19 November 1999 <br /> AGE-NC Project No 99-0657 <br /> Page 7 of 10 <br /> 3 5 REPORT PREPARATION <br /> Upon completion of field work and receipt of final laboratory analysis, a report will be prepared <br /> presenting the findings of the investigation The report will include a description of the work <br /> performed and results of the sampling and analysis Conclusions and applicable recommendations <br /> will be included in the report The report will be in a format acceptable to the PHS-EHD and <br />' CVRWQCB, and will be reviewed and signed by a California Registered Geologist <br /> 4.0. 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 probe borings, soil sampling, ground <br /> water sampling, monitoring well installation and development, equipment decontamination, and <br /> sample shipment are outlined below <br /> 4 1 PROBE BORING ADVANCEMENT <br /> Probe borings will be advanced using AGE's 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 /> or pneumatic hammer to drive soil and ground water sampling tools to specified depths <br /> 42 SOIL SAMPLING PROCEDURES <br />' Soil samples will be collected using Geoprobe push-driven 2-inch diameter sampler containing four <br /> six-inch long brass sleeves, and/or a continuous core sampler containing a four-foot long Teflon <br /> sleeve Upon removal from the sampler,the sample sleeve is separated with a clean soil 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 /> Idepth, 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 /> I <br /> I <br /> Advanced GeoEmlronmental,Inc <br />
