USGS map showing the number of PFAS detections in tap water samples from select sites across the U.S. In April 2024, the EPA issued a final drinking water rule for PFOA, PFOS, GenX, PFBS, PFNA, and PFHxS. Within three years, public water systems must remove these six PFAS to near-zero levels. States may be awarded grants up to $1 billion in aid ...
The so-called “forever chemicals” − a name attributed to PFAS' centuries-long half-life − are ubiquitous: In addition to drinking water, they are found in everything from non-stick ...
MAP: Where water systems reported PFAS contamination This map shows water systems included in the EPA’s PFAS testing records, as of July 11, 2024. It’s based on boundaries developed by ...
A new EU drinking water directive issued in 2020 adopted PFAS limit values. The limit values are 0.1 μg/L for the sum of 20 PFASs including PFHxS, and 0.5 μg/L for the sum of all PFASs. This directive is binding for all EU member nations. It is a minimum directive, and member states can elect to adopt stricter regulations. [19]
Map: Where the EPA found pollutants This map shows water systems included in the EPA’s records, as of Jan. 11. It’s based on boundaries developed by SimpleLab , a water-testing company.
PFAS accumulates in the body, which is why EPA set their limits for drinking water at 4 parts per trillion for two common types — PFOA and PFOS — that are phased out of manufacturing but still are present in the environment. Health experts say low doses of the chemicals can build up in the body over time, so even small amounts are a problem.
Perfluorodecanoic Acid (PFDA) is not a medication and does not have any approved medical uses. It is widely used as an industrial chemical, and is persistent in the environment and can accumulate in the body. Numerous studies point to its negative health effects. [23] [24] It has been detected in the blood of people and animals worldwide.
The risks of PFAS, sometimes known as "forever chemicals," have long been known. But it's more complicated than it sounds.
