Abstract: Mining has often been a contested issue due to its potential to negatively impact the environment. Proposed gravel mining in Rosemount, Minnesota by Dakota Aggregates is no different. Our current research and past research done by Jeff Markle and Carrie Jennings found that it is unlikely that the proposed project at the Rosemount, MN mining site will have any negative impacts on the surrounding environment, most specifically, the trout population of the nearby Vermillion River. This research, however, is still important because it could provide future guidelines for mining companies to follow in order to preserve Minnesota’s beautiful natural resources. The results of this study suggest that a 200 meters setback is reasonable and safe for the environment. This result was determined by simulating the groundwater flow near the mining site through numerical modeling with finite difference methods implemented in Mathematica. We found that temperature fluctuation were more severe in the first 100 meters and stabilized after 200 meters.

This project topic was developed in partnership with the St. Thomas Sustainable Communities Partnership.
