20 October 2014 <br /> AGE Project No. 09-1692 <br /> Page 4 of 4 <br /> 3.1.1. Soil Sampling <br /> Soil samples will be collected at discreet two- to three-foot intervals beginning at four <br /> feet bsg using a 1.45 inch Geoprobe soil sampling assembly loaded with a two-foot <br /> acetate liner. Upon sample retrieval, a selected portion of the liner will be cut and <br /> covered with Teflon sheets, capped and sealed with tape. <br /> Appropriately sealed and labeled samples will be placed in a chilled container under ice <br /> and transported under chain-of-custody procedure to a CDPH-certified laboratory. <br /> Samples will be analyzed for the constituents listed in Section 2.3. Each sample will be <br /> labeled with boring designation, depth, time, date and sampler's initials. Soils <br /> encountered in the borings will be visually classified by AGE personnel in accordance <br /> with the Unified Soil Classification System (USCS). Additionally, soil samples will be <br /> field-screened for presence of volatile organic compounds using an organic vapor meter <br /> (OVM), equipped with flame ionization detector (FID). <br /> 3.1.2. 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 cement grout from the <br /> total depth to surface grade. Borings advanced below the groundwater table will be <br /> abandoned with grout utilizing tremmie procedures. The top three- to six-inches of the <br /> boring abandonments will be completed flush to surface grade with concrete. The <br /> SJCEHD will be notified for grout inspection at least 48 hours prior to conducting <br /> grouting procedures. <br /> 3.2. EQUIPMENT DECONTAMINATION/WASTE MANAGEMENT <br /> Prior to use, all sampling tools used for sample collection will be thoroughly rinsed with <br /> clean water after being washed with a solution of Alconox. All probing rods will be <br /> cleaned prior to advancement at each probe boring location. Any soil or water waste <br /> generated during field activities will be containerized in properly labeled DOT-approved <br /> 55-gallon drums, and stored on-site in an area lacking public access. Disposal <br /> alternatives will be evaluated based on results of soil and water analysis. <br /> 3.3. REPORTING <br /> The results of the site assessment will be submitted in a report. The report will include a <br /> description of work performed and the results of soil sampling. Conclusions and <br /> recommendations will also be included in the reports, if applicable. Reports will be in a <br /> format acceptable to CRWQCB guidelines, and will be reviewed and signed by a <br /> California Professional Geologist. <br /> Advanced Geo Environmental Inc. <br />
