Per- and Polyfluoroalkyl Substances (PFAS) are chemicals with known adverse health effects. PFAS have been present for decades in industrial and commercial use because of their versatility and resistance to heat, water, and oil. Due to a recent EPA program, water suppliers have been testing for PFAS in drinking water. Water suppliers have found PFAs in drinking water in multiple cities across the United States. For many, this is a politically relevant concern in upcoming midterm elections.
There has yet to be a study with definitive results involving the health implications of PFAS. However, researchers are confident that “a wide range of health effects, including cancer, low birth weight, thyroid disease, elevated cholesterol and effects on the immune systems” are linked to exposure to PFAS.
Some of the states affected include Michigan, New Hampshire, New York, Pennsylvania, and North Carolina. For a full map of exposed regions, click here.
EPA “is working on a plan to manage PFAS chemicals and expects to release it by the end of this year.” Many, however, think that agencies aren’t working quickly enough to correct the problem. You can take steps to protect your household by using carbon filters for drinking water or a full-house filtration system.
