Sulfide mining, wild rice & PolyMet

This article highlights the fact that environmental activists aren’t trustworthy. For years, we’ve heard activists from the Sierra Club, Conservation Minnesota and Friends of the Boundary Waters tell us that the sulfur embedded within the copper deposits will stunt the growth of wild rice while poisoning the water.

Pro-mining people questioned the environmental activists’ claims throughout. We’re finding out why the pro-mining people were skeptical. First, before getting into that, I wrote about a University of Minnesota study on wild rice growth a couple years ago. The study reported that rice growth was stunted except when there was high concentrations of iron in the water. The study found that iron mitigated the damage sulfur caused to the rice.

I said back then that there was a pretty high probability that water flowing through the Iron Range would have high concentrations of iron in it. Back then, I quoted from an LTE that said “In 2013 the state hired the University of Minnesota to do a scientific study of the effects of sulfates on wild rice and to determine what the standard should be. Also the Minnesota chamber hired an independent laboratory to do the same. Both studies agree that sulfate is not toxic to wild rice. The studies also found that if sulfates turn to sulfides it does slow the growth of wild rice. However if there is iron present in the water, iron combines with the sulfides and doesn’t allow the sulfides to affect the wild rice.”

This picture is worth thousands of words of anti-mining spin:

The caption reads “A Picture Worth a Thousand Words: Much has been written lately about how sulfate discharges from mines may stunt wild rice growth. Here is a photo of wild rice on Birch Lake (Dunka Bay) ‘stunted’ by sulfate discharges in the Dunka River from the Dunka and Northshore mines. Why are new studies needed when actual results already exist? Photo by Pete Pastika.” Good question, Pete. Personally, I think the time for studies is over. The time for Minnesota to approve the final permits is now.
