Mar-21 -01 04: 10P P_03 <br /> yRj VVy <br /> --- KLEIVFtIDFR <br /> SCOPE OF WORK <br /> Permit ' and Pre-Field Activities <br /> Kleinfelder will coordinate with the San Joaquin County Public Health Services Environmental <br /> Health Division to obtain necessary boring permits prior to conducting field work. Additionally, <br /> a site-specific health and safety plan will be prepared for our personnel. Kleinfelder will request <br /> that the drilling subcontractor contact Underground Service Alert to notify local utilities of our <br /> planned activities prior to conducting field activities, <br /> FieldActivities <br /> Shallow Borings <br /> Kleinfelder proposes to advance four shallow soil probes to approximately 8 feet below the <br /> ground surface (bsg). Two of the probes will be advanced in the leach field near the closest <br /> point of discharge from the septic rank. Two additional probes will be advanced near the leach <br /> field at the furthest extent of the leach lines from the septic tank. <br /> The exploratory soil probes will be advanced using a truck mounted Geoprobe rig. The <br /> Geoprobes will be advanced using a pneumatically driven steel probe. Soil samples will be <br /> obtained by inserting a sample barrel, lined with acetate liners, into the probe. Soil samples will <br /> be continuously collected from the probes. Soil samples will be collected for potential analyses <br /> at a minimum of 4-foot intervals beginning at a depth of four feet and stopping at approximately <br /> 8 feet bgs. <br /> While sampling, an experienced environmental geologist will classify the subsurface soils <br /> generated by the advancing probes, Soil samples will be collected by cutting out the desired <br /> interval from a continuous core interval (successive 4 foot acetate liners) and sealing the ends <br /> with Teflon, sheeting and tight fitting plastic caps. Each sample will be individually labeled and <br /> placed in an iced cooler pending transport to the analytical laboratory under chain of custody <br /> protocols. Soil cuttings generated during fieldwork will be placed in plastic bags. The borings <br /> will be closed in accordance with PHS/EIID guidelines by grouting to the surface. <br /> Laboratory Analysis <br /> Two soil samples from each of the four shallow probes will be submitted to a laboratory certified <br /> by the State of California for the proposed analyses- The samples submitted for analyses will be <br /> based upon field observations and will be collected between 4 to 8 feet bgs. The samples will be <br /> analyzed for: <br /> • Total Extractable Petroleum Hydrocarbons as motor oil (TPH-mo) by EPA Method 8015M, <br /> Silica gel clean-up <br /> Total Extractable Petroleum Hydrocarbons as diesel (TPH-d)by EPA Method 8015M <br /> Silica gel clean-up <br /> 20-Yrr-5031201 LP064n01 IW00.4 Pagc A-2 <br /> Copyright 2001,Klcinfelder,Inc.
