The sample sealing technique consiRstod of capping <br /> the brass tube with aluminum foil., plastic end cap F; and a final <br /> seal of elastic tape. The previously sealed sample from the five <br /> foot depth at location MCW �1 was discarded. <br /> Following the collection of sample MCW 11, the auger and tube <br /> driver were thoroughly decontaminated utilizing a potable <br /> water/laboratory reagent soap mixture wash followed by a potable <br /> water rinse and a deionized water final rinso. <br /> rhe next location sampled was MCW 02. This location is between the <br /> central tank and the so,.ithern most tank (T2 and T3) . An with <br /> location MCW 11, sampled were collected at depths of five feet and <br /> nine feet PGS. The five foot depth sample from MCW #2 was labeled <br /> MCW 02-5 and the nine foot depth sample was labeled MCW 02. Doth <br /> of these samples were field screened, sealed, labeled and stored on <br /> ice. <br /> Attempts were made to sample several other locations in the <br /> vicinity of the three tanks, but to no avail. Auger rejection <br /> occurred at depths of two to three feet BGS at three alternative <br /> locations near the tanks. Therefore, the derision was made to }seep <br /> the five foot depth sample from location MCW X92 for analysis. <br /> Next, the area around t:hF fuel distribution pipelinrsl, was sampled. <br /> Two locations (PL 91 and PL 12 as shown on Figure 1) were selected. <br /> Location PL 01 was sampled first. Again, prior to sampling, the <br /> auger was thoroughly decontaminated as explained previously. <br /> r Borehole PL 11 was advanced to a depth of eight feet BGS with the <br /> hand auger. sample PL #1 was collected at this depth, field <br /> screened, sealed, labeled and stored on ice. Borehole Pi 12 was <br /> advanced to a depth of five feet, at which depth the auger could <br /> not be advanced further. Sample PL #2 was collected from this <br /> depth. <br /> Finally, a sample was collected from the fuel dispenser island <br /> area. open dirt existed beneath a coverplate near an overhead <br /> structure support pole. This coverplate was installed to allow for <br /> access to the lighting electrical conduit which rises from below <br /> gr4?a at that point. The borehole at this location could only be <br /> advanced 1.3 feet BGS. sample FL was collected from that depth. <br /> once completed, the samples were stored in a refrigerated <br /> environment over night for delivery to the analytical laboratory <br /> the following morning. Appropriate chain of custody documents <br /> accompanied the sample delivery. The sample chain of castody <br /> record is enclosed with the analytical results In Appendix A. .All <br /> PID-readings-forthe field screened nampins are listed in Table 1. <br /> 3 <br />
