What You Need to Know About Forever Chemicals in Drinking Water

Latest Developments from the EPA on PFAS Regulations
The Environmental Protection Agency (EPA) recently announced plans to relax regulations on some harmful “forever chemicals” known as PFAS, or perfluoroalkyl and polyfluoroalkyl substances. This decision comes approximately a year after the Biden administration established the first-ever national standards aimed at controlling these controversial chemicals in drinking water.
These chemicals have been manufactured for decades and are prevalent in various consumer products, including nonstick cookware, firefighting foam, and water-resistant fabrics. Due to their chemical stability, PFAS resist breaking down in the environment, leading to widespread contamination of air, water, and soil.
Health Risks Associated with PFAS
Concerns surrounding PFAS significantly stem from their potential health risks. Research indicates that these substances accumulate in human bodies and could lead to various health issues, including:
- Kidney disease
- Low birth weight
- High cholesterol
- Certain cancers
Due to these serious health implications, the Biden administration previously set strict limits for two common types of PFAS, known as PFOA and PFOS, capping their amounts at 4 parts per trillion. This decision reflected the growing understanding of their harmful effects, which have been supported by mounting scientific literature.
The Shift in Policy Under the Current Administration
Under the Trump administration, there was a significant push for fewer environmental regulations, which the EPA has continued with this latest announcement. While the agency intends to maintain the existing limits for PFOA and PFOS, it has proposed rescinding limits on three lesser-known PFAS types, including GenX, along with substances like PFHxS and PFNA. Furthermore, the agency plans to extend compliance deadlines for utilities, allowing them additional time until 2031 to adapt to the previous rules.
This policy shift has raised concerns among environmental groups and public health advocates. Many argue that relaxing limits could exacerbate public health issues, thus jeopardizing the safety of drinking water. Erik Olson, a senior strategist at the Natural Resources Defense Council, stated, “The law is very clear that the EPA can’t repeal or weaken the drinking water standard.”
Reactions to the EPA’s Decision
The announcement has been met with a mixed response. Environmental advocates expressed disappointment, emphasizing that reducing regulations could have adverse effects on public health. On the other hand, some industry representatives, including the American Chemistry Council, have raised questions about the scientific basis for the stricter regulations.
Utility groups, including the American Water Works Association and the Association of Metropolitan Water Agencies, showed support for some aspects of the decision, particularly the withdrawal of the novel approach to limiting a mixture of PFAS chemicals. However, they acknowledged that the changes do not significantly ease the financial burden of complying with PFAS regulations.
The Broader Implications for Water Safety
As the EPA moves forward with these changes, the long-term impact on drinking water safety remains a critical concern. With nearly 12% of U.S. water utilities reporting PFAS levels above previously established limits, many municipalities will still need to monitor and address contamination from the two most common types, PFOA and PFOS.
Utilities and industry stakeholders stress the need for more time to meet the already stringent standards, which are increasingly critical as awareness about PFAS contamination grows. The actions taken by the EPA will undoubtedly shape the future landscape of environmental policy and public health.
As the implications of this decision unfold, stakeholders will be observing how these changes affect water quality across the country and whether the rollback of these regulations ultimately results in a deterioration of public health standards.
