Water availability and use
The Water Underground: Implications for Agriculture and Opportunities for Change covers sustainable use of groundwater through an agricultural lens. This third and final report in The Water Underground series makes recommendations for groundwater quantity and quality to manage shared resources.
The Water Underground: Stretching Supplies focuses on three approaches to building groundwater resilience by stretching local supplies: reducing use, reusing water before discarding it, and recharging supplies. This report — the second in a series of three planned for 2016-17 — examines the crossroads Minnesotans face with groundwater use — we are using groundwater faster than it is being replaced — and makes recommendations focused on proven methods to manage supplies.
The Water Underground: Reframing the Local Groundwater Picture is targeted at public water supply managers – the public works directors, council members, and mayors of those municipalities operating water supply systems. This report — the first in a series of three planned for 2016-17 — tackles head on which portions of the state and metropolitan area currently have long-term water supply issues. This eliminates a major flaw of previous reports; namely, most cities hear about declining groundwater levels and assume it doesn’t apply to them.

Published April 2013.
Draft Groundwater Management Plan. An October 2013 draft plan by the Minnesota DNR calling for major changes in the way the agency regulates and manages groundwater use. The strategy, prompted by significant new state funding for groundwater initiatives, calls for better enforcement of existing rules requiring permits for high-volume pumping. The plan sets a goal of ensuring that no aquifers are used depleted by unsustainable use and ensuring that groundwater pumping does not damage surface waters.

Nitrogen in Minnesota Surface Waters. A Minnesota Pollution Control Agency report on the estimated 306 million pounds of nitrogen that flow into Minnesota surface waters each year. The report looks at sources — more than 70 percent comes from agriculture — flow patterns — most reaches rivers and streams through farm tile drainage or the discharge of groundwater, and trends — concentrations in some watersheds seem to be improving and seem to be getting worse in others. Published in June 2013. Read the executive summary.
Minnesota Nutrient Reduction Strategy. A Minnesota Pollution Control Agency proposal for a phased effort to reduce the nitrogen and phosphorus, primarily from agriculture, that flow into Minnesota streams and then down the Mississippi River and the Red River to the Gulf of Mexico and Lake Winnipeg. The plan calls for reducing the nitrogen and phosphorus going to the Gulf by 35 percent and 20 percent, respectively, by 2025. The strategy was issued in draft form in October 2013. Read comments that the Freshwater Society submitted on the strategy.
Condition of Minnesota’s Groundwater. A Minnesota Pollution Control Agency analysis of groundwater monitoring conducted between 2007 and 2011. The report says nitrate concentrations have generally not changed in 15 years; in Central Minnesota about 40 percent of shallow wells have nitrate in excess of the health standard; on average, shallow groundwater in agricultural areas has much higher nitrate concentrations than in urban areas. During the monitoring period, one-third of the wells across the state showed increased chloride concentrations. Published in September 2013. Read the executive summary.
