Basic Information about Perfluorooctanoic Acid (PFOA), Perfluorooctyl Sulfonate (PFOS) and Other Perfluorinated Chemicals (PFCs) including how people are exposed and health effects.
More than 16 million Americans drink water contaminated with toxic chemicals that can be traced to military and industrial sites, according to new research from Harvard University. 66 water...
PFAS are manufactured chemicals that have been used in industry and consumer products since the 1940s. Because of their widespread use and their persistence in the environment, many PFAS are found in the blood of people and animals all over the world. There are thousands of different PFAS, some of which have been more
Put simply: PFAS, a class of more than 4,000 different chemicals, is everywhere. It turns up in everything from household items to fast food wrappers. It’s even been found in our blood. And new...
Find state contacts and discover research, data, and tools related to EPA's understanding of PFAS. Basic information about PFOA, PFOS and other PFAS/PFCs; how people are exposed; health effects; laws and regs that apply; and what EPA and states are doing to reduce exposures.
And it’s not just public systems—a 2023 study by the U.S. Geological Survey found that approximately 20% of private wells are contaminated. These compounds are now so ubiquitous, that an estimated 98% of the U.S. population has detectable concentrations in their blood.
There is evidence that exposure to PFAS can lead to adverse human health effects. PFAS can be found in: Food packaged in PFAS-containing materials, processed with equipment that used PFAS, or grown in PFAS-contaminated soil or water.
PFAS stands for per-and polyfluoroalkyl substances, which contain a strong carbon-fluorine bond that allows them to accumulate over time in the environment and in the bodies of animals and people, posing health risks.
Toxic “forever chemicals” known as PFAS are linked to several harmful health impacts and have contaminated drinking water sources across the country. PFAS are found in everyday products like waterproof jackets, food packaging, and nonstick pans. They’re also found in a majority of the U.S. population.
PFAS stands for perfluoroalkyl or polyfluoroalkyl substances, a group of chemicals that have properties that allow them to repel water, dirt, and oil. You may know them by an older term “PFCs,”...
