![]() By regulating PFOA and PFOS at the minimum amounts that tests can detect, the EPA is proposing the tightest possible standards that are technically feasible, experts said. ![]() Until now, only a handful of states have issued PFAS regulations, and none has set limits as strict as what the EPA is proposing. Public concern has increased in recent years as testing reveals PFAS chemicals in a growing list of communities that are often near manufacturing plants or Air Force bases. Over the last decade, the EPA has repeatedly strengthened its protective, voluntary health thresholds for the chemicals but has not imposed mandatory limits on water providers. Despite available federal money, "significant rate increases will be required for most of the systems" that must remove PFAS, the group said Tuesday.Įnvironmental and public health advocates have called for federal regulation of PFAS chemicals for years. The Association of State Drinking Water Administrators called the proposal "a step in the right direction" but said compliance will be challenging. The public will have a chance to comment, and the agency can make changes before issuing a final rule, expected by the end of the year. Water providers will have to monitor for PFAS. In addition, the EPA wants to regulate the combined amount of four other types of PFAS. The proposal would set strict limits of 4 parts per trillion, the lowest level that can be reliably measured, for two common types of PFAS compounds called PFOA and PFOS. Their use is now mostly phased out in the U.S., but some still remain. The chemicals had been used since the 1940s in consumer products and industry, including in nonstick pans, food packaging and firefighting foam. ![]() The agency estimates the rule could reduce PFAS exposure for nearly 100 million Americans, decreasing rates of cancer, heart attacks and birth complications.

They don't degrade in the environment and are linked to a broad range of health issues, including low birthweight and kidney cancer. PFAS, or per- and polyfluorinated substances, are a group of compounds that are widespread, dangerous and expensive to remove from water. The plan would limit toxic PFAS chemicals to the lowest level that tests can detect. Environmental Protection Agency on Tuesday proposed the first federal limits on harmful "forever chemicals" in drinking water, a long-awaited protection the agency said will save thousands of lives and prevent serious illnesses, including cancer.
