samples will be transported to a state-certified laboratory for analysis. The samples will be <br /> analyzed for total petroleum hydrocarbons(TPH as gasoline,diesel and motor oil).Tile soil <br /> boring will be completed as a groundwater monitoring well. Selection of soil samples for <br /> analysis will be based upon field observations and measurements. <br /> After completion, groundwater samples will be collected from each well. In addition to <br /> TJPH, the groundwater sample will be analyzed for chlorinated pesticides (EPA SOSO). If <br /> the initial sampls are uon-detect for all tested constituents, then a confirming groundwater <br /> samples will be collected in approximately 30 days. <br /> 4.0 PROCEDURES <br /> To meet the project objectives, the following procedures will be performed: <br /> 1) Prepare a Site Health and Safety Plan in accordance with the Occupational Safety <br /> and Health Guidance Manual for Hazardous Waste Site Activities - Prepared by <br /> National Institute for Occupational Safety and Health, Occupational Safety and <br /> Health Administration, U.S. Coast Guard and U.S. Environmental Protection <br /> Agency, October 1485. <br /> 2) Notify the San Joaquin County Environmental Public Health 'Services - <br /> Environmental Health Division (PHS/E14D) and the District Attorney 48 hours prior <br /> to commencement of any work. <br /> 3) Initially, drill three (3)soil borings. All borings will be drilled using a truck-mounted <br /> drill rig equipped with continuous-flight, 8-inch diameter hollow-stem augers. The <br /> borings will be drilled to a deptlr of approximately 20 feet. The proposed <br /> boriug/nronitoling well locations illustrated on Figure 2. <br /> 4) Obtain sail samples using a split-tube sampler loaded with three pre-cleaned brass <br /> sleeves. Samples will be obtained continuously until Qrot�ndwater is encountered. <br /> 5) Preserve- soil in the lead brass sleeve by covering both ends widr aluminum foil, <br /> capping, and sealing with tape. <br /> 6) Label and log soil samples on a chain-of-custody form. <br /> 7) Store the samples under ioe and transport the samples in a chilled container to a <br /> State certified laboratory for analysis. <br /> 8) Lag auger returns in accordance with the Unified Soil Classification System, <br /> 9) Screen auger returns and soil sample duplicates for the presence of volatile organics <br /> S¢q•p1L1E1 �ftLrNiQ kl+W t"P$ir RA.Wd'A"A'95 <br /> V _d 0©!O 9S6 bac, ON ADV HOS Hd9 t =V S66 t-r?-S <br />
