GROUND WATER SAMPLING AND ANALYSIS <br /> Following the installation of the wells, ground water monitoring and sampling activities will be <br /> conducted on a quarterly basis until directed to modify or discontinue the monitoring program by the <br /> SJCEHD or CVRWQCB. Monitoring activities will include recording depth to ground water <br /> measurements and collection of ground water samples for laboratory analysis by a DHS-certified <br /> laboratory for the following analytes: <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) and diesel (TPH-d) in <br /> accordance with EPA Methods 3550/8015 Modified; and <br /> • Benzene, toluene, ethyl benzene and total xylene (BTEX) and di-isopropyl ether (DIPE), <br /> ethyl tertiary-butyl ether(ETBE),methyl tertiary-butyl ether(MTBE),tertiary-amyl methyl <br /> ether (TAME), tertiary butanol (TBA), methanol, ethanol, ethylene dibromide (EDB) and <br /> 1,2-dichloroethane(1,2-DCA) in accordance with EPA Method 8260. <br /> YVI <br /> 9lrovnd�c+iat�' J MOM <br /> Laboratory reports of.469 analyses, testing methods, laboratory quality assurance/quality control <br /> (QA/QC)reports,and sample chain of custody documentation will be presented in a report Ground <br /> water sample collection protocols are described in Section 4.4. <br /> 3.5. PREPARATION OF REPORT OF FINDINGS <br /> Following each ground water monitoring event, a quarterly report will be prepared presenting the <br /> findings.Each report will include a description of work performed and the results of the groundwater <br /> sampling and analysis. Laboratory reports for ground water analyses, testing methods, laboratory <br /> quality assurance/quality control(QA/QC)reports,and sample chain of custody documentation will <br /> be presented in the quarterly report. Conclusions and recommendations will also be included, if <br /> applicable. The report will be in a format acceptable to the SJCEHD and CVRWQCB, and will be <br /> 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 for the well installation,well development,sampling are described <br /> below. <br /> Advanced GeoEnvironmental,Inc. <br />
