File No. 20-3978-01WR6 KLE IN FELDER <br /> November 19, 1996 <br /> Hand Auger Soil Sampling <br /> A decontaminated auger will be used to advance each soil boring to the desired sampling <br /> depth. Soil samples will be obtained by driving a 2-inch diameter by 6-inch long brass <br /> tube into the soil using a slide hammer. The brass tube is then removed from the boring <br /> and sealed with Teflon sheeting and plastic end caps. The sample is then labeled, and <br /> placed in an iced cooler pending transportation to the analytical laboratory under chain of <br /> custody protocols. Sampling equipment will be decontaminated between borings and as <br /> necessary to prevent cross contamination. Water used to decontaminate equipment will <br /> be disposed of in the existing Spreckels waste water ponds. <br /> The hand auger borings will be logged, and sampled according to the protocol described <br /> in Attachment B. The soil samples collected will be field screened using an organic <br /> vapor detector as described in Attachment B, Section B-2.2. The hand auger borings will <br /> be backfilled with the cuttings generated during sampling. <br /> Laboratory Analysis <br /> One soil sample from each hand auger location will be selected for quantitative analysis <br /> will be submitted under chain-of-custody control to Sequoia Analytical Laboratories <br /> (Sequoia) of Sacramento, California. Sequoia is certified by the California Department of <br /> Toxic Substances to perform the requested analyses. It is anticipated that 35 samples will <br /> be analyzed on a normal laboratory turnaround schedule, which usually requires up to 10 <br /> working days for receipt of analytical data. Each of the soil samples will be analyzed for <br /> the following: <br /> • Total Petroleum Hydrocarbons (TPH) Extractable, fuel fingerprint method, as diesel <br /> fuel and motor oil by EPA Method 8015M <br /> • CAM 17 Metals by EPA Methods <br /> • Semi-Volatile Organic Compounds, Open Scan (includes pentachlorophenol and <br /> creosote) by EPA Method 8270 <br /> • Chlorinated Herbicides by EPA Method 8150 <br /> • Pesticides and PCBs by EPA Method 8080 <br /> 20-3978-01.WR61AIP960138 Page 2 of 4 01996, Kleinfelder, Inc. <br />
