... .w <br /> 05 October 2012 <br /> AGE-NC Project No. 10-1821 <br /> Page 3 of 4 <br /> Samples will be collected from each location at a depth of approximately four to six feet. <br /> Below surface grade (bsg). Each sample will be collected using a soil sampler and <br /> stainless steel or acetate sleeves. Upon sample retrieval,the ends of a selected sleeve will <br /> be covered with Teflon sheets, capped and sealed with tape. Appropriately sealed and <br /> labeled samples will be placed in a chilled container under ice and transported under <br /> chain-of-custody procedure to CalTech Environmental Laboratories, a California <br /> Department of Public Health certified laboratory located in Paramount, California. The <br /> collected soil samples will be analyzed for: <br /> • Total Petroleum Hydrocarbons quantified as diesel(TPH-d)in accordance with EPA <br /> Method 8015 Modified. <br /> • Benzene, toluene, ethyl benzene and xylenes (BTEX) in accordance with EPA <br /> Method 82608. <br /> A copy of the laboratory reports of soil sample analyses,testing methods, laboratory quality <br /> assurance/quality control (QA/QC) reports, and sample chain of custody documentation <br /> will be sent via email from the laboratory directly to SJCEHD and also presented in a brief <br /> written report to SJCEHD. <br /> EQUIPMENT DECONTAMINATION <br /> Prior to use, all tools used for sample collection will be thoroughly rinsed with clean water <br /> after being washed with a solution of Alconox. All hand-auger tools will be cleaned prior to <br /> advancement at each boring location. <br /> BORING ABANDONMENT <br /> All soil borings will be permanently sealed to prevent vertical migration of potential <br /> contaminants. Soil borings shall be abandoned by backfilling with a portland cement slurry <br /> from the total depth to surface grade. <br /> Advanced Geo Environmental,Inc. <br />
