The Minnesota Department of Natural Resources is requesting proposals for the purpose of a Coordinated Sulfate Research Effort for the Mining Regions of Northeastern Minnesota. Up to $600,000.00 in research support is being made available for this effort. Work is proposed to start after April 1, 2012. Successful respondents will have the responsibility of designing and conducting measurements needed to evaluate geochemical processes in at least one of the following subject areas: (1) Sulfur cycling and related processes that may enhance methylmercury loading (2) Site-specific methylmercury production, transport, and degradation processes and (3) Mercury bioaccumulation as a function of mercury speciation. No additional specifications were given.
