PFAS (per- and poly-fluoroalkyl subatances) are a large group of manmade fluorinated chemicals which include the widely used chemicals perfluorooctanoic acid or PFOA, and perfluorooctanesulfonate or PFOS. There are over 4,000 compounds that have been identified as PFAS to-date. These pervasive chemicals are contained in everyday consumer products like non-stick cookware, flame retardant clothing, furniture and carpets, as well as other industrial products like firefighting foams.
Scientists are still learning about possible health effects from being exposed to these chemicals. Links to cancer, liver damage, and low birth rate are among the concerns listed. Interest over drinking water and wastewater contamination, in particular the land spreading of biosolids (often referred to as “sludge”), has emerged as the public tries to more fully understand the issue.
