The Minnesota Pollution Control Agency’s 2012 list of Impaired Waters contains 187 new reaches of creeks, streams and rivers in the Lake Superior, Rainy River and the Upper Mississippi River watershed basins of the Arrowhead region that are impaired for mercury contamination in fish tissue or for harm to “aquatic life.” Many of these impaired waters have been impacted by sulfates that increase methylmercury contamination of fish and by pollution from taconite waste rock stockpiles and leaking tailings ponds.

See the pages from the MPCA’s 2012 “Impaired Waters” list that identify new creeks, streams and river reaches in the Lake Superior, Rainy River and Upper Mississippi basins that are impaired for mercury contamination or harm to aquatic life.

The MPCA’s listing of waters impaired for aquatic life is an important step in protecting fish and the aquatic ecosystem from sulfates and toxic metals discharged from mines.

Despite progress in protecting fish, the MPCA’s 2012 Impaired Waters list has an important omission. It fails to identify any waters of the State that are impaired for their use to support natural stands of wild rice.

The MPCA has received information from citizens, tribal authorities and from its own monitoring reports demonstrating that many wild rice waters have levels of sulfates that exceed water quality standards and impair the propagation and maintenance of wild rice. Listing wild rice impaired waters is required under the Clean Water Act and is an important step in limiting the total levels of sulfate pollution that can be released to wild rice waters.

Thanks to all who wrote MPCA to Include Wild Rice Waters in Impaired Waters List.

The deadline was February 27, 2012 for public comment by email to howard.markus@state.mn.us or by calling Howard Markus at 651-757-2551 or 800-657-3864. Supporters urged:

  1. The MPCA’s work to identify and list Minnesota’s waters that are impaired for aquatic life is a positive step to control pollutants, including sulfates and toxic metals from existing and expanding mines, that harm fish and the aquatic ecosystem;
  2. The MPCA must also identify and list Minnesota waters that are impaired for ability to sustain wild rice and are in violation of Minnesota’s wild rice sulfate standards.
