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 the results of the sampling and analysis. Also, conclusions and applicable <br /> recommendations will be included-in the report. The reportwill be in a format acceptable to the <br /> SJCEHD and 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 to be implemented to advance soil borings, collect soil and <br /> groundwater samples, install and develop monitoring wells, sample-handling, sample analysis;and <br /> equipment decontamination are outlined below.- <br /> 4.1. <br /> elow.4.1. 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 /> 4.1.1. SOIL SAMPLING COLLECTION AND ANALYSIS <br /> Relatively-undisturbed soil samples will be collected at all borings using a Geoprobe soil sampling <br /> assembly loaded with pre-cleaned 1.125-inch by 6-inch brass sleeves. Upon soil sample retrieval, <br /> the sample sleeve will be separated with a clean soil knife. The exposed ends of the second sleeve <br /> will be covered with Teflon sheets,capped and sealed with tape. 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 of volatile organic <br /> compounds using an OVM. <br /> Following sample collection, each preserved soil sample 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 procedure to a DHS-certified <br /> laboratory. <br /> Advanced GeoEnvironmental,Inc. <br />
