Widespread PFAS Contamination Identified in U.S. Water Systems
Recent federal and state testing has revealed that nearly 200 million Americans are served by drinking water systems where toxic forever chemicals, known as PFAS, have been detected. This development comes as the Environmental Protection Agency (EPA) considers proposed rollbacks on existing drinking water protections.
New Data Highlights Larger Scope of Contamination
An analysis by the Environmental Working Group, released Thursday, estimates that PFAS have now been identified in water systems serving about 197 million people — up 23 million from previous federal testing figures. This increase reflects improvements in testing and reporting, rather than a sudden rise in contamination levels.
David Andrews, chief science officer at the Environmental Working Group, explained that while some older PFAS compounds have seen decreasing concentrations due to manufacturers phasing them out, scientific understanding of the potential health risks continues to grow. Even at extremely low concentrations, exposure to certain PFAS has been linked to cancer, immune system issues, and reproductive health risks.
Background on PFAS and Health Risks
PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals widely used in products such as nonstick cookware and stain-resistant fabrics. They are notoriously persistent in the environment, earning the term forever chemicals due to their slow breakdown. The new analysis tracks water systems where PFAS were detected, regardless of whether the concentrations exceed current federal drinking water standards.
North Carolina’s Ongoing Struggle with PFAS, Including Chemours Contamination
North Carolina continues to grapple with PFAS pollution, especially in the Cape Fear River area, where chemical manufacturer Chemours has been linked to significant contamination with GenX and other PFAS compounds. According to state data, more than 800 public water systems have been sampled since 2022, including 533 smaller systems in 2023 and 228 in 2024.
The North Carolina Department of Environmental Quality (DEQ) previously estimated that over 300 public water systems had PFAS concentrations above at least one federal standard set in 2024. Utilities such as Cape Fear Public Utility Authority, Brunswick County, Pittsboro, and Maysville have already begun addressing contamination through treatment upgrades or other interventions.
EPA Drinking Water Protections and Proposed Rollbacks
In 2024, the EPA established the first enforceable federal drinking water limits for six PFAS chemicals. However, the Trump administration last year announced plans to eliminate standards for four of those chemicals—including GenX—while keeping limits of 4 parts per trillion for PFOA and PFOS, which are among the most extensively studied PFAS substances. The EPA also proposed delaying the deadline for utilities to comply with these limits from 2029 to 2031, citing the need for smaller and rural water systems to plan and finance expensive treatment upgrades.
EPA Administrator Lee Zeldin stated in May 2025 that protections for PFOA and PFOS would be maintained, while allowing utilities more flexibility. The agency said it would reconsider the other standards to ensure compliance with the Safe Drinking Water Act. Some, including Andrews, have argued that delaying compliance could leave the public exposed to potential health risks for additional years, effectively passing the burden onto families and communities.
What Residents Can Do and Calls for Accountability
The North Carolina DEQ and the EPA had not provided comments or updated contamination figures at the time of reporting. Residents seeking the latest water testing results can visit the DEQ's PFAS sampling portal or contact their local water provider directly.
To reduce exposure risk, Andrews recommends home filtration with systems certified for PFAS reduction, such as activated carbon filters or reverse osmosis. Consistent filter maintenance is crucial for effectiveness. He emphasized that the primary responsibility for cleanup should rest on the companies that manufactured and profited from PFAS chemicals: “This is contamination caused by an industry that profited off these chemicals.”
