EPA Proposes New Regulation to Limit Presence of Harmful PFAS Chemicals in Drinking Water

The Environmental Protection Agency (EPA) has proposed a new regulation to limit the presence of per- and polyfluoroalkyl substances (PFAS) in drinking water. The proposed regulation would set legally enforceable levels for six manufactured chemicals that are known to contaminate drinking water and pose significant health risks, including cancer, even at low levels.

The EPA’s proposal would require public water systems to monitor the chemicals and alert the public if the chemicals exceed the maximum contaminant levels. The proposed regulation builds on previous EPA proposals and regulations, and is the first time the federal government has suggested setting such a standard for the so-called “forever chemicals.”

The six PFAS chemicals covered by the proposed regulation are slow to break down, and are known to occur in drinking water. The EPA has identified them as a health concern due to their potential to cause cancer, even at low levels.

The proposed regulation is part of the Biden administration’s efforts to reduce harmful chemicals in drinking water. The EPA is currently seeking public comment on the proposed regulation, and will consider all comments before finalizing the rule.

The EPA’s proposed regulation is a major step forward in protecting public health and the environment from the potential risks posed by PFAS chemicals. If implemented, the regulation would provide much-needed clarity and protection for drinking water supplies across the country.
