Protection Agency (U.S. EPA) method 8010 for halogenated volatile organic compounds (HVOCs); and, • Prepare a letter report of the findings. ASSESSMENT ACTIVITIES SAMPLE LOCATIONS Three hand auger sample locations were selected prior to conducting field work. The boring locations are shown on Figure 2 - Sample Location Map,and photographs of sampling activities are provided at the end of this report. The borings were positioned based on the following criteria. • Position the borings in areas where PCE is handled or transferred, and where a material suspected of being waste PCE was observed. • Avoid potential subsurface utilities (if possible). SOIL SAMPLING Three soil borings (SB-1, SB-2, and SB-3)were installed inside, and immediately outside the rear door, of the Property building (Figure 2) using a hand auger and a hand held soil sampler. Fond-lel d Sanpl er CalWest Drilling of Manteca, California was contracted to Assenbl y core two 4-inch diameter holes through the concrete floor of the Property building, and one 4-inch diameter hole through the asphalt-covered parking area outside the rear door of the Property building. The three borings were expected to extend to a depth of five feet beneath ground surface (bgs); however, subsurface soil conditions inhibited augering beyond a depth 10-Fb a s l de 1 iN A of approximately 2 '/2 feet below ground surface.
