Sometimes referred to as “Forever Chemicals”, chemicals that do not easily break down in the environment, PFAS represents a large family of synthetic Perflourakyl and Polyflourakyl compounds that have been used since the 1940s. PFAS may be listed in a variety of ways, relating to more specifics forms, including PFOS, PFOA, PFHx, PFNA, and PFDA to name a few. While the exact number of PFAS chemicals is hard to pin point, as they are still be used and created today, the number likes ranges in the 1000’s.

PFAS chemicals are used in a wide variety of popular applications including water resistant fabrics like rain jackets, non stick cookware, stain resistant coatings for carpets and upholstery, and personal care products to name a few.

However, the current understanding of these chemicals continues to grow with more research. While it is unknown what level, if any, is safe for people and animals, PFAS does accumulate in the body. Some studies have shown that high exposure to PFAS may result in unwanted health affects including: Increased cholesterol, hormone disruption, infertility, high blood pressure, liver damage, and risk of kidney or testicular cancer to name a few.

Due to the possible health implications, regulating PFAS in drinking water is becoming more common, with some looking to ban PFAS as a whole (IE New Zealand’s ban in cosmetic products starting in 2026). Regulating PFAS in water is now being monitored and/or implemented for specific PFAS known compounds include countries such as Canada (2024), UK (2021 - monitoring), and the US (2024) with many more nations looking to follow.
