PFAS at landfills

This research is funded by the Hinkley Center for Solid and Hazardous Waste Management (HCSWHM) with support through the U.S. Environmental Protection Agency (U.S. EPA). Below are documents associated with each of these projects. These projects are collaborative between the University of Miami and the University of Florida
