David J Hart

David J. Hart is a hydrogeologist/geophysicist with the Wisconsin Geological and Natural History Survey (WGNHS) and a Professor at the University of Wisconsin-Madison’s Division of Extension, with affiliate appointments in the Department of Geoscience and Geologic Engineering. His research focuses on applied hydrogeology and geophysics, including groundwater-surface water interactions, geothermal systems, and aquifer characterization. He collaborates with institutions such as the U.S. Geological Survey, Wisconsin Department of Natural Resources, and academic departments across civil engineering and geology.

Dr. Hart’s work emphasizes practical applications, such as using geophysics to determine bedrock depth, fiber-optic temperature sensing for geothermal systems, and groundwater education through teacher workshops. His recent projects include climate change impacts on stream temperatures and groundwater sustainability in Wisconsin. He has authored numerous peer-reviewed articles on topics ranging from hydraulic conductivity modeling to thermal response testing in heterogeneous geology.

His professional roles include serving on the Wisconsin Groundwater Coordinating Council’s Education Subcommittee and as an Associate Editor for Groundwater. He actively engages in interdisciplinary research teams, integrating geology, engineering, and environmental science to address water resource challenges.
