Are you wild about Wild Rice?
Come learn what the MPCA is doing to help protect the state grain.

Ed Swain
Research Scientist at the Minnesota Pollution Control Agency, and
Adjunct Professor in the Dept. of Fisheries, Wildlife, and Conservation Biology at the University of Minnesota

Synopsis:  

The presentation will include the research behind a recently-released MPCA proposal to protect wild rice from excess sulfate.  Minnesota adopted a wild rice sulfate standard in 1973 of 10 milligrams per liter, but recent questions have prompted a review of that standard and additional research into the effects of sulfate on wild rice.  The Minnesota legislature funded a 1.5 million dollar study, which the MPCA conducted from 2011 to 2014.  The research investigated the conversion of relatively harmless sulfate into potentially toxic hydrogen sulfide by bacteria in the sediment in which wild rice is rooted.  The MPCA study found that more sulfide is produced when bacteria have more organic carbon available as a food source--but that the sulfide can be detoxified by precipitation with iron in iron-rich sediments.  The MPCA proposes to replace the 10 milligram per liter standard with an equation that calculates how much sulfate would be tolerable in a given wild rice water based on the concentrations of iron and organic carbon in the sediment of each wild rice water.

Speaker Bio:  

Ed Swain has been a research scientist at the Minnesota Pollution Control Agency for 25 years, and for 15 years has been an adjunct professor in the Dept. of Fisheries, Wildlife, and Conservation Biology at the University of Minnesota.  For most of the 25 years he studied mercury contamination of Minnesota's lakes, streams, and wetlands.  But four years ago he switched to the question of why wild rice seems associated with low sulfate waters.
