Steps Toward Better PFAS Regulation: Key Recommendations for EPA and Public Water Systems
A new report by the U.S. Government Accountability Office (GAO) urges the Environmental Protection Agency (EPA) to accelerate efforts to assist public water systems in addressing per- and polyfluoroalkyl substances (PFAS) contamination in drinking water. With new regulations set to take effect in 2029, timely action is essential to protect public health.
Current State of PFAS Regulation
In April 2024, the EPA established maximum contaminant levels (MCLs) for six PFAS chemicals, including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), with a stringent limit of 4 parts per trillion. However, the GAO report indicates that many water systems are struggling to comply with these standards.
Challenges in Treatment and Waste Management
According to the GAO’s survey, 77% of public water systems have yet to implement PFAS treatment solutions. Granular activated carbon (GAC) is the most commonly used method but produces PFAS-contaminated waste, adding to the challenge of safe disposal.
Additionally, 68% of systems have not yet devised waste management strategies, relying on landfills and incineration without clear guidelines on their long-term impacts. The absence of federal standards for PFAS waste disposal exacerbates this issue.
Lack of Communication and Financial Support
The GAO found that 86% of large water systems face challenges in effectively communicating the health risks of PFAS to the public. While the EPA has introduced a PFAS Communication Toolkit, many systems remain unaware of it. Financial constraints further hinder their ability to implement treatment systems and manage PFAS waste sustainably.
GAO’s Recommendations for the EPA
To address these issues, the GAO proposed four key recommendations:
- Establish a clear timeline for releasing communication resources to help water systems inform customers about PFAS health risks.
- Develop a compliance guide specifically tailored for small public water systems to meet the 2029 deadline.
- Improve outreach regarding funding opportunities to support water systems in combating PFAS contamination.
- Create a consolidated resource summarizing federal regulations on PFAS waste disposal.
Future Implications
Implementing these recommendations is critical for public water systems, particularly in rural or disadvantaged areas, to meet the upcoming 2029 regulatory deadline. Without adequate support and clear guidance, millions of Americans could remain at risk of PFAS exposure through their drinking water.
