Soil samples were screened in the field with a PID,and a total of eight <br /> soil samples were collected at or above the water table. The field screening results of the sol! samples <br /> collected indicated that the eoncentradornfi of volatile organics lunged from below the PID't;limit of detection <br /> 120 <br /> to parts�'. pa per trillion(ppm). Table 2 presents the results of the field s.-icening. Two of the eight soil <br /> samples were selected for chemical analyses, and the remaining six sail sarr;ples were archived at the <br /> laboratory in the event additional testing was warrantee. <br /> PHIGOt.BP <br />
