0971c*-3 During the soil boring operation, soil samples will be collected using a Standard Penetration Sampler. Soil samples will be retained by Woodward-Clyde Consultants (WCC) for future analysis should the need arise. The samples will be examined by a geologist for stratigraphic control. Each boring will be fitted with a monitoring well, and after well development, groundwater samples will be collected and analyzed for pH and heavy metals. The heavy metals include copper, nickel, tin and lead. We do not propose to do any analysis for priority pollutants because the manufacturing process suspected of being the contamination source does not use these materials. 2.2 Phase II A. The scope of the second phase of the sampling plan is contingent upon the results of the first phase. If Phase I establishes that contamination has not moved off site, we propose to advance a minimum of 8 borings through the floor in the interior of the building. The approximate locations of these borings are shown on Figure 3. Their precise location will be determined in the field and will depend upon the location of reinforcing steel in the floor and underlying utility conduits. The borings will be advanced to three feet below static groundwater and fitted with monitoring wells. These wells are to be considered temporary and will be abandoned when no longer required. Being located inside the building, the monitoring wells will not require the use of protective Christy boxes. Soil samples will be collected at three foot intervals by using a Standard Penetration Sampler. Soil samples will be analyzed for pH, copper, lead, nickel and tin. We may recommend the installation of an additional two wells if conditions at the annex require it. This decision will be made in the field. The exact location of the wells will be determined at that time.
