The Latest on the ‘Forever Chemicals’: An Overview of Per and Polyfluoroalkyl (PFAS) Substances


Per and polyfluoroalkyl substances (often called PFAS) are man-made (synthetic) chemicals that have properties that allow them to repel substances such as water and oil. Hence, they are found in many different consumer, commercial, and industrial products. PFAS chemicals are used in various applications and products from fire fighting foam to food packaging, non-stick cookware, stain-resistant furniture and carpets, water-repellent clothes, cleaning products and more.

PFAS enter the environment from a variety of sources including manufacturing facilities; locations where they are used such as fires / fire practice; disposed of and/or spilled. Chemical plants, industrial facilities, landfills, and wastewater treatment plants may all contribute PFAS to the environment. Once in the environment, PFAS chemicals are long lasting, and tend to break down very slowly over time allowing them to impact the food chain or perhaps our water supplies. As we learn more about these substances, and their fate in the environment concerns are developing around the potential for harmful effects on fish, animals, and humans.

This webinar will highlight the PFAS surveillance that Ministry of Environment, Conservation, and Parks has carried out across Ontario and discuss the recent drinking water guideline consultations from Health Canada and the United States Environmental Protection Agency.
