<br />C1.6 Assessment of Data Elements <br />C1.6.1 Use of the Municipal Wells <br />Ramsey currently has eight municipal water supply wells in the municipal water supply and distribution <br />system for Public Water Supply 1020035. Locations of the wells are shown on Figure C-1and construction <br />details for the Ramsey municipal wells are summarized in Table C-1 . Copies of the MDH well records for <br />these wells are presented in Appendix A. <br />The 2010 census indicated that Ramsey had a population of 23,668. In 2017 the population of Ramsey was <br />estimated to be 25,581 and it was estimate that the water system served 13,270 people <br />33,350. <br />As discussed above, average day water demand in 2017 was 1.92 MGD and the projected 2030 <br />average day demand is 3.01 MGD (approximately 2,090 gpm) with a projected population served of <br />22,987. <br />For the period 20102017, daily demand on the Ramsey water system averaged about 1.7 MGD. Ramsey <br />currently has a permitted annual groundwater appropriation of 850 MGY. The permitted instantaneous <br />total pumping rate for the Ramsey system is 8,200 gpm. <br />Ramsey currently has three elevated water storage facilities. These facilities have a combined storage <br />capacity of 4.0 MG. Construction of additional water storage facilities is not currently planned (e.g., <br />Ramsey, 2018a). <br />C1.6.2 Wellhead Protection Area Criteria <br />Delineation of the WHPAs for the Ramsey wells was completed in 2018. Information/criteria used to <br />perform the WHPA/DWSMA delineations are discussed in the Part 1 WHPP amendment prepared by the <br />MDH (2018) and are summarized below. <br />C1.6.2.1 Time of Travel <br />A 10-year groundwater time of travel capture zone for each but it was <br />determined that capture zones for a 12-year time of travel would still be contained within the boundaries <br />of the DWSMAs previously delineated for the Ramsey wells (MDH, 2018). The individual capture zones <br />were combined into composite capture zones that were used to delineate the DWSMAs. The one-year <br />groundwater time of travel capture zones <br />C1.6.2.2 Aquifer Transmissivity <br />Transmissivity of the Tunnel City-Wonewoc aquifer <br />unchanged from that used in the previous (2007) delineations (MDH, 2018). <br /> <br /> <br /> C-11 <br /> <br /> <br />
