What's Happening?
Utilities are drawing lessons from the experience with PFAS (per- and polyfluoroalkyl substances) to better prepare for future emerging contaminants. The process of regulating PFAS took decades, but once federally regulated, utilities faced rapid compliance
deadlines. Key lessons include the importance of detailed recordkeeping and early treatment investments to streamline future compliance and cost recovery efforts. Utilities are advised to track costs and decisions related to specific contaminants, even before regulations are in place, to facilitate future legal and financial processes.
Why It's Important?
The experience with PFAS highlights the challenges utilities face in adapting to new regulations and the importance of proactive measures. By learning from PFAS, utilities can better manage future contaminants, ensuring the delivery of safe drinking water. This proactive approach can also help utilities recover costs from manufacturers if contaminants are later found to cause harm. The focus on detailed documentation and early action can lead to more efficient regulatory compliance and protect public health.
What's Next?
Utilities are advised to monitor potential future contaminants such as 1,4-Dioxane, microplastics, pharmaceuticals, and next-generation disinfection byproducts. As these substances move through the regulatory pipeline, utilities will need to prepare for potential regulations. This includes investing in treatment technologies and maintaining detailed records of actions taken to address these contaminants. The ongoing monitoring and preparation will help utilities adapt to regulatory changes and protect water quality.
