Mr Michael Walton . • <br /> Walton Engineering <br /> March 20, 1998 <br /> A total of six soil samples were collected from beneath the former fuel dispenser islands (Figure 2) <br /> Additionally, one soil sample was collected from beneath a forrrler underground product pipeline <br /> (Figure 2) These soil samples were collected in situ at depths ranging from 3 to 4 feet below ground <br /> surface using the AMS core sampler immediately following the removal of overburden material <br /> Each individual sample sleeve containing a soil sample was sealed with plastic end caps labeled <br /> with the project and sample identification numbers and date and placed in iced storage immediately <br /> following sample collection The soil samples were delivered to the environmental laboratory,while <br /> adhering to the required chain of custody procedures (Appendix A) <br /> Soil Stockpile Sample Collection <br /> Soil and backfill material removed from the open excavation during the tank removal operation was <br /> stockpiled on asphaltic-concrete near the southwestern comer of the site Grayland collected a total <br /> of four soil sample composites from the soil stockpile Each individual soil sample was collected <br /> using the percussion core sampler by first removing approximately I foot of soil/backfill material <br /> from the surface of the pile and then driving a clean stainless steel sleeve into the freshly exposed <br /> surface of the pile A total of four individual soil samples (representing one soil sample composite) <br /> were collected from every approximated 100 cubic yards of soil material (Figure 2) The individual <br /> soil samples were handled in the same manner as described above Each set of four individual soil <br /> samples were composited by the laboratory into one soil sample for analytical testing <br /> �t Overexchvation Soil Sample Collection <br /> Because it was apparent that native soil situated mainly beneath the northern end of former <br /> underground storage tank T1 was contaminated with fuel hydrocarbons, the northwestern corner of <br /> the open excavation was deepened to approximately 24 feet below ground surface Soil samples <br /> were collected by Grayland on November 26, 1997, from the two exterior sidewalls and base of the <br /> overexcavated area(Figure 3) The soil samples were collected from the bucket of the excavator and <br /> handled in the same manner as described above The soil samples were delivered to the <br /> environmental laboratory for analytical testing, while adhering to the required chain of custody <br /> procedures (Appendix B) <br /> Abandoned Pipeline Soil Sample Collection <br /> Grayland returned to the site on December 2. 1997, to collect soil samples from beneath an <br /> abandoned underground product pipeline, which apparently was used to deliver fuel to the fuel <br /> dispenser islands situated formerly along Alpine Avenue Four holes were cut in the asphaltic- <br /> concrete at approximate 20-foot intervals along the abandoned pipeline (PL2 thru PL5 on Figure 2) <br /> A hand-auger was used to excavate soil in each hole to approximately 3 to 4 feet below ground <br /> surface A soil sample was collected from the base of each auger Bole using the percussion core <br /> sampler attached to a steel extender rod Each soil sample was retrieved and was handled in the <br /> same manner as described above The soil samples were delivered to the environmental laboratory <br /> for analytical testing while adhering to the required chain of custody procedures (Appendix B) <br /> GRA YLAND ENVIRONiVENTAL <br /> Gratila"d 023-160 trr 3 <br />
