Some of you may remember from Watershed that one of my brothers was developing a method of using native Minnesota bacteria from swamps and Minnesota iron to remove sulfate from water that has been impacted by closed taconite mines.

This process is of greater importance to me now since the lake I wrote about, Birch Lake, has just been put on the draft list for waters impaired for sulfate.

Here you can watch my brother explain the process he has developed, a low cost way to protect wild rice, treaty rights, and our lake.
