APPENDIX C <br />' PROTOCOL FOR SOIL SAMPLING <br /> FOR CHEMICAL ANALYSIS <br /> 1.0 INTRODUCTION <br />' This protocol describes procedures to be followed for collecting soil-core samples and <br /> conducting soil-field screening in conjunction with the drilling of soil borings in the vicinity of <br />' the project site Selected soil-core samples will be submitted to a designated subcontracted <br /> laboratory for chemical analysis The subcontracted laboratory must be certified by the <br /> California Department of Health Service (DHS) for the analyses requested. The procedures <br /> ' presented herein are intended to be of general use. As the work progresses and if warranted, <br /> appropriate revisions will be made and approved in writing by the Boyapan &Ross, Inc (B&R) <br /> ' project manager <br /> 2.0 ADVANCEMENT OF BORINGS <br /> The advancement and backfilling of soil borings will be in accordance with the protocol <br /> presented in Appendix B <br /> ' 3.0 SAMPLING AND LOGGING <br /> Soil-core samples will be collected in accordance with the protocol presented in Appendix B <br /> ' The sampler will be washed with detergent-water solution to remove any soil present and then <br /> it will be rinsed with tap water prior to and between sampling. Upon disassembly of the soil <br /> sampler, the B&R field geologist or engineer will take charge of the core. The core will be <br /> ' quickly inspected for color, appearance, and composition and then capped. Capping will be <br /> done with PTFE sheeting and covered by polyethylene caps. Capped samples will be sealed <br /> with rubber or polyvinylchlonde (PVC) tape and will be labeled, enclosed in plastic bags, and <br /> stored in ice-cooled chests until delivered to the laboratory <br /> Sample containers will be labeled using waterproof ink and having the following information <br /> ' written on them. <br /> A.
