!�- <br /> I <br /> 12 February 2004 <br /> AGE-NC Project No 00-0769 <br /> Page 7 of 7 <br /> 1,2-DCA and BTEX compounds were present above the DHS's Maximum Contaminant <br /> k <br /> Levels (MCLs) in all levels of the multi-level well MW-4 No MTBE was detected in any <br /> samples from this monitoring event <br /> • The lateral extent of the dissolved 1,2-DCA appears to be near site and directly east of the <br /> LL site in the first hydrologic unit The vertical extent of dissolved 1,2-DCA is poorly`defined ' <br /> off-site <br /> • In general,the lateral and vertical extent ofhydrocarbon-impacted ground water has not been <br /> delineated <br /> 5.0. RECOMMENDATIONS <br /> f - f <br /> Based on this and previous site investigations, AGE recommends ; <br /> , <br /> • Continued quarterly monitoring of the well network The next monitoring event should be <br /> scheduled for March 2004 <br /> • Conduct additional contaminant assessment east of the current monitoring well network, <br /> Iutilizing grab ground water sampling for potential monitonng well placement <br /> o Ground water monitoring wells should be re-surveyed by a state-licensed surveyor <br /> I r <br /> 6.0.
