f <br /> FLUOR DANIEL GTI <br /> The trench will be backfilled with sand or pea gravel, capped with engineered fill, and repaved to match <br /> existing asphalt paving. Soil generated during trench excavation will be stockpiled and covered with plastic <br /> sheeting pending characterization and proper disposal. <br /> TASK 6: WATER SAMPLE ANALYSES <br /> 1 <br /> I <br /> After groundwater extraction lines are connected from the well to the remediation system, a groundwater <br /> sample will be collected as part of standard system operation and maintenance. The collected <br /> groundwater sample will be analyzed by a State-certified analytical laboratory(NEI/GTEL Environmental <br /> Laboratories in Wichita, Kansas) for BTEX methyl-tert butyl-ether(MTBE), and TPH-G by EPA methods _ <br /> 8020/8015 modified. if MTBE is detected using the EPkmethod 8020 analysis, its presence will be <br /> confirmed using EPA method 8260. <br /> TASK 7: REPORT PREPARATION <br /> Fluor Daniel GTI will prepare a report summarizing data collected under the scope of work detailed above. <br /> The report will document methods and results of the work, summarize laboratory analytical results, and <br /> include appropriate maps. This report will provide available information as outlined in SJCEHD's Site <br /> Assessment Report Checklist and will provide an evaluation of the feasibility of continuing with groundwater <br /> extraction at the site. <br /> Please contact our West Sacramento office at 916-372-4700 if you have questions or comments about this <br /> work plan. <br /> Sincerely, <br /> Fluor Daniel GTI, Inc.
