Lake Superior Disrespect, Minnesota-To-Wisconsin?

Asbestos and sulfide pollution could be one serious price of iron ore mining in the Bad River watershed on the eastern shore of Lake Superior; on the Minnesota side, big problems, too:

A proposed copper-nickel mine in northeast Minnesota would generate water pollution for up to 500 years and require billions of dollars in long-term cleanup costs, state regulators have concluded as they near a key stage in the project’s review. 

The mine would require what critics say is essentially perpetual water treatment — a first in Minnesota’s long history of mining — to remove pollutants and heavy metals that would otherwise flow into nearby streams and rivers and eventually Lake Superior, according to a draft environmental impact statement.
