Mike Parsen, a hydrogeologist at the Wisconsin Geological and Natural History Survey (WGNHS), completed a 5-year study in 2017 that evaluated the impacts of industrial sand mines and irrigated agriculture on the Chippewa County’s water resources.
In 2012, the WGNHS partnered with hydrologists Mike Fienen and Paul Juckem of the U.S. Geological Survey Wisconsin Water Science Center (USGS-WWSC) to conduct the groundwater study. This study was commissioned by the Chippewa County Department of Land Conservation and Forest Management to evaluate groundwater quantity and ensure the sustainability of groundwater resources. These issues are of particular importance to Chippewa County where a proliferation of high-capacity wells are placing increasing demands on available groundwater. “The results of this study provided sound scientific information to support informed decision-making at the county,” said Parsen.
The cornerstone of this project is a groundwater flow model developed by the WGNHS and USGS collaborators. The model can be used to simulate the flow of groundwater and its connection to surface water. The model provides water resource managers with a tool to evaluate the impacts of high-capacity wells to nearby streams and wells, to develop wellhead protection plans, to evaluate potential effects of changing land-use on groundwater, and to quantify the relationships between groundwater and surface water. Parsen said, “The results are of direct value to the public, mine operators, farmers, and local units of government.”
