File No. 20-3978-O1.WR7 KI K L E IN F E L D E R November 22, 1996 custody protocols. The one-foot deep hand auger borings will be backfilled with the auger returns. The hand auger borings will be logged, and sampled according to the protocol described in Attachment B. The soil samples collected will be field screened using an organic vapor detector as described in Attachment B, Section B-2.2. The hand auger borings will be backfilled with the cuttings generated during sampling. Laboratory Analysis Each of the samples selected for quantitative analysis will be submitted under chain-of- custody control to Sequoia Analytical Laboratories (Sequoia) of Sacramento, California. Sequoia is certified by the California Department of Toxic Substances to perform the requested analyses. It is anticipated that samples will be analyzed on a normal laboratory turnaround schedule, which usually requires up to 10 working days for receipt of analytical data. The soil samples will be analyzed for the following: Sample Location Number of Sample Analysis Samples Analyzed Former Fuel/Steam 20 soil samples • TPH-Extractable as diesel and motor Line (2 per boring) and 3 oil (fuel fingerprint) by EPA Method water samples 8015M • TPH-Purgeable, BTEX, MTBE by EPA Methods 8020/8015M Almond Orchard 25 soil samples • Organochlorine Pesticides and PCBs by EPA Method 8080 • Herbicides by EPA Method 8150 REPORT PREPARATION Upon completion of the soil sampling and our receipt and review of the analytical results, a report will be prepared for client review. The report will include: • A description of field activities, observations, and protocols; - • Lithologic logs and, if appropriate, interpreted geologic cross sections; • Tabularized results of soil sample analysis with copies of certified analytical laboratory results with chain-of-custody documentation; • Conclusions and recommendations. 20-3978-0I.WR7/MR960268 Page of 0/996, Kleinfelder, Inc.
