The EPA is checking if some chemicals called PFOA, PFOS, and PFBS are safe in water and food to keep people healthy. They want people to share their thoughts by February 24, 2025, before they make a final decision.
Summary AI
The Environmental Protection Agency (EPA) has released draft national recommended water quality criteria for public comment, focusing on three per- and polyfluoroalkyl substances (PFAS): perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorobutane sulfonic acid (PFBS). These criteria are designed to protect human health and are based on the latest scientific data, providing states and tribes with information for setting their own water quality standards. Comments on this draft can be submitted until February 24, 2025, and the EPA will use this feedback to finalize the criteria. Once finalized, these recommendations will offer guidance on minimizing health risks from PFAS exposure in drinking water and aquatic food sources.
Abstract
The Environmental Protection Agency (EPA) is announcing the availability of draft Clean Water Act (CWA) national recommended ambient water quality criteria (AWQC) for the protection of human health for three per- and polyfluoroalkyl substances (PFAS)-- perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorobutane sulfonic acid (PFBS)--for a 60-day public comment period. The EPA has developed these draft PFAS national recommended human health criteria (HHC) to reflect the latest scientific information, consistent with current EPA guidance, methods, and longstanding practice. When PFAS national recommended HHC are finalized, they will provide information that States and Tribes may consider when adopting water quality standards.

The document from the Environmental Protection Agency (EPA) announces the availability of draft national recommended water quality criteria focused on three chemicals known as PFAS: perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), and perfluorobutane sulfonic acid (PFBS). These criteria aim to protect human health by guiding states and tribes in setting their water quality standards.
General Summary
These substances—PFOA, PFOS, and PFBS—belong to a larger group of chemicals widely used for their resistance to heat, water, and oil. However, research has indicated potential health risks from exposure to these chemicals, even at low levels. These concerns have led the EPA to draft criteria designed to limit human exposure through water consumption and aquatic food sources. The public is invited to comment on these drafts until February 24, 2025, after which the EPA will finalize the recommendations.
Significant Issues and Concerns
One major issue is the technical complexity of the document. It includes chemical names and EPA methodologies that may prove challenging for a general audience to understand without a background in environmental science or law. Terminologies like "bioaccumulation factors" and "relative source contribution" appear without accessible explanations, potentially alienating readers unfamiliar with such terms.
The lack of explicit reference to specific data sources might also be concerning. For example, the draft mentions using "90th percentile per capita rates" and "mean body weight for adults" based on national survey data, but it does not specify where these data were sourced from, which could raise questions about the transparency of the process.
Impact on the Public
Broadly, this document signifies a proactive step toward minimizing public health risks associated with PFAS exposure. By understanding potential exposure through drinking water and aquatic food, these criteria can guide future regulatory actions that protect public health. As public health becomes increasingly prioritized in regulatory discussions, this draft represents progress toward evidence-based environmental standards.
Positive and Negative Impact on Stakeholders
For states and tribes, these criteria provide valuable scientific data as a foundation for developing or adjusting their water quality standards. This can enhance local capacity to safeguard public health effectively, which is particularly beneficial for areas with significant PFAS contamination issues.
On the other hand, industries engaged in manufacturing or using these chemicals might face stricter regulations, potentially leading to increased costs associated with compliance. This could negatively affect economic aspects if industries are required to invest in new technologies or processes to reduce PFAS emissions.
Overall, the draft criteria reflect an ongoing effort by the EPA to link scientific research with policy-making in a bid to protect human health. While the technical nature of the document may challenge some readers, its implications could guide future regulations that mitigate risks from chemical exposure in the environment.
Issues
• The document does not detail specific funding amounts or resource allocation, which might prevent assessment of wasteful spending.
• There is no information in the document indicating favoritism toward particular organizations or individuals.
• The language is highly technical, referencing specific chemical names and EPA methodologies that may not be clear to a general audience without expertise in environmental science or regulatory processes.
• Some terminology like 'bioaccumulation factors' and 'relative source contribution' is used without lay explanations, which could make the content inaccessible to non-experts.
• The document mentions '90th percentile per capita rates' and 'mean body weight for adults' based on national survey data without specifying the sources or results of these surveys.
• The term 'final national recommended HHC' is used multiple times but does not define what the finalized criteria entail in practical terms for non-technical readers.
