This research project consisted of two separate parts. For the first part, existing data sets were compiled to evaluate the effectiveness of a constructed wetland treating mine drainage in northern Minnesota. The second part involved determining metal accumulation in peat samples from a natural wetland in northern Minnesota that receives mine drainage from a nearby seep originating from a mineralized zone related to the Duluth Complex. Metal concentrations in and metal availability from the peat samples were determined by total digestion and sequential extraction techniques. Data from the first part of the project was added to an existing database maintined by the faculty advisor and will be used for an upcoming publication. Results from the second part of the project are summarized in the attached poster, which was presented by Elaine at the WSU research celebration in April 2013.
