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 soil borings, soil sampling, ground water <br /> sampling, monitoring well Installation and development, equipment decontamination, and sample <br />' shipment are outlined below <br /> 41 SOIL SAMPLING <br /> Proposed monitoring well borings will be completed using hollow-stem auger drilling techniques <br /> Relatively undisturbed soil samples will be collected at five-foot intervals in each of the borings <br /> using a California modified split-spoon sampler fitted with 2-mch diameter, 6-inch long brass <br /> sleeves Upon removal from the sampler, the sample sleeve Is separated with a clean knife The <br /> exposed ends of the sleeve will be covered with Teflon sheets, capped and sealed with tape Soils <br /> encountered in the borings will be visually classified by an AGE geologist in accordance with the <br /> Unified Soil Classification System (USCS) Additionally, soil samples will be field screened for the <br /> presence of volatile organic compounds using an OVM <br /> Following sample collection, each preserved sample sleeve will be labeled with the boring location, <br /> depth, time, date and sampler's initials Appropriately sealed and labeled samples will be placed in <br /> a chilled container under ice and transported under chain-of-custody to a DHS-certified laboratory <br /> Advanced GeoEnvironmental,Inc <br />
