3 0 REMEDIATION AND MONITORING <br /> Prior to continuous operation of the pump and treat system, an initial test run of treated water will <br /> be pumped into a holding tank and composite grab ground water samples will be collected and <br /> analyzed for TPH-g/d,BTEX and fuel oxygenates, as specified below, to verify effective treatment <br /> of the extracted ground water. During the pump and treat start-up period (first two weeks of <br /> operation), ground water influent and effluent of the treatment system, depth to ground water <br /> measurements and operational parameters(ground water flow meters,fluid level sensors,total flow <br /> indicators)will be monitored daily to ensure optimal removal of dissolved hydrocarbons and MTBE <br /> Ground water treatment operational parameters will be monitored at least once a week to monitor <br /> cleanup progress and adherence to discharge requirements The ground water treatment system <br /> components will be maintained on a weekly basis according to manufacturers' recommendations <br /> Ground water samples from the pump and treat system influent, effluent will be collected on a <br /> monthly basis for the and submitted to a California Department of Health Services (DHS)-certified <br /> laboratory for analysis of the following constituents <br /> • TPH-g/tph-d in accordance with EPA Method 8015m/5030, <br /> • Volatile aromatic hydrocarbons - benzene, toluene, ethylbenzene and xylene (BTEX) and <br /> MTBE in accordance with EPA Method 8020, <br /> • Twice annually Semi volatile and volatile compounds in accordance with EPA Method <br /> 625/624, respectively <br /> n Twice annually for metals in accordance with EPA Method 700, <br /> • Monthly for pH by EPA Method 150 1 <br /> Laboratory reports for ground water analysis,testing methods, laboratory quality assurance/quality <br /> control(QA/QC)reports,and sample chain of custody documentation will be presented in quarterly <br /> reports <br />
