File No. 20-3978-01.W16 KLEINFELDER January 8, 1997 A surface soil sample will be collected at another location on the Spreckels property and used to establish naturally occurring metals concentrations for comparison. The background soil sample location will be selected during field activities, and will be left to the discretion of the field geologist. However, it will likely be obtained in the former orchard located in the northwest portion of the site. Laboratory Analysis Each of the soil 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. Two soil samples from each boring location, and the background soil sample will be submitted for analysis. The samples will be selected based upon field observations, qualitative field screening results, and the depth in the boring. Each of the soil samples and the background sample will be analyzed for CAM 17 metals. 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. 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. All information gathered during the study by Kleinfelder is considered confidential and will be released only upon written authorization from the client or as required by law. California law requires a person to inform the state if a situation is encountered that can be considered an immediate endangerment to the public's health or welfare and/or to the environment. SCHEDULE Kleinfelder could initiate field activities within approximately 3 to 5 working days of receiving written authorization to proceed. Our report will be submitted for client review within approximately 10 working days of receiving analytical results. Verbal results will be provided upon our receipt of the analytical data. The estimated completion time for this scope of work is approximately 3 to 5 weeks. 10-3978-01.W16/107PE014 Page 3 of Copyright 1997, Kleinfelder, Inc.
