2.0 PURPOSE AND SCOPE OF WORK <br />The purpose of the Baseline Investigation was to document baseline environmental conditions in <br />soil and groundwater at the site for comparison to future environmental conditions. The scope of work <br />consisted of the following four tasks: <br />TASK 1 - Surface Soil pH Evaluation; <br />TASK 2 - Subsurface Soil Investigation; <br />TASK 3 - Groundwater Investigation; and <br />TASK 4 - Site Investigation Reports. <br />Each of these tasks is described in more detail below. <br />Task 1 - Surface Soil pH Evaluation <br />This task is specific to Parcels I and II and consisted of evaluating the pH of soils in former coal <br />stockpile areas. This task is not be discussed in this report. <br />Task 2 - Subsurface Soil Investigation <br />This task consisted of evaluating soil from specific areas of the three parcels. Soil samples were <br />collected from hand augured borings and from soil borings advanced for monitoring well installations. <br />Hand auger borings specific to Parcel III were located in the following areas: <br />Near the center of the former copper concentrate stockpile (B-3); and <br />Under the point of worse case observed spillage from each of the four conveyors (B-4 <br />through B-7). <br />Soil borings and monitoring wells specific to Parcel III are illustrated in Figure 2. <br />The locations of the former stockpiles and points of worse case observed spillage were discussed <br />with DBT representatives prior to the advancement of the borings. From each of the hand auger borings, <br />two relatively undisturbed soil samples were collected when conditions were adequate. Target sample <br />depths included near the ground surface (0 to 6 inches below ground surface (bgs)), and from the <br />capillary fringe (approximately 10 feet bgs). Soil samples were analyzed by a California certified <br />laboratory for the following constituents: <br />SAC28.013 <br />December 20, 1991 <br />2 <br />DAMES ,S7. MOOR F
