Per- and polyfluoroalkyl substances (PFAS) are a very large class of human-made chemicals. Since the 1940s, PFAS have been produced and used in various industries worldwide. PFAS are found in everyday items such as food packaging and non-stick, stain-resistant, and water-resistant products, including clothing and other items. PFAS are also widely used in industrial applications and firefighting. PFAS can enter the environment through production or waste streams and can persist in the environment and the human body. There is toxicological evidence that some PFAS can cause harmful health effects in animals and humans.

Aquagroup has researched which methods work best for removing PFAS from drinking water. Some PFAS are soluble in water and can uncontrollably enter our drinking water. Due to the chemical properties of PFAS, we have discovered that certain technologies are better able to remove some PFAS from drinking water than others, particularly perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), the most studied of these chemicals.

Effective technologies include activated carbon adsorption, selective resins, and high-pressure membranes such as reverse osmosis. These technologies can be used in drinking water treatment plants, in water systems in hospitals or individual buildings, or even in homes at the point where water enters the house or at a point where it is used, such as a sink or a lavatory.
