Ground Water Sample Collection and Analysis <br /> Following installation and development of the monitoring wells, one ground water monitoring and <br /> sampling event will be conducted at the site. Ground water samples will be collected from the <br /> proposed monitoring wells and submitted for laboratory analysis. Ground water samples will be <br /> analyzed for TPH-g, TPH-d, BTEX and fuel oxygenating compounds following the protocols <br /> presented in Section 3.3.Additionally,monitoring activities will include recording depth to ground <br /> water measurements. Ground water sample collection procedures are described in Section 4.5. <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,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 borings, soil sampling, ground water <br /> sampling, equipment decontamination and sample shipment are given below. <br /> 4.1. BORING ADVANCEMENT AND SOIL SAMPLE COLLECTION <br /> Borings will be advanced using a truck mounted drill rig equipped with 8:25-inch hollow-stem <br /> augers. Relatively undisturbed soil samples will be collected at five-foot intervals in each of the <br /> borings using a California modified split-spoon sampler fitted with 2-inch diameter, 6-inch long <br /> brass sleeves.Upon removal from the sampler,the sample sleeve is separated with a clean knife.The <br /> exposed ends of the sleeve will be covered with Teflon sheets, capped and sealed with tape.
