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 laboratory analyses. Conclusions, applicable recommendations,maps <br /> and cross-sections will be included in the report, as will copies of the laboratory reports, testing <br /> methods,laboratory quality assurance/quality control(QA/QC)reports,and sample chain of custody <br /> documentation.The report will be in a format acceptable to the PHS-EHD and the CVRWQCB,and <br /> 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 borings, soil sampling, ground water <br /> sampling, equipment decontamination and sample shipment are outlined below. <br /> 41. PROBE BORING ADVANCEMENT <br /> Probe borings will be advanced using a van-mounted Geoprobe 5400 direct-push probing unit <br /> equipped with 1.125-inch probing rods.The Geoprobe advances soil probe borings using hydraulic <br /> pressure and a pneumatic hammer to drive soil sampling tools to specified depths. <br /> 4.2. SOIL SAMPLING COLLECTION AND ANALYSIS <br /> Soil borings will be sampled at discreet five-foot intervals using a 1.25" 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. <br /> Appropriately sealed and labeled samples will be placed in a chilled container under ice and <br /> transported under chain-of-custody to a DHS-certified laboratory.Each sample sleeve will be labeled <br /> with the boring designation,depth,time,date and sampler's initials. Soils encountered in the borings <br /> will be visually classified by an AGE geologist in accordance with the Unified Soil Classification <br /> System(USCS).Additionally,soil samples will be field screened for the presence ofvolatile organic <br /> compounds using an organic vapor meter(OVM), equipped.with photo-ionization detector(PID). <br /> Advanced GeoEnvironmental,Inc. <br />
