The Problem…
• There are places in Minnesota where we are not achieving sustainability of our groundwater resources and “we” are currently making decisions with a lack of information
• Key Risks– Over use– Contamination
Minnesota’s Drinking Water Sources
Surface Water1.3 million
Private Wells1.2 million
Municipal Groundwater2.7 million people
75 % from groundwater; drought plan for surface water = groundwater
• “I didn’t think it was possible to run out of water in the land of 10,000 lakes. We’ve never had any problem before in the 14 years I’ve lived here," Mackay said, adding that at least four of her neighbors have had wells run dry in recent weeks.
