This poster paper presents a long-term project by Michigan State University (MSU) and the Michigan Department of Environmental Quality (MDEQ) to improve Michigan's ability to manage and protect its groundwater resources. The joint effort capitalizes on Michigan's statewide integration of geographic, hydrologic, and geologic data and MSU's methodological and technological innovations in groundwater modeling. This partnership has enabled real-time visual analysis of Michigan's groundwater systems and drinking water aquifers virtually anywhere in the state. The project has significant potential for reducing the cost of conducting groundwater management investigations and impacting program management practices on a statewide scale, especially with respect to source water protection.
