This course provides an extensive overview of PFAS (Per- and polyfluoroalkyl substances) and their impact on water quality, human health, and the environment. It covers the chemistry, sources, health effects, regulatory actions, and risk assessment paradigms related to PFAS contamination. Discussions delve into the persistence of PFAS, their presence in various products and environmental sources, regulatory protocols, and the intricate health risks posed by exposure to these chemicals.

Key points highlighted in the course include the unique molecular structure of PFAS, their stability and resistance to environmental degradation, the role of regulatory bodies like the EPA in managing PFAS contamination, risks associated with exposure, potential carcinogenic effects, and strategies for risk assessment and management. EPA's initiatives and regulations to address PFAS contamination, such as proposing national drinking water standards, identifying and controlling exposures, and quantifying risks, are detailed.

The course underscores the need for comprehensive risk assessment measures, setting Maximum Contaminant Level Goals (MCLGs) and Maximum Contaminant Levels (MCLs) for protecting human health, and the challenges in replacing PFAS with safer alternatives. The course emphasizes the complexities surrounding PFAS use, exposure pathways, and the ongoing efforts to mitigate the risks associated with these persistent chemicals in the environment.
