• operation of the former paint spray booth or storage of hazardous materials impacted <br /> shallow soils. <br /> Combined Support Maintenance Shop (CSMS) <br /> • Soil and soil gas samples were collected at the former location of a 2,000-gallon sump <br /> removed from the northeast side of the CSMS building in 1987 (B6 on Figure 4). The <br /> purpose of this sampling was to assess if residual contamination is present beneath the <br /> former sump location. <br /> • Soil and soil gas samples were collected adjacent to the washrack located inside the north <br /> wall of the CSMS building (B7) and adjacent to the associated clarifier (B8). <br /> • Soil samples were collected adjacent to one of the two abandoned hydraulic lifts located <br /> in the CSMS buildings (B9). Note, soil boring B7 is near the other hydraulic lift. <br /> • Soil and soil gas samples were collected in the former temporary storage area for waste <br /> oil/anti-freeze/solvents (B 10). The wastes were stored in two 400-gallon ASTs located in <br /> the vehicle storage area east of the CSMS. <br /> • One soil sample was collected at the former location of sand-blasting operations (B 11) in <br /> the southeast corner of the CSMS facility. The sampling was conducted to assess if near <br /> • surface soils are impacted by metals. <br /> • Soil and soil gas samples were collected from a location (B 12) adjacent to the former <br /> paint spray room at the CSMS. <br /> • One soil sample was collected from the battery storage and maintenance room at the <br /> CSMS (B 13). The sampling was conducted to assess if the soil is highly acidic or <br /> contains elevated lead concentrations. <br /> • Collect soil and soil gas samples from a location between two new hazardous material <br /> storage sheds north of Building 3 (B 14). One soil and one soil gas sample will be <br /> submitted for laboratory analysis. The purpose of this sampling is to assess if residual <br /> contamination may be present from historical undocumented hazardous material spills. <br /> • Soil and soil gas samples were collected from 11 locations (B 15a through B 18b) at 100- <br /> foot intervals along the ditch area. Surface samples were collected midway between the <br /> base of the ditch and the crest. Surface soil samples were composited in groups of up to <br /> three and submitted for laboratory analysis. Subsurface soil samples were also <br /> composited in groups of three prior to analysis. The sampling was conducted to assess if <br /> the soil has been impacted by petroleum hydrocarbons, solvents, and metals. <br /> • <br /> 2187-01/3134-100/MAY26'00 6 <br />
