2 . Source of Water Supply <br />The City of Ramsey is underlain by two aquifers, the Ironton -Galesville and the Mount <br />Simon -Hinckley formations. The City's wells are currently located in the Ironton -Galesville <br />formation, which is located above the Mount Simon -Hinckley formation. Wells in the Ironton - <br />Galesville formation are currently producing between 210 and 1450 gpm. <br />A summary of the specific well construction is presented in Table 1.5. <br />TABLE 1.5 <br />CITY OF RAMSEY, MINNESOTA <br />WELL CONSTRUCTION SUMMARY <br />City Well No. <br />1 <br />2 <br />3 <br />4 <br />5 <br />Unique Well No. <br />161441 <br />416183 <br />580303 <br />580313 <br />593672 <br />Year Installed <br />1984 <br />1987 <br />1997 <br />1998 <br />2000 <br />Capacity <br />970 gpm <br />220 gpm <br />1450 gpm <br />850 gpm <br />850 gpm <br />Casing (in)/Depth (ft) <br />14in/243ft <br />14in/240ft <br />24in/222ft <br />24in/191 ft <br />24in/210 ft <br />Total Depth <br />448 ft <br />320 ft <br />345 ft <br />321 ft <br />316 ft <br />3. Adequacy of Existing System <br />Currently, the existing Ramsey water supply system is in need of expansion to meet <br />current and future water demands. If the City continues to plan on utilizing groundwater sources, <br />a substantial number of wells will be required. Table 1.6 provides a summary of the wells which <br />would be required. Currently, three new wells are planned in the western well field. Minnesota <br />Department of Natural Resources staff have indicated that future well construction will need to <br />be coordinated with the overall water use of the area, and the pressure put on the Ironton - <br />Galesville aquifer to meet the region's water demands. Consideration of use of surface water <br />sources, such as the Mississippi River, will need to be addressed. <br />City of Ramsey, Minnesota — M21.34343 Page 1-3 <br />Water Emergency and Conservation Plan Prepared by Bolton & Menk, Inc. <br />
