r <br /> 13) Collect one groundwater sample from each boring on the Jimco property via <br /> hydropunch or similar method. l <br /> 14) Complete two borings as two-inch diameter mol itoring well. The wells will be <br /> completed in accordance with the well design depicted in Figure 3. <br /> 15) Backfill the remaining borings with neat cement. <br /> 16) Survey the top of each well casing to determine he elevation relative to existing <br /> wells. <br /> 17) No sooner than 48 hours after installation, measure to the nearest 0.01 foot, the <br /> static water level in the new wells. <br /> 18) Remove standing water from each well. A bailer cr submersible pump will be used <br /> to surge and purge each well. A minimum of three weldivolummes of water will be <br /> removed from each well to stabilize pH, temperature and conductivity. Parameters <br /> will be measured at one-gallon intervals. After wells have stabilized, samples will be <br /> collected using disposable plastic bailers. <br /> 19) Store purge water in 55 gallon DOT drums on-site) pending analytical results. <br /> 20) Label and log water samples on a chain-of-custod 'form. <br /> 21) Store soil and.groundwater samples in a chilled container and transport to a state- <br /> certified laboratory for analysis. Water samples will�Ilccordance <br /> e analyzed far TPH as gasoline <br /> and diesel and volatile aromatics (BTE&CX), rn with EPA methods <br /> 5030/8015 and 602, respectively. j <br /> 21) Prepare a report detailing the procedures and results of the investigation. Upon <br /> approval of the Client, the report will be submitted to the PHS /EHD and the Central <br /> Valley Regional Water Quality Control Board (CVRWQCB). <br /> The opportunity to prepare this work plan is greatly appreciated.
