A <br /> 31 March 2004 <br /> AGE-NC Project No. 06-1156 <br /> Page 5 of 8 <br /> Section 4.6, respectively. Monitoring well installation tasks are described below. <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 ofthe sampling and analysis.Conclusions,applicable recommendations,maps <br /> and cross-sections will be included in the report. The report will be in a format acceptable to the <br /> PHS-EHD and the CVRWQCB, and will be reviewed and signed by a California Registered <br /> 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. SOIL 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 /> 4.2. SOIL SAMPLING PROCEDURES <br /> Soil samples will be collected using Geoprobe push-driven 2-inch diameter discrete and/or <br /> continuous core samplers fitted with four six-inch long brass sleeves or a four-foot long Teflon <br /> sleeve, respectively. Upon removal from the sampler, the sample sleeve is separated with a clean <br /> knife. The exposed ends of the sleeve will be covered with Teflon sheets, capped and sealed with <br /> tape. Soils encountered in the borings will be visually classified by an AGE geologist in accordance <br /> with the Unified Soil Classification System(USC S).Additionally,soil samples will be field screened <br /> for the 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 />
