AGS <br /> into account the layout of the OWS system at the site and groundwater flow direction. <br /> Five of the seven borings (B41OA-2through B41 OA-6) are located in the immediate area <br /> of the Building 410A OWS system. These borings are positioned directly adjacent and <br /> downgradient of key components and/or locations of the OWS system. Two additional <br /> borings (B410A-1 , -7) are located at the upgradient and downgradient margins of the <br /> OWS site. Soil samples will only be collected for chemical analysis from the five <br /> borings located in the immediate area of the OWS system. These samples will enable <br /> characterization and delineation of maximum vadose zone chemical concentrations in <br /> the OWS area. Soil samples will not be collected for chemical analysis from the two <br /> other, up- and downgradient borings because of their distance from the immediate OWS <br /> area. Grab groundwater samples will be collected from all seven borings for <br /> characterization and delineation of potentially impacted groundwater. Table 1 lists all <br /> soil borings by OWS site and includes the purpose of each boring. <br /> Building 508 OWS. Seven soil borings are proposed to be completed at the Building <br /> 508 OWS site (Figure 5). The boring locations at the Building 508 OWS site take into <br /> account the layout of the OWS system at :he site and groundwater flow direction. Five <br /> of the seven borings (8508-2 through B508-6) are located in the immediate area of the <br /> Building 508 OWS system. These bcrings are positioned directly adjacent and <br /> downgradient of key components and/or iccaiicns of the OWS system. Two additional <br /> borings (B508-1, -7) are located at the upgradient and downgradient margins of the <br /> OWS site. Soil samples will only be collected for chemical analysis from the five <br /> borings located in the immediate area of the OWS system. These samples will enable <br /> characterization and delineation of maximum vadose zone chemical concentrations in <br /> the OWS area. Soil samples will not be collected for chemical analysis from the two <br /> other, up- and downgradient borings because of their distance from the immediate OWS <br /> area. Grab groundwater samples will be collected from ail seven borings for <br /> characterization and delineation of potentially impacted groundwater.
