A recent study conducted by the U.S. Geological Survey (USGS) has found that the drinking water from nearly half of U.S. faucets (45%) contain at least one type of potentially harmful chemical known as per- and polyfluoroalkyl substances, or PFAS. You can read the complete study here.

The study tested for the presence of 32 types of PFAS in both public water supplies and private wells, with water samples being taken from more than 700 locations across the United States in both urban and rural areas. At least 12,000 types of PFAS are known to exist.

PFAS are called “forever chemicals” due to the fact that they a very long time to break down in the environment. PFAS have been around since the 1950s, and can be found on fast-food containers, non-stick cookware coatings, firefighting foam, paints many other products most of us use every day.

PFAS have been associated with number of health concerns in humans, including certain types of cancers and developmental, metabolic, and immune disorders.

To defend against PFAS in your drinking water, make sure you have a final barrier system in place such as a Berkey® gravity-fed water filtration system with powerful filters that have been independently tested to remove perfluorinated chemicals to below detectable levels.
