�• Based on field observations, PID measurements, and consultation with the PHS/EHD inspector, a <br /> total of seven soil samples were sealed with Teflon® paper and plastic end caps, labeled and <br /> transported in an iced cooler with chain-of-custody documentation to Kiff Analytical, LLC (Kiff), a <br /> state of California certified hazardous waste testing laboratory (Certification #2236) <br /> After encountering saturated soil and static groundwater in the soil boring at a depth of <br /> approximately 78 5 feet bgs, the boring was then advanced to a total depth of 83 feet bgs so that a <br /> groundwater-grab sample could be collected To collect the groundwater-grab sample, a two-inch <br /> diameter polyvinyl chloride (PVC) temporary well was constructed and installed in the borehole <br /> The temporary well consisted of 10 feet of flush-threaded and machine-slotted (0 020-Inch) well <br /> screen spanning approximately five feet above and five feet below the static groundwater level <br /> Blank PVC casing was threaded into the top of the well screen and extended to the surface <br /> Neither a sand pack nor a well seal was installed in the temporary well <br /> Prior to groundwater-grab sampling, approximately five gallons of groundwater was purged from the <br /> temporary well with a bailer During purging, groundwater temperature, pH and electrical <br /> conductivity were recorded Once the groundwater in the temporary well was purged and had <br /> recharged to at least 90% of its original groundwater column thickness, a groundwater-grab sample <br /> was collected The groundwater-grab sample was collected with a disposal bailer and poured into <br /> • laboratory-supplied containers The containers were labeled and transported in an iced cooler with <br /> chain-of-custody documentation to Kiff for analysis <br /> Once the soil and groundwater-grab sampling was completed, the temporary well was removed and <br /> the soil boring was sealed with 20 1 cement bentonite grout, installed to the bottom of the borehole <br /> using a tremae pipe Following borehole abandonment, the surface composition was restored <br /> Waste soil generated during the drilling of the soil boring was stockpiled at the site using a base <br />' and cover of plastic sheeting Proper disposition of the waste soil is currently pending Equipment <br /> rInsate water and purged groundwater were stored on-site in 55-gallon drums pending waste <br /> profiling and proper disposition <br /> The groundwater-grab sample and each of the selected soil samples were analyzed for TPH-as- <br /> gasoline, BTEX, MTBE, DIPE, ETBE, TAME, TBA, and 1,2-Dichloroethane (1,2-DCA) by EPA <br /> Method 8260B The sod samples collected at 15, 25 and 35 feet bgs were also analyzed for total <br />' lead by EPA Method 6010 <br /> 0 8 <br />
