The TAT PA indicated that white asbestos-like debris was visible at many areas of the <br /> site. A pile of asbestos debris 200 feet x 2 feet wide x 1 foot high was also identified in the <br /> TAT report, and is marked on Figure 4. Off-site soil samples were taken in the cultivated <br /> lands immediately surrounding the site in order to determine whether any gross off-site <br /> migration had occurred. The soil borings (Figure 4: A-G) were conducted to determine <br /> the vertical extent of contamination by visual examination of the soil cores. Visible <br /> asbestos debris within the soil matrix was observed to depths of between 2 and 4 feet <br /> below grade. Samples were analyzed via polarized light microscopy (3)• <br /> 3.2.2 Discussion of Sample Results <br /> The sample results confirmed the widespread surface and subsurface contamination of <br /> the site with asbestos-containing debris. <br /> Table 1 <br /> On-Site Soil Sample Results - French Camp Site <br /> Sainp Loc on Resu t <br /> 1-1 rysoti a Asbestos <br /> 1-2 0-70 Z rysoti a As estos <br /> U-3 4U-Wu/0 Chrysotile 3-5% Crocidolite <br /> III_ <1% C rysoti e As estos <br /> 040° C rysoti a As estos <br /> Table 2 <br /> Off-Site Soil Sample Results - French Camp Site <br /> Same L"- ation Result <br /> 1-2% C rysoti a Asbestos <br /> 7 <10/6 Chrysotile Asbestos <br /> 1-2% rysoti a As estos <br /> 9 <10A Chrysotile Asbestos_ <br /> Surface and subsurface composite samples show chrysotile asbestos contamination of up <br /> to 60-70 percent.
