PFAS in the U.S. Population

Since 1999, the National Health and Nutrition Examination Survey (NHANES) has tracked PFAS levels in the blood of the U.S. population, helping us better understand public health trends. As the use of PFOS and PFOA has declined since 2002, NHANES data reveals significant reductions in blood levels—over 85% for PFOS and 70% for PFOA by 2018. Despite this progress, exposure to other PFAS chemicals remains a concern as replacements are introduced. NHANES continues to play a key role in monitoring these changes.
