FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist Procedures for the advancement of the monitoring well pilot borings, soil <br /> sampling, ground water sampling, monitoring well completion, equipment decontamination and <br /> sample shipment are outlined below <br /> 3 1 MONITORING WELL PILOT BORINGS AND SOIL SAMPLING <br /> Soil borings will be advanced utilizing a truck-mounted, hollow-stem drill rag and 8-inch diameter <br /> hollow-stem augers Cuttings and rinseate generated during drilling activities will be containerized <br /> in properly labeled Department of Transportation (DOT)-approved 55-gallon drums or in roll-off <br /> storage bins, and stored on-site in an area lacking public access Disposal alternatives will be <br /> evaluated based on results of soil and water analyses <br /> Soil samples will be collected from each soil boring at five-foot intervals beginning at a depth of <br /> 5 feet bsg using a California modified split-spoon sampler fitted with three 2-inch diameter, 6-inch <br /> long brass sleeves Following sample collection, the exposed ends of the leading or other selected <br /> sleeve will be labeled with the boring location, depth, time, date and sampler's initials, the <br /> appropriately sealed and labeled samples will be placed under ice in a chilled container and will be <br /> transported under chain-of-custody to a DHS-certified laboratory for analysis The soil in the two <br /> remaining sleeves will be visually classified by an AGE geologist in accordance with the Unified <br /> Soil Classification System (USCS) and field-screened for the presence of volatile organic <br /> compounds using an organic vapor meter(OVM) equipped with a photo-ionization detector(PID <br /> Thermo Environmental 580, 10 OeV [or equivalent], calibrated to isobutylene) <br /> i <br /> Advanced GeoEnviron mental,Inc <br />
