Three soil samples per soil boring will be submitted for laboratory analysis. The samples <br /> collected at the 25 , 30 and 35 feet bgs will be analyzed . Additional soil samples may be <br /> submitted for analysis, if required to adequately characterize the site. Field observations and <br /> sample selection will be reviewed with the PHS/EHD inspector, prior to sample submittal to the <br /> lab . <br /> Each soil sample will be sealed with Teflon® film and plastic end caps, labeled , packaged in an <br /> iced cooler, and transported with chain-of-custody documentation to a state of California-certified <br /> hazardous waste testing laboratory for analysis. The lab will analyze each of the soil samples on <br /> a standard turn-around for TPH-as-diesel , TPH-as-motor oil , and TPH-as-kerosene by EPA <br /> Method 8015M , and for TPH-as-gasoline, BTEX, MTBE , DIPE , ETBE , TAME , and TBA by EPA <br /> Method 82608 . <br /> 2 . 2 . 3 Groundwater Monitoring , Sampling and Analysis <br /> After the monitoring well seals have set for at least 72 hours, and then on a quarterly basis <br /> thereafter, the wells will be monitored and sampled . Depth-to-groundwater and free product <br /> thickness (if necessary) will be monitored using a water level indicator capable of measurements <br /> to within 0. 01 foot. Following groundwater level measurements, the wells will be purged and <br /> sampled . <br /> The wells will be purged with a pump and dedicated disposable tubing until at least three well <br /> casing volumes have been removed and/or after groundwater temperature , pH and electrical <br /> conductivity values have stabilized . Groundwater will be sampled from the wells using <br /> disposable polyethylene bailers and laboratory-supplied containers. Each sample container will <br /> 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-diesel , TPH-as-motor <br /> oil , and TPH-as-kerosene by EPA Method 8015M , and for TPH-as-gasoline , BTEX, MTBE , <br /> DIPE , ETBE , TAME , and TBA by EPA Method 82608 . <br /> 2.2 .4 Waste Storage and Disposal <br /> All waste soil generated during drilling will be contained in 55-gallon drums and temporarily <br /> stored at the site, pending analytical results and proper disposition . Equipment rinsate and <br /> purged groundwater will be contained in separate 55-gallon drums for temporary on-site storage, <br /> pending accumulation and proper disposition . <br /> 9 <br />
