What are PFAS (Per- and polyfluoroalkyl substances)

PFAS are a class of thousands of human-made substances, sometimes referred to as “forever chemicals”. Negative environmental and health effects have been observed for some well-studied PFAS.

PFAS do not break down easily and remain in the environment for a long time. They can accumulate, are mobile, can be transported over long distances, and are commonly found in the environment and humans.

Where are PFAS

PFAS can be found in air, water, oceans, and soil. They are found in wastewater, landfill run off, sewage sludge and contaminated sites. People are exposed to PFAS from many sources including food, consumer products, air, dust, and drinking water.

PFAS repel oil and water, and are resistant to heat and strong chemicals. They are used in a wide range of industries, in certain firefighting foams, and found in a range of other products, including:
