As an environmental laboratory specializing in PFAS analysis, Advanced Environmental Laboratories, Inc. (AEL) is committed to helping clients navigate critical regulatory changes that impact water quality testing and compliance—throughout Florida and across the nation. On May 14, 2025, the U.S. Environmental Protection Agency (EPA) released an update on its National Primary Drinking Water Regulation (NPDWR) for per- and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals.” These updates mark a significant step in addressing PFAS contamination in drinking water and set enforceable standards for the first time.
Key Takeaways from the EPA’s PFAS Regulation Update
- Enforceable Limits for PFOA and PFOS:
The EPA has established Maximum Contaminant Levels (MCLs) for two of the most hazardous PFAS compounds.- PFOA: 4 parts per trillion (ppt)
- PFOS: 4 ppt
- Rescission of Limits for Other PFAS: Previously, the EPA had set limits for additional PFAS compounds, including HFPO-Da (GenX chemicals), PFNA, PFHxS, PFBS, as well as the Hazard Index. However, the agency intends to rescind these limits and will reconsider regulatory determinations.
- Compliance Timeline Extended:
Public water systems must complete initial monitoring, with compliance extended to 2031. This timeline provides utilities time to assess and implement necessary treatment solutions. The EPA will issue the proposed rule in the fall of 2025 and finalize in Spring of 2026.
Implications for Water Utilities and Stakeholders
- Monitoring and Testing:
All Community Water systems (CWS) and Non-Transient, Non-Community Water Systems (NONCWS) must conduct regular monitoring for PFOA, PFOS according to the guidelines established by NPDWR. This includes quarterly or biannual monitoring according to system size. - Treatment Implementation:
Utilities may need to evaluate and upgrade treatment technologies to meet the new MCLs by 2031. Solutions such as granular activated carbon (GAC), ion exchange resins, and reverse osmosis are commonly used for PFAS removal. - Public Communication:
Transparent communication with consumers about water quality and steps taken to address PFAS contamination remains a critical responsibility. This includes timely notifications and clear educational materials when exceedances or treatment efforts occur.
Available Support and Resources
To help communities meet these new requirements, the EPA has outlined significant financial support, particularly for small and disadvantaged communities:
- Drinking Water State Revolving Fund (DWSRF):
Funding is available through the DWSRF, including dedicated resources from the Bipartisan Infrastructure Law (BIL), which provides $9 billion specifically for PFAS and other emerging contaminants. - Additional Support:
Financial relief may also come from legal settlements with PFAS manufacturers, which are intended to offset treatment and infrastructure costs for affected communities. - Start Planning Early:
Partnering with an experienced lab early can streamline compliance planning and reduce costly delays when mandatory testing begins. Learn more about our PFAS testing services. Early compliance monitoring gives your system more time to evaluate and implement cost-effective PFAS treatment solutions before the deadlines.
