Additional fieldwork at the three above-mentioned SWMUs will include test-pit, auger boring, and surface soil sampling unexploded ordnance UXO surveys and mapping of visual observations of propellant, UXO, and debris. The additional work is designed to supplement existing data at each SWMU to further define the vertical and horizontal extent of contamination and to assess potential risks to human health and the environment associated with this contamination. The proposed work at each SWMU is discussed in the following scope of work and summarized in Table 1. The proposed work includes the following 1. Surface and subsurface soil sampling for dioxinsfurans and sediment sampling for metals and explosives at SWMU 6 2. Surface and subsurface soil sampling of the overshot area behind the second bullet stop at SWMU 8 for metals 3. Mapping of the distribution of propellant, debris, and UXO at SWMU 40, excavation and sampling of test pits where the previous explosives data results were rejected, and sampling and analysis of soils located beneath fragments of propellant material. Analytical parameters for this investigation are listed in Table 2, including the laboratory methods and CRLs andor method detection limits, as appropriate. One-hundred percent data validation will be performed on all methods or individual analytes that are not USAEC performance-demonstrated. All analyses that are performed by USAEC methods and have established CRLs will have 20 percent data validation performed beyond the computerized validation conducted by the IRDMIS computer system.
