As agencies continue to work on ways to manage contamination on a larger level, there are a few key things you can do to avoid exposures: voluntary industry phase-out of PFOA, whereby the major global fluorochemical companies have agreed to eliminate PFOA by 2015. Well-known consumer products have helped bring these issues into public awareness.

Both are fluorinated organic chemicals, part of a larger family of compounds referred to as perfluoroalkyl substances (PFASs). These substances are synthetic compounds that are unique for being water and lipid-resistant.

Samples of 18 Feb 2021 EPA is committed to supporting states and public water systems as they determine the appropriate steps to reduce exposure to PFOA and PFOS Though PFOS and PFOA can occur in water repellents as impurities or by- products of degradation, most water repellents on the market today are PFOS- free. Many chemicals in this group, including perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), have been a concern because they do not PFOS and PFOA testing with Element's experienced technicians can ensure that you remain compliant with a range of regulatory standards.
