Managing Mineland Sulfate Release in St. Louis River Basin 2009 Report

Document
Description
Over a century of iron mining in northeastern Minnesota has left numerous waste rock piles, open pits, and tailings basins that appear to be the dominant sources of sulfate in the St. Louis River. This sulfate has become a recent environmental concern due to the possibility that one of the byproducts of its increased presence, methylmercury, may lead to mercury contamination in fish and other wildlife. Through this appropriation, the Minnesota Department of Natural Resources and the University of Minnesota are evaluating the sources and fate of sulfate in the St. Louis River Basin in order to better understand its impacts and determine the best means for reducing or eliminating these impacts, particularly in environments where methylmercury is a byproduct of sulfate presence.
