• One soil boring (B10b) was advanced at the forrnei boring location, B10, near the waste stoiage <br /> area Soil samples were collected just beneath the pavement section, and at 5 feet bgs The <br /> samples were tested for TPH-g, d, mo, BTEX, and SVOCs <br /> At the former sandblasting area, boring location B11, one soil sample was collected just beneath <br /> the pavement section and analyzed for 17 heavy metals (CAM 17) <br /> The pavement upwelling areas were excavated to deterinme the cause At each of three <br /> upwelling areas, a bluish white crystalline powder was identified Samples of the powder were <br /> collected and analyzed foi hazardous constituents Excavated soils were i eplaced in the <br /> excavation pending char actenzation for disposal <br /> 2.6 3 OMS <br /> Areas of concern at the OMS comprise the former vehicle fueling station in the parking lot <br /> between the OMS and CSMS, and the vehicle inspection lack south of the OMS building <br /> Elevated concentiations of petroleum hydiocaibons were detected at depths to 25 feet at the <br /> fbimei vehicle fueling station, and to 10 feet bgs at the vehicle inspection lack, in March 2002 <br /> Figure 4 shows the layout and boring locations at OMS <br /> Three soil borings (B30 through 1332) Nveie advanced adjacent to the forixier location of a 10 000- <br /> gallon diesel UST and 5,000-gallon gasoline UST removed from the area southeast of the OMS <br /> The borings were advanced to depths of 45 to 48 feet A total of eight soil samples and tluee <br /> grab-giound-water samples (one from each boring) were collected from the borings The soil and <br /> groundwater samples weie analyzed fol. TPH-g, TPH-d, TPH-j, BTEX and five fuel oxygenates <br /> Two soil borings (B33 and B34) were advanced adjacent to the vehicle inspection rack located <br /> south of the OMS building The borings were advanced to a depth of 48 feet A total of eight <br /> soil samples and two grab groundwater samples (one from each boring) were collected from the <br /> borings The soil and gioundwater samples were analyzed for TPH-g, TPH-d, TPH-j, BTEX and <br /> five fuel oxygenates <br /> 104700 4766 230/08SEPT2004 7 <br />
