <br /> -- Time of sample acquisition. <br /> -- Requested analyses. <br /> -- Remarks as warranted. <br /> -- Signatures, times and dates of custody transfer. <br /> i ! Sampling personnel will be responsible for the protection and custody of the samples until they I <br /> are relinquished. When sample custody is transferred, the respective individuals relinquishing <br /> and receiving the samples will sign, date, and record th time on the COC form <br /> F1Between soil sampling attempts, the sampler will be washed in a solution of laboratory-grade <br /> detergent, rinsed with clean water, and reassembled with clean sample liners to minimize the ' <br /> Fill! potential for spreading contaminants among samples. <br /> i <br /> I <br /> IJ <br /> : I <br />
