Millions Exposed: 'Forever Chemicals' Found in US Water
24 Feb
Summary
- Over 151 million Americans are served by water systems with detected 'forever chemicals'.
- More than 1,050 water systems exceed EPA's new PFAS limits.
- PFAS chemicals accumulate in the body, increasing cancer risk.
Recent EPA records reveal that public drinking water systems serving at least 151 million Americans have detected toxic "forever chemicals," also known as PFAS. Over 1,050 water systems have reported average PFAS levels exceeding the EPA's newly established limits, impacting more than 52 million people.
These per- and polyfluoroalkyl substances have been manufactured since World War II for their water and heat-repellent properties. However, their persistence makes them difficult to destroy, leading to accumulation in the human body and an increased risk of certain cancers.
The EPA's regulatory standard caps PFAS at a yearly average of 4 parts per trillion (ppt). Municipalities have until 2031 to meet these new limits through advanced filtration or by securing cleaner water sources.
Data released by the EPA in February 2026 indicates that over 9,000 utilities have submitted sample data. While some cities like Bradenton, Fla., Charleston, S.C., and Buffalo, N.Y., have submitted partial results, the final update by fall 2026 is expected to show more systems in violation.
Recent updates show over 100 additional water systems now exceed the 4 ppt limit for PFOA or PFOS. Columbia, S.C., and Huntington Beach, Calif., are among the largest systems reporting elevated PFOS levels. Columbia is actively pursuing legal action against PFAS manufacturers, citing ongoing pollution concerns.
Contamination is more prevalent in urban areas, often linked to airports, military bases, and factories. Despite this, some of the highest concentrations have been reported in smaller communities, such as Oxford, Miss., and Morgantown, Pa., which reported levels significantly over the EPA's limit.
Cities like Oxford are investing in new wells and treatment plants, partially funded by federal stimulus money. Morgantown's utility shut down a contaminated well and anticipates corrections within the next year. The EPA offers resources for affected residents, recommending contacting local providers and considering home filtration systems.
