Sustainability of Minnesota's Ground Waters

What is ground water sustainability?

Much of Minnesota is naturally endowed with good supplies of ground water. However, those supplies are not evenly distributed in the state nor are they limitless. Overpumping of the system causes continued declines of ground water levels in aquifers, local impacts on streams and wetlands, and the potential that needed ground water resources would not be available for future use. Ground water withdrawal that results in unacceptable impacts on the resource is not sustainable.

Sustainable use of ground water is the use of water to provide for the needs of society, now and in the future, without unacceptable social, economic, or environmental consequences.

Sustainable use of water resources requires balancing the use of the resource among competing uses, including environmental uses. To assess the long-term viability of a particular ground-water use, it is necessary to consider both the technical aspects, such as the amount of water in circulation, as well as the desires of the community to accept or limit economic, social, and environmental impacts.

Using water in ways that minimize impacts on both ground water and surface water requires a comprehensive, long-term approach to water resources management that accounts for system interactions.

The following documents provide a short introduction to ground water management and sustainability.

    Minnesota's aquifers, streams, lakes, and wetlands are sustained by a balancing act between precipitation and these parts of the hydrologic system. This fact sheet discusses this balancing act and what happens when the balance is changed.
