NOV <br /> 3.x.;3 � orndwaer orritorin � � !� and � <br /> After the new monitoring well seals have set, and on a quarterly basis thereafter, the new wells <br /> and the existing wells will be monitored and sampled, Depth-tri-grort dwator and free product <br /> thickness ifnecessary)will be monitored using a mater level indicator capable of measurements <br /> to within 0.0foot. Following groundwater level measurements, the galls will be purged and <br /> sampled, <br /> The wells will be purged with decontaminated pumps and dedicated disposable tubing until at <br /> least three well casing volumes have been removed and/or after groundwater temperature, ply <br /> and electrical conductivity values have stabilized. Groundwater will be sampled from the wells <br /> using disposable polyethylene bailers and laboratory-supplied containers. Each sample container <br /> will be labeled, packaged in an iced cooler and transported for analysis with chain-of-custody <br /> documentation to a state of California certified hazardous waste testing laboratory. The lab will <br /> analyze each groundwater sample on a standard turn-around for TPH-as jet fuel, T PH-as- <br /> gasoline and BTEX by EPA Method 8020/8015M, and for IVITBE, DIPE, ETBE, TAME, and TBA <br /> by EPA Method 30 . <br /> 3.3 Waste Storage and i posal <br /> All waste soil cuttings generated during drilling will be stockpiled using a base and cover of plastic <br /> sheeting, and stored temporarily on-site, pending waste profiling and proper disposition. <br /> Equipment rinsate water and purged groundwater will be contained in 55-gallon drums for <br /> temporary on-site storage, pending waste profiling and proper disposition, <br /> 3,4 Project Reporting <br /> The results of the additional site investigation will be documented in an environmental corrective <br /> action report. The report will be prepared and stamped by a state of California Registered <br /> Geologist and submitted to EHD and RWQCB. <br /> 10 <br />
