Anna Fehling

I conduct applied groundwater studies to improve our understanding of aquifer characteristics and behavior in Wisconsin. I communicate the results of our work to the public to support the citizens of Wisconsin and help inform management decisions. My work typically involves collecting and analyzing field data, creating computer models of groundwater behavior, and developing decision-support tools.
