Biography

Heather Preisendanz is a Professor in the Department of Agricultural and Biological Engineering at Penn State University. Her research focuses on the fate and transport of emerging contaminants and their impacts on aquatic species, particularly fish. Preisendanz investigates how human activities and agricultural practices influence the export of harmful compounds into surface water bodies. She has contributed significantly to understanding the coupling of hydrology and biogeochemistry, emphasizing the adverse effects of low-concentration contaminants, often detected at levels lower than 1 ng/L, on sensitive aquatic ecosystems. Her work includes research on polyfluoroalkyl substances (PFAS) and their prevalence in private wells in Pennsylvania, as well as their implications for public health and water quality.
