January 6, 2020 <br />Page 4 <br /> <br /> <br /> <br />These particle tracking and capture simulations demonstrate the usefulness of a new <br />extraction well in C Zone for improving capture efficiency of contaminated groundwater in <br />the SHAD-007 & -008 areas, particularly for TCE identified offsite in the C Zone. Both <br />alternative locations presented in this memorandum are shown to capture TCE in this area, <br />but Alternative 2 may provide a more comprehensive capture zone for offsite TCE. This <br />improved capture would likely be associated with improved contaminant mass removal <br />and associated improvements in cleanup time. The results of this capture zone analysis are <br />subject to the same assumptions and limitations documented in the model update <br />appendix presented in the FFA Annual Progress Report. <br /> <br />Please let me know if you have any questions. <br /> <br />Sincerely, <br /> Sean Culkin, PG, CHG <br />Project Manager <br /> <br />
