Wetland Delineation report shows wetlands in the vicinity of the RTC site disappearing <br />during the mid to late 1980's which is prior to the development of the municipal wells. <br />This same phenomenon occurs again in the mid to late 1990's and prior to the installation <br />of Wells 4 and 5. The evaluation also found, as stated earlier, that drawdown levels in the <br />FIG unit are minimal and, therefore, could not be influencing the wetlands. To verify <br />these finding, however, it is recommended that long term monitoring be performed. <br />There is also some concern that increased pumping in the FIG aquifer could impact private wells <br />that pump from this aquifer. Again, the residual drawdown levels in the FIG average 5- to 10-feet <br />during the peak summer pumping period (Appendix F) and recover fully during the Fall, Winter <br />and Spring. Therefore, the radius of influence of the wells will be very small meaning there could <br />be no impacts to private wells developed in the same unit. <br />Before additional wells are constructed, additional appropriations will be applied for through the <br />DNR. This will most likely require both short- and long-term testing and monitoring to verify the <br />above findings. Through this process, the City can insure that there continue to be no impacts on <br />groundwater and surface resources due to their appropriations from the FIG. <br />13-9 <br />
