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.

The Animated Nitrogen Cycle

This animation of the biogeochemical nitrogen cycle illustrates the main steps of the cycle in air, water, and soils. The video explains and connects the many forms of nitrogen, such as ammonia, ammonium, hydroxylamine, nitrite, nitrate, nitrous oxide, and nitrogen dioxide, and explains the role of nitrate in nitric oxide signaling in the human body.
