(Appendix F: Water Supply Adequacy Analysis, Water Supply Planning in the Twin Cities Metropolitan Area Technical Report, January 2007). Regardless of water resource adequacy projections — we believe that the city must address the emerging issue of sustainable water supply by monitoring water level trends to determine if municipal or regional withdrawal is negatively impacting supply. In its most recent water appropriations permit the city committed to increased cooperation with the DNR's Ground Water Level Monitoring Program and water conservation through education and applying increased water use pricing to discourage wasteful water users. By cooperating with the DNR the city is playing an active part in monitoring its water resources and managing its future water supply system. The plan should acknowledge the city's efforts. We recommend that the plan include the provisions of the city's water appropriation permit to cooperate with the Minnesota Department ofNatural Resources mission to monitor and maintain sustained water resources. - • The plan makes reference to a city Groundwater Protection Plan including. Policy 6.Protect the groundwater source from contamination by implementing the groundwater protection plan. (pg. 8 -3) Groundwater Protection: The city will implement the groundwater protection plan to protect the groundwater source from contamination. (pg. 8 -20) We believe that the "Groundwater Protection Plan" referenced in this plan is actually the city's Wellhead Protection Plan that addresses (in a sense) groundwater protection in discrete zones around the city's municipal wells. No references to the city's Wellhead Protection Plan or its goals are found in this plan. We recommend the plan be revised to replace references of a city groundwater protection plan with the city's wellhead protection plan. • The plan states: "In Lino Takes the Jordan Aquifer only exists beneath the southern section of the city. There is no suitable aquifer for a well in the northern part of the city." (page 8-4) The plan does not offer an explanation or reference documentation that supports this statement We disagree with the statement that there are no suitable aquifers for a well in northern Lino Lakes. The Minnesota Geological Survey map (M -104; Bedrock Geology and Structure of the Seven - County Twin Cities Metropolitan Area, Minnesota) indicates that the Franconia-Ironton- Galesville (FIG) and the deeper Mount Simon- Iimckley (Mts -I m) aquifers are found throughout the City, Anoka County, and the region. The FIG aquifer is used extensively where the Prairie du Chien - Jordan aquifer unit does not exist. . The city maintains an interconnection with the Minnesota Correctional Facility's water system (for emergency supply to the city) that draws water from the FIG and Mts -Hln aquifers. •
