What is groundwater sustainability?
Much of Minnesota is naturally endowed with good supplies of groundwater. However, those supplies are not evenly distributed in the state nor are they limitless. Overpumping of the system causes continued declines of groundwater levels in aquifers, local impacts on streams and wetlands, and the potential that needed groundwater resources would not be available for future use. Groundwater withdrawal that results in unacceptable impacts on the resource is not sustainable.
Sustainable use of groundwater 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 groundwater 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 groundwater management and sustainability.
Statement of Issues and Needs
A short statement of current issues and needs related to ground water management and sustainability, summarizing information in a series of fact sheets that provide a closer look at specific issues.
Statement of Issues and Needs June 2005
The following fact sheets were prepared as background to the "Statement of Issues and Needs". Additional facts sheets will be included on this list as they are finalized.
- Where is ground water and is it available for use? June 2005
Ground water is everywhere beneath Minnesota's land surface, but it is not necessarily available for use everywhere. This fact sheet describes the six ground water areas in Minnesota and the general availability of ground water in those areas.
- Ground water and surface water - the vital connection June 2005
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.
- Options for sustainable management of ground water June 2005
Sustainable ground-water use will require managing a limited resource. This fact sheet describes several management approaches.
- Moorhead balances uses of surface water and ground water June 2005
The City of Moorhead, Minnesota, operates a regional water supply system that relies on both surface water and ground water. This fact sheet illustrates how the City's conjunctive use of water resources must be managed for both quantity and quality to assure long-term adequate supply.
- Water conservation: wise use and efficiency is everyone's responsibility June 2005
Conservation of available water supplies and more efficient use will be increasingly important in the future. This fact sheet describes how all water users can have a role in this effort. What we throw away today may be one source of our water sustainability in the future.
