If, however, <br /> groundwater is encountered in the boring, a grab groundwater sample will be collected <br /> from the boring. <br /> If collected, the grab groundwater sample will be collected from the boring using an <br /> unused disposable bailers or clean metal or TeflonTM bailers. The groundwater sample <br /> will be transferred into clean laboratory-supplied containers that will be closed, labeled, <br /> and placed immediately into an ice chest pre-cooled to 4°C for transport to Clayton's <br /> State-certified laboratory for analysis. All appropriate chain-of-custody documentation <br /> will be followed for the handling of the sample. <br /> Following the collection of the soil and grab groundwater samples, the boring will be <br /> sealed to the ground surface using a cement slurry containing approximately 5% <br /> bentonite. <br /> Asphalt fragments, soil cuttings and spent sample cores and waste water generated by <br /> decontamination of equipment will be placed into USDOT-approved containers that will <br /> be closed, labelled, and left onsite until appropriate disposal can be arranged based on <br /> analytical results. <br /> Task 4: Analyze the Groundwater and Soil Samples <br /> The grab groundwater sample, if collected, will be analyzed using the following <br /> methods: <br /> • United States Environmental Protection Agency (USEPA) Method 8015 (modified) <br /> for total petroleum hydrocarbons as gasoline (TPH-G) <br /> • USEPA Method 8015 (modified) for total petroleum hydrocarbons as diesel (TPH-D) <br /> and total petroleum hydrocarbons as oil (TPH-O) <br /> • USEPA Method 8260 for volatile organic compounds (VOCs) <br /> The soil samples will be analyzed using the following methods: <br /> • USEPA Method 8015 (modified) for TPH-G <br /> • USEPA Method 8015 (modified) for TPH-D and TPH-O <br /> • USEPA Method 8260 for VOCs <br /> KSEM7701271L7O127M.ISO <br />
