Anna Fehling

I conduct applied groundwater studies to improve our understanding of aquifer characteristics in Wisconsin. I communicate the results of our work to the public to support the citizens of Wisconsin and help inform management decisions. My research interests include groundwater-surface water interactions, physical hydrogeology, hydrostratigraphy, and anthropogenic and climatic effects on the groundwater system.
