Beneath the surface
Minnesota's pending groundwater challenge

Even in the land of 10,000 lakes, water is no longer unlimited. Lakes shrink, groundwater drops, wells go dry or get contaminated. Some cities have to look harder for good municipal water or pay more to treat it. Twenty years ago these were isolated problems. But three-quarters of Minnesota’s residents get their water from aquifer-tapping wells, and today parts of the state seem to be on a path that is not sustainable.

In the Twin Cities, a tussle is growing over whether growing suburbs should shift from tapping wells to pulling water from the Mississippi River. Elsewhere, Park Rapids, Marshall and other cities have had to spend millions of dollars to respond to dropping water levels or contamination. The state has mapped "areas of concern," and an ambitious plan to test 70,000 wells is renewing questions about how much farmers should be required to do to limit nitrate contamination in groundwater.

In coming months, this Ground Level project, "Beneath the Surface," will shine a light on the pressures on Minnesota’s groundwater and how residents, businesses and officials are being asked to adapt.

Water Q & A

How will climate change affect groundwater?

Can we use grass that needs less water?

Why not just fill up White Bear Lake from one of the rivers?

Do you know how much water your neighbor uses?

Can we fill up our underground water supply with stormwater?

Does Minnesota water law make it easier or harder to deal with conflicts?
