' 03 April 2002 <br /> AGE-NC Project No. 97-0333 <br /> ' Page 9of12 <br /> ' EPA Method 8260 Modified; <br /> ' Laboratory reports for ground water analyses,testing methods,laboratory quality assurance/quality <br /> control(QA/QC)reports, and sample chain of custody documentation will be presented in a report <br /> with the findings and recommendations. <br /> ' 3.5. REPORT PREPARATION <br /> ' Following installation of multi-level wells, a report will be prepared presenting the findings. The <br /> report will include a description of work performed and the results of the soil/groundwater sampling <br /> ' and analysis. Conclusions and recommendations will also be included in the reports, if applicable. <br /> The report will be in a format acceptable to SJCEHD and RWQCB guidelines,and will be reviewed <br /> 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 well installation,well development,soil and ground water <br /> ' sample collection,equipment decontamination and sample shipment procedures are described below. <br /> 4.1. DRILLING <br /> ' Soil borings will be advanced utilizing a B-95 truck-mounted, hollow-stem drill rig and 8-inch <br /> diameter hollow-stem augers. Cuttings and rinseate generated during drilling will be containerized <br /> in properly labeled DOT-approved 55-gallon drums, and stored on-site in an area lacking public <br /> access. Disposal alternatives will be evaluated based on results of soil and water analysis. <br /> Soil samples will be collected from MW-7, MW-9 and MW-11 at five-foot intervals,beginning at <br /> ' a depth of 15 feet bsg. Soil samples will be continuously collected from MW-8, MW-10, MW-12 <br /> and MW-13 utilizing a five-foot macro core sampler and will be described and recorded on boring <br /> logs. The macro core sampler will be driven by dropping a 140-pound weight from a height of 30 <br /> ' inches. Selected soil samples will be submitted to a State of California Department of Health <br /> Services (DHS)-certified laboratory for analysis for the following constituents:: <br /> • TPH-g in accordance with EPA Method 8015 Modified/5030; <br /> • BTEX compounds and MTBE in accordance with EPA Method 8020; <br /> ' Advanced GeoEnvironmental,Inc. <br />
