Soil Stockpiles Assessment Status <br /> Approximately 1,500 to 2,000 cubic yards of soil are stockpiled near the former bum pits. <br /> 1 Appendix B shows a sketch prepared by SSSE apparently identifying the bum pit or teepee source <br /> for the different areas of the stockpiles.Due to the low quality of the much-duplicated drawing,AGE <br /> has remarked a second copy for greater clarity. <br /> ' Figure 8 shows the current distribution of the 1,500 to 2,000 cubic ds of stockpiled soil. The <br /> stockpiled soil ranges in color from grey to reddish orange and contains abundant debris, such as <br /> 1 burned organic and plastic material, scrap metal, glass, burned or partially burned wood, concrete, <br /> brick, cobbles and gravel. <br /> 1 In 1999 and 2000, AGE sampled the soil piles excavated from the former burn pits for laboratory <br /> analysis to characterize the soil for disposal purposes. Figure 8 shows the sampling localities and <br /> distribution of the soil stockpiles. Composite samples have been analyzed for CAM 17 metals,pH, <br /> 1 TPH-d(diesel),TPH-mo (motor oil), TRPH, and dioxins. Selected sam les were also analyzed for <br /> herbicides and pesticides. <br /> 1 Selected samples or composite samples with elevated total concentrations of detected metal analytes <br /> 1 exceeding the soluble threshold limit concentrations multiplied by 10 were analyzed for the soluble <br /> metals concentrations. Lead, barium and chromium had total concentrations that created potential <br /> concern for soluble metals. <br /> 1 The composite soil samples were made up of samples collected from tb a same or similar soil piles <br /> as shown below; the layout of the soil stockpiles used for composing is shown on Figure 8: <br /> 1 Composite No. 1 = SP1-3 + SP2-1 + SP24 + SP3-2 + S P3-6 <br /> Composite No. 2= SP4-3 + SP5-1 + SP54 + SP6-3 + P7-3 <br /> 1 Composite No. 3 = SP9-1 + SP9-3 + SP11-1 + SP 11-3 <br /> Composite No. 4 = SP8-1 + SP8-2 + SP10-1 + SP10-3 <br /> Composite No. 5 = SP12-1 + SP12-3 + SP15-1 + SP 15-2 <br /> 1 Composite No. 6 = SP13-1 + SP 13-3 + SP14-1 + SP14-3 <br /> Composite No. 7 =SP 16-1 + SP 19-2+ SP 19-4 <br /> Composite No. 8 = SP 17-2 + SP 18-2+ SP20-1 <br /> ' Total lead, barium and chromium concentrations in various composite samples were high enough <br /> 1 to trigger analysis of the samples for the soluble forms of the metals; c my total lead in composite <br /> Advanced GeoEnvironmental,Inc. <br /> 1 <br />
