Available options to meet water demand: 1. Conservation 2.Groundwater sources 3. Stormwater reuse 4.Surface water sources 5. Enhanced recharge 6. Reclaimed wasterwater The following should be addressed as water plans are updated: • Potential for water use conflicts and well interference - Due to the pervasiveness of private wells in the metro area, there exists a potential water use conflict and well interference of all appropriators • Potential for significant decline in aquifer water levels - A nearby DNR observation well documents a declining trend in aquifer water levels • Potential for impacts of groundwater pumping on surface water features and ecosystems - A state -designated trout stream is located within 5 miles of the community - Surface waters in the community may be directly connected to regional groundwater system - A spring has been mapped in or nearby the community • Significant vulnerability to contamination - A sinkhole (karst) has been mapped in or nearby the community - A vulnerable Drinking Water Supply Management Area has been designated within the community - A Special Well and Boring Construction Area has been designated within the community - Travel time from land surface to bedrock aquifers is estimated to be less than 50 years • Significant uncertainty about aquifer productivity and extent - Parts of the community may not be represented by a Minnesota Department of Health aqui- fer test - The county geologic atlas is more than twenty years old - Parts of the community may not be represented by a Minnesota Department of Natural Re- sources observation well • Regulatory considerations - A Groundwater Management Area has been designated within the community The Metropolitan Council's Local Planning Handbook contains interactive maps of all of these issues, and they are also summarized in Chapter 5 of this Master Water Supply Plan. The following actions are recommended: • Acknowledge the issues above in local water suppy plans and water appropriation permit applica- tions, including a plan to monitor. • Explore and support water demand (water conservation) programs such as incentives, ordinances, education and outreach, rates and other approaches. The Metropoliatn Council Water Conserva- tion Toolbox can support these efforts. • Before requesting water appropriations, water users in this areas should evaluate the need to ad- dress water conflict and well interference including a) an inventory of all active domestic and public WATER SUPPLY MASTER WATER SUPPLY PROFILES PLAN- Draft June 2015
