Mar-21-01 04: 10P P. 03 <br /> RLLJ V V y <br /> - ---- KLEI .VFELOFR <br /> SCOPE OF WORK <br /> Permittl9lLand Pre-Field Activities <br /> Kleinfelder will coordinate, with the San Joaquin County Public Health Services Environmental <br /> Health Division to obtain necessary boxing 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 /> Field Activities <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 tank. 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 froiU 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 udder 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/EHD 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 fol 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 Hydmcarbons as diesel (TPH-d)by EPA Method 8015M <br /> Silica gel clean-up <br /> 20-YP1•503 011WO04 Pale A•2 <br /> Copyright 2001.Klcinfelder,Inc.
