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.

An infographic highlighting a study finding that black carp, which are an invasive fish species in North America, are now known to be established in the wild in parts of the Mississippi River basin. The infographic was created by the USGS. The USGS was one of the study’s co-authors and the research was led by Southern Illinois University.
