Environmental fate and transport of per- and polyfluoroalkyl substances (PFAS). PFAS can be from direct and indirect releases or emissions of PFAS from producers or industrial facilities manufacturing PFAS (outlined in red). Primary sources (outlined in orange) include consumer goods, PFAS-containing firefighting foams, landfills, and wastewater treatment plants.

Urban stormwater drains are used to channel runoff from precipitation away from roads for treatment and to prevent flooding. Contaminants in water can also be transported through stormwater systems in rain and snowmelt runoff.

Due to multiple reasons including the widespread use of microplastics, their environmental persistence, the global connectedness of aquatic environments, and the long-range transport of microplastics, these particles have been documented in every environmental compartment (e.g., air, water, soils).
