'aIle soil samples were collected by advancing the boring to a point €mnleciiately above title sampling depth, curd then dr€ving a California-modified, split spoon sampler containing brass sleeves through rite lrollo�v steal of the auger into the relatively undisturbed soil. The sampler and brass sleeves ��ere steam-cleaned or washed thoroughly with .l laborator.; s;rade, non l�ltosphatic deter_ent and water before cacti use.

'aIle \lumber (J :!lows required to drive the sampler each successive 6 incites was counted and Iecorded to evalu'lic the relative consistenev of the soil. During drilling, the lo�-ist used ,t Field photoionization detector (PID) to characterize the relative hygeudrocarbons. Field instruments such as the PID are useful for indicating levels of f h relative levels of In,drocarbon \apors but do not detect the concentration oydrocarbons ision as iabot..tory analyses. Otte of the samples in brass sleeves present with the same prec not selected for laboratory analysis at each sampling interval was tested in the field using a IMP PID. 'I-his testing was performed by placing the intake probe of tile. PID against the soil after opening the brass cotltairter.
