17 July 2001 <br /> AGE-NC Project No. 97-0327 <br /> Page 4of7 <br /> are described in Section 3.6. <br /> Ground water samples will be analyzed by a State of California Department of Health Sen ices <br /> (DHS)-certified laboratory for the following constituents: <br /> • TPH-g and TPH-d by EPA Methods 8015 Modified/355015030; <br /> • BTEX compounds and MTBE by EPA Method 8020; and <br /> • Ethanol,methanol, 1,2-DCA, EDB, TBA,DIPE,ETBE, TAME, and MTBE by EPA Method <br /> 8260 Modified. <br /> 2.5. PREPARATION OF REPORT OF FINDINGS <br /> Following each ground water monitoring event, a quarterly report will be prepared presenting the <br /> findings. The quarterly reports will include a description of work performed and the results of the <br /> soilAroundwater sampling and analysis. Laboratory reports for soil/ground water analyses, testing <br /> methods, laboratory quality assurance/quality control (QA/QC)reports, and sample chain of custody <br /> documentation will be presented in a quarterly report. Conclusions and recommendations will also <br /> be included in the reports, if applicable. The report will be in a format acceptable to the PHS-EHD <br /> and the RWQCB, and will be reviewed and signed by a California Registered Geologist. <br /> 3.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist. Procedures for soil boring advancement, well installation, well development, <br /> soil/ground water sample collection,equipment decontamination and sample shipment are described <br /> below. <br /> 3.1. DRILLING `S <br /> lU <br /> Due to space limitations, soil boring P- will be advanced to approximately 60 feet bsg utilizing a <br /> Geoprobe 5400 equipped with 1.125-inch diameter probe rods and 2.15-inch diameter soil sampler <br /> using "direct push" technology. Soil borings P-1�, P-11 and MW-4 will be advanced utilizing a <br /> truck-mounted, hollow-stem drill rig and 8'/4-inch diameter hollow-stem augers. Cuttings generated <br /> during drilling activities will be placed on plastic sheeting and covered. Rinseate will be <br /> containerized in properly labeled DOT-approved 55-gallon drums, and stored on-site in an area <br /> lacking public access. Disposal alternatives will be evaluated based on results of soil and water <br /> analysis. <br /> Advanced GeoEnvirunntental,Inc. <br />
