This project will investigate how per- and polyfluoroalkyl substances (PFAS), known as “forever chemicals,” are transported through the air and into surface water in the Great Lakes region. PFAS measured in rainwater samples will be used to trace PFAS from rain to lake sediments and river waters. Atmospheric modeling will also trace the trajectory of PFAS through the atmosphere to identify where it originated.
This study will demonstrate a framework to track PFAS from sources through rain and into rivers and lakes. This framework will lead to better-informed decision-making processes for inter-state and inter-region water management.
