PFAS Regulations Tighten – and Utilities Face Tough Decisions
With the EPA’s first-ever legally enforceable limits on PFAS (“forever chemicals”) in drinking water taking effect, utilities across the U.S. are facing both pressure and legal challenges. At the heart of this issue is a difficult balance: protecting public health while managing the enormous costs of compliance.
What Are PFAS and Why Are They Dangerous?
PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals used in everything from nonstick cookware to firefighting foam. They’re extremely persistent in the environment and the human body – hence the nickname “forever chemicals.” Exposure has been linked to serious health risks, including up to a 33% higher incidence of certain cancers, according to a recent study by USC’s Keck School of Medicine.
A 2023 U.S. Geological Survey study estimates that 45% of U.S. tap water contains at least one type of PFAS, and in Central Florida, groundwater contamination is a growing concern. Testing of springs near Deltona found PFAS levels well above EPA limits in several locations, including Volusia County’s Green, Blue, and Gemini Springs.
Legal and Financial Pressures Mount
The EPA’s new rules require water utilities to begin testing for 29 PFAS chemicals by 2027 and reduce levels of six specific PFAS to meet a strict 4 parts per trillion (ppt) threshold by 2029. But utility membership groups are now challenging these rules in court, citing the staggering costs of compliance.
To meet such a low threshold, many systems will need to retrofit or rebuild water treatment facilities – an expensive endeavor, especially for smaller or underfunded municipalities. Environmental attorney James Ferraro, who represents over 20 public water systems in a separate national lawsuit against PFAS manufacturers like 3M and DuPont, says even upcoming settlement funds won’t cover the full cost of long-term monitoring and treatment.
Meanwhile, the EPA faces a fast-approaching deadline to respond to lawsuits over its rules. And amid all this, the agency has signaled internal restructuring, including staffing cuts in scientific divisions that originally identified PFAS as hazardous – raising further questions about how the EPA plans to support enforcement and research moving forward.
What’s at Stake
PFAS regulation isn’t just a political or legal issue – it’s a public health emergency. With groundwater supplying 90% of Florida’s drinking water, ensuring PFAS levels stay under control is critical for safeguarding communities.
Still, solving the problem won’t be easy. Utilities need funding, technology, and time to adapt. As Ferraro puts it, “There’s an issue; it’s a concern for public health… [but] the scope of this problem is huge.”
