Question - What technologies have been found to remove perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) from drinking water?
Answer- According to the U.S. EPA, “Certain technologies have been found to remove PFAS from drinking water, especially perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), which are the most studied of these chemicals. Those technologies include activated carbon adsorption, ion exchange resins, and high-pressure membranes. These technologies can be used in drinking water treatment facilities, in water systems in hospitals or individual buildings, or even in homes at the point-of-entry, where water enters the home, or the point-of-use, such as in a kitchen sink or a shower.” (https://www.epa.gov/sciencematters/reducing-pfas-drinking-water-treatment-technologies; accessed March 2019)
