McDowell &Davis Towing <br /> Phase 11 Groundwater Monitoring Well Installation Report <br /> depth laboratory soil samples were collected every five feet including the bottom of this <br /> baring. All soil samples were reported as "non-detect for the compounds analyzed" by <br /> the analytical laboratory. Traces of gasoline and BTEX were present in the groundwater <br /> sample but none of the Oxygenated Compounds were detected. <br /> Boring MW-2 was drilled in the suspected up gradient direction. However, this study <br /> showed MW — 2 is actually down gradient of-the of the dispenser islands between the <br /> former tank pit and the islands near former soil boring B-1. The boring was drilled to 70 <br /> feet in depth with no odor or soil discoloration encountered. Beginning at 50 feet in <br /> ` depth laboratory soil samples were collected every five feet including the bottom of this <br /> boring. All soil samples were reported as "non-detect for the compounds analyzed" by <br /> L the analytical laboratory. Traces of gasoline and BTEX were present in the groundwater <br /> sample but none of the Oxygenated Compounds were detected. <br /> 4 Boring MW-3 was drilled in the suspected down gradient direction of the tank pit near <br /> former soil boring B-4. However, MW — 3 is actually the furthest up gradient well <br /> currently at the site. This boring was drilled to 70 feet in depth with no odor or soil <br /> �. discoloration encountered. Beginning at 35 feet in depth additional laboratory soil <br /> samples were collected at 55, 60, 65 and 70 feet. All soil samples were reported as "non- <br /> detect for the compounds analyzed" by the analytical laboratory. Traces of gasoline and <br /> BTEX were present in the groundwater sample but none of the Oxygenated Compounds <br /> were detected. <br /> ,.� <br /> Laboratory Soil Sample Results 11-21&22-2000 <br /> Sample I.D. j Gasoline Benzene I Toluene E-Benzene Xylenes MTBE 7 8260 <br /> MW-1-50' ND ND ND ND ND ND NA <br /> MW-1-55' ND ND ND ND ND ND NA <br /> MW-1-60' ND ND ND ND ND ND NA <br /> MW-1-65' ND ND ND ND ND ND NA <br /> MW-1-70' ND ND ND ND ND ND NA <br /> MW-2-50' ND ND ND ND ND ND NA <br /> MW-2-55' ND ND ND ND ND ND NA <br /> MW-2-60' ND ND ND ND ND ND NA <br /> c..
