OVM field screening of <br /> the soil samples collected from borings SB-1 through S13-4 detected positive readings <br /> ranging between 2 and 9 parts per million by volume (ppmv) at S13-1, 5 to 10 ppmv at <br /> S13-2, 0 to 25 ppmv at S13-3 and 5 to 18 ppmv at S13-4. <br /> Chemicals were not detected in the four groundwater samples with the exception of the <br /> groundwater sample from S13-1. MTBE and xylenes were detected in groundwater at <br /> P:\PROJECTS\Safeway\L284\Stockton-103\1769—Pre-Gas_Rptdoc <br />
