Understanding PFAS Regulations and Protecting Your Water Supply

As awareness grows about the health and environmental risks of perfluoroalkyl and polyfluoroalkyl substances (PFAS), otherwise known as “forever chemicals”, businesses and municipalities face new concerns about water safety. Updated federal and state PFAS regulations are taking effect, prompting many to ask how to know if their water is affected and what they can do about it.

Learn more about PFAS regulations, how to assess your risks, and options we provide to reduce PFAS chemicals from your water.

PFAS Regulations: What You Need to Know

Water regulations are evolving rapidly as new research highlights the dangers of long-term exposure to “forever chemicals.” PFAS are synthetic chemicals used in countless consumer and industrial products, ranging from firefighting foams to waterproof fabrics. Because they resist breakdown, PFAS can persist in the environment, accumulating in soil, groundwater, and drinking water systems.

In 2024, the EPA introduced the first national drinking water standards for six key PFAS compounds, including PFOA and PFOS. These rules require public water systems to monitor and reduce PFAS levels below established limits to protect human health. Many states have gone further, enforcing stricter limits and expanding testing requirements.

To understand the scope of these regulations, consider these points:

• The EPA now mandates testing for specific PFAS compounds in all public water systems.
• States may impose additional limits and require more frequent monitoring.
• Local compliance helps prevent legal, financial, and health-related consequences.
• Regulations encourage private well users to also conduct independent tests.
