7_Ma.=n_Q PYKE*1122 _ Pcnac COM. inserted into a plastic Zip-Lock bag and then placed into an ice chest for transport back to the laboratory. The chain-of-custody was similarly designated and included date and time the sample was collected (See Appendhi 9 f®rr Daborat®ryy data sheeft). The soil samples were selected at specific vertical intervals based on the location of the capillary fringe, at significant changes in lithology, and/or at contact with noticeable hydrocarbon contamination. The sampler was decontaminated before and rafter each use by rinsing with an Alconox solution wash and fresh tap water. All rinseate water was stored in a 55 gallon DOT approved drum. The drum wilB be properly Baabeled and stored onsite until sampling is authorized to establish ¢a legal point of disposal. 2.3 alrouG9QiwaQMV Sim& s aa'anp0iM0 Groundwater was encountered at ¢a depth �00 feet Bags and was sampled approximately 10 minutes later when the water level stabilized at a depth of 96.4 feet bgs. The groundwater grab sample was colleted with a steel check valve bailer and was stored in six 40 mi V®As. The borehole was not converted to a groundwater monitoring wel0 because PID readings were non-detectaaMe from soil samples collected from 74 to 9 00 feet bgs. The boreha0es were properly backfilled with a Type 0-00 cement grow. �. :3.0 dAMG° &`OO R7 R12 SUILU S 3.9 CGc�soB6r�e O��eaawtes Mo gaaso0ine on ygevnWes were identified) in the sixteen (�6) soi0 sampBes and one groundwater grab sample collected and aanaa0yzed (SGa &ppendhz 2 for Ucu borax orry data sheets). 3.2 Gaso0ine (TPMO) in 50n0 and Groundwaftr Concentrations of TPHg increased with depth from 22 feet bgs to 40 feet bgs to from a range of 2.7 ppm to 3,300 ppm. At 45 feet bgs to concentrations decreased to 55 ppm to non-detectable levels identified at 50, 59, & 63 feet bgs. Samples collected and analyzed for TPHg, from 70 to 100 feet bgs, yielded non-detectable results for leachability. This indicates that the TPHg is not leachable to the groundwater. TPHg was identified in the groundwater grab sample, at 210 ppb, indicating that the benzene reached the groundwater by leaching through the vertical soil profile via another migratory pathway or by cross contamination of the bailer during its decent down the center of the hollow-stem auger.
