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 borings, soil sampling, ground water <br /> . sampling, equipment decontamination and sample shipment are outlined below <br /> t <br /> 41 PROBE BORING ADVANCEMENT <br /> Probe borings will be advanced using a van-mounted Geoprobe 5400 direct-push probing unit <br /> equipped with 1 25-inch probing rods The Geoprobe advances soil probe borings using a hydraulic <br /> hammer to drive soil sampling tools to specified depths <br /> 42 SOIL SAMPLING COLLECTION AND ANALYSIS <br /> Soil borings will,be sampled at discreet five-foot intervals using a 1 125" Geoprobe soil sampling <br /> assembly loaded with four six-inch brass. sleeves Upon sample retrieval, the ends of the second <br /> sleeve will be covered with Teflon sheets, capped and sealed with tape I <br /> Appropriately sealed and labeled samples will be placed in a chilled container under ice and <br /> transported under chain-of-custody procedure to a DHS-certified laboratory Each sample sleeve will <br /> be labeled with the boring designation,depth, time, date and sampler's initials Soils encountered in <br /> the borings will be visually classified by an AGE geologist in accordance with the Unified Soil <br /> Classification System(USCS) Additionally, soil samples will be field-screened for the presence of <br /> Advanced GeoEnvxronmeatal,Inc <br /> a <br />
