‘Perfluoroalkylated substances (PFAS) are synthetic chemicals, the most common being perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). PFAS are used in a wide variety of industrial and consumer products such as adhesives, cosmetics, cleaning products, and in specialized chemical applications, such as fire-fighting foams. PFAS are also used in water-, stain-, and oil-repellent coatings for fabrics and paper. (Health Canada, 2019)’

The Walkerton Clean Water Centre (WCWC) has added a new fact sheet and resources on perfluoroalkyl and polyfluoroalkyl substances (PFAS) in water systems to its Drinking Water Resource Library.
PFAS are a large group of synthetic compounds that are often referred to as “forever chemicals”. They are used in a wide variety of industrial and consumer products, such as adhesives, cleaning products, cosmetics and specialized chemical applications, such as fire-fighting foams. This group of chemicals is resistant to heat, water, oils and grease, making them highly persistent in the environment and able to accumulate in living tissues, taking several years to decades for the body to eliminate. Due to their persistent nature, the chemicals can enter drinking water wells by leaching into groundwater.
The full fact sheet and related resources can be accessed free of charge through the Drinking Water Resource Library, at:
WCWC creates fact sheets to share information with water professionals. For more information, or to request topics for future fact sheets, please visit wcwc.ca or contact us at 866-515-0550 or email@example.com.
