Both soil 'grid groundwater were <br /> sampled and analyzed to determine if a signific <br /> this site. ant release of petroleum has occurred at <br /> �1 <br /> 2.0 SCOPE OF WORK <br /> Two borings to obtain laboratorysoil and <br /> groundwater samples were completed on <br /> November 4, 1996, to evaluate possible contamination fora property transaction at this <br /> site. The borings were located near the fill pipes and fuel purrs and were drilled to <br /> groundwater, approximately 42 feet from the surface (Figure 2). Soil samples were <br /> collected at five foot intervals for screeningof a dontamination an <br /> apparent pp d geological <br /> information. Two laboratory soil samples and a water samplewere obtained from each <br /> ' boring. Water samples, for screening purposes, were obtained through the hollow stem <br /> auger while still inserted in the bore hole. <br /> Soil samples obtained from Boring B-1, at 22 and 37 feet in!depth, were both non-detect <br /> for the compounds analyzed. No apparent contamination (odor or staining) was observed <br /> during the drilling and sampling of this boring. The groundwater sample, B-1-45' Water <br /> (H20), did not exhibit apparent petroleum contaminants, such as siheen or odor, but did <br /> contain Toluene at a barely detetectable concentration. <br /> Soil Boring B-2 encountered significant apparent petroleum contamination from the <br /> surface to five feet in depth. The odor and discoloration began to diminish below five feet <br /> to a depth of 10 feet and was not observable below 12 feet hn depth. A <br /> ep laboratory soil <br /> sample was obtained at 22 feet and was non-detect for the:compounds analyzed. The <br /> second laboratory soil sample from this boring was obtainedwithi l the capillary zone at <br /> 40 feet. It contained Xylenes at 5.3 pg/Kg, slightly above detection limits- The <br /> groundwater sample, B-2-45' Water, contained low concentrations of Gasoline, BTEX <br /> and M,ME (Methyl tert Butyl Ether). <br /> i <br />
