Appendix F was prepared to <br />assess the general magnitude of the problem and the <br />solutions required to address the issue. It is now apparent <br />that the wetlands in question experience natural drying <br />during periods of relative low precipitation. The <br />photographic history included as part of the Wetland <br />Delineation report shows wetlands in the vicinity of the <br />COR site disappearing during the mid to late 1980's which <br />is prior to the development of the municipal wells. This <br />same phenomenon occurs again in the mid to late 1990's <br />and prior to the installation of Wells 4 and 5. The evaluation <br />also found, as stated earlier, that drawdown levels in the <br />FIG (Franconia Ironton -Galesville) unit are minimal and, <br />therefore, could not be influencing the wetlands. To verify <br />these finding, however, it is recommended that long term <br />monitoring be performed. <br />There is also some concern that increased pumping in the <br />FIG aquifer could impact private wells that pump from this <br />aquifer. Again, the residual drawdown levels in the FIG <br />average 5- to 10-feet during the peak summer pumping <br />m <br />G <br />G <br />November 2018 <br />Mitigation Plan Update - 2018 <br />00 <br />
