WAUKESHA, Wis. — Lake Michigan is just 15 miles from this city of 70,000 in the Milwaukee suburbs. But these days it seems like a gigantic, shimmering mirage, tantalizingly out of reach.
The aquifer that has provided most of Waukesha's drinking water for the last century has dropped so far that what's left has unhealthy levels of radium and salt. The city would like to draw from the Great Lakes, just as more than 40 million people in eight states — from Minnesota to New York — and two Canadian provinces do every day.
If only it were that simple.
Though the lakes are so vast they hold one-fifth of all the fresh water on the earth's surface, the states with rights to it have always guarded them jealously and aren't in a generous mood after more than a decade of abnormally low levels. Their permission is required to tap in from outside the watershed, and approval for Waukesha — which lies barely on the wrong side of the line — is far from certain.
The ban on piping Great Lakes water beyond the boundary was established five years ago to keep the drought-stricken Sun Belt from siphoning off the region's greatest resource. But it's also creating winners and losers in the economically strained states around the lakes.
Waukesha's request is a test case of whether the ban will cause neighbor-versus-neighbor clashes as cities in the Midwest fight for any advantage in luring jobs and people. Many hope to build economies around water-based technology, even as heightened demand and climate change create shortages.
A recent report identified at least seven other cities in Wisconsin, Indiana and Ohio that are in the same predicament as Waukesha and may come calling for lake water.
"The Great Lakes aren't a cooler full of water to parcel out," said Joel Brammeier, president of the Alliance for the Great Lakes, which produced it. "They're a globally unique ecosystem."
