Series: Waukesha And Lake Michigan Water

The Milwaukee suburb of Waukesha received approval in 2016 to draw drinking water from Lake Michigan after a years-long bid to replace its radium-tainted groundwater supply. Waukesha became the first community not located within the Great Lakes Basin to gain access to this water source. The decision marked an historic test of the binational Great Lakes Compact between the U.S. and Canada governing use of the five lakes. As Waukesha prepares to start accessing the water by the early 2020s, controversies continue over how it will affect state and regional waterways and the precedent it sets in Great Lakes water policy.
