Work Plan for VenHcation Assessment 2 <br /> Semis 5tm No 1288 5110 Padfic Avenue Stockton Califamh October 21 1 M <br /> For logging purposes, soil samples will be collected using a 4-foot-long continuous core sampler lined <br /> with a 1 75-inch-diameter acetate tube Soil from each 4-foot sampling Interval will be placed in a plastic <br /> bag and will be monitored with a phototonlzation detector(PID)for the presence of volatile organic <br /> ' compounds For each 4-foot interval, site lithology will be documented on drilling logs according to the <br /> Unified Soil Classification System <br /> ' For analytical purposes, one 6-inch-long acetate tube of soil will be capped at each end with a Teflon <br /> sheet and a plastic lid Each lid will be secured with sample tape, and the sample will be labeled and <br /> placed on ice pending delivery to a State-certified laboratory <br /> ' All bonngs will be abandoned by backfilling with cement/bentonite grout or bentonite chips hydrated in <br /> place All sampling equipment will be cleaned between sampling intervals with non-phosphate <br /> ' detergent, followed by successive rinses of tap and distilled water This method decontaminates the <br /> sampling equipment and prevents cross contamination between sampling events <br /> ' All field work will be conducted in accordance with IT Corporation's Health and Safety Plan, which is <br /> provided in Attachment 4 <br /> Laboratory Analyses <br /> ' The soil samples will be analyzed by a state-certified laboratory,according to the constituents required <br /> by the PHS/EHD (Fable 1) <br /> Table 1: Constituents of Concern <br /> 1.000-Gallon New/Used-oll USTs 10,000-Gallon Gasoline USTs <br />' EPA Method 8015 modified-TPH as EPA Method 8015 modified-TPH as gasoline <br /> diesel/motor oil <br /> EPA Method 6010- LUFT metals EPA Method 8020- BTEX/MTBE <br /> EPA Method 413 2- Oil and Grease EPA Method 6010-Lead <br /> EPA Method 8010- Purgeable Halogenated EPA Method 82608-VOCs and Oxygenates <br /> Hydrocarbons <br /> EPA Method 8270-Semivolatlles/PAHs <br />' EPA Method 8080- PCBs <br /> TPH-Total Petroleum Hydrocarbons <br /> LUF7-Leaking Underground Fuel Tanks <br /> PAHs-Polyaromabc hydrocarbons <br /> PCBs-Polychlonnated biphenols <br /> 13TEX-Benzene,toluene, ethylbenzene, total xylenes <br /> MTBE-Methyl tertiary-butyl ether <br /> VOCs-Volatile organic compounds <br /> 1288WFIM SM rr CORPORATION <br />
