Forever Chemicals in Drinking Water Threatens 26M Americans

In a startling revelation that underscores the pervasiveness of a silent environmental crisis, new data from the Environmental Protection Agency (EPA) reveals that 26 million Americans are consuming water laced with harmful "forever chemicals" known as PFAS. The analysis, conducted by the Environmental Working Group (EWG), underlines the alarming prevalence of these chemicals in 431 water systems across the country, with levels exceeding minimum reporting limits.

These chemicals, which are slow to break down, pose a significant risk to human and animal health. The National Institute of Environmental Health Sciences warns that prolonged exposure to PFAS can result in an array of health issues, including altered metabolism, a weakened immune system, and an elevated risk of certain cancers. The gravity of the situation is further highlighted by the EPA’s ongoing tests for the presence of PFAS, reflecting the agency’s recognition of the potential health hazards these chemicals present.

Findings Reveal ‘Forever Chemicals’ in US Water Supply

New data from the Environmental Protection Agency (EPA), as analyzed by the Environmental Working Group (EWG), has revealed the presence of potentially harmful "forever chemicals" known as PFAS in the drinking water of approximately 26 million people across the U.S. The study found PFAS present in 431 water systems, exceeding the minimum reporting limits. This data represents about 7% of the total anticipated results over the next three years.

Health Implications of PFAS Exposure

PFAS are tested for their potential detrimental health effects on both humans and animals. According to the National Institute of Environmental Health Sciences, PFAS break down slowly and can have numerous effects on health. These include altered metabolism, a reduced capacity of the immune system to combat infections, and an increased risk of certain cancers. “For decades, millions of Americans have unknowingly consumed water tainted with PFAS,” stated Scott Faber, senior vice president for government affairs at EWG.

Call for Action and Individual Protection

Faber further claimed that evading PFAS is nearly impossible, given their widespread presence. Despite this, Faber commended the EPA’s efforts and urged President Joe Biden’s administration to finalize drinking water standards this year. Meanwhile, the EWG recommends that individuals can protect themselves against PFAS by routinely replacing at-home water filters.

Widespread Presence of PFAS

EPA Assistant Administrator for Water, Radhika Fox, underscored the urgency of the PFAS issue, linking long-term exposure to significant health risks. This report comes on the heels of a U.S. Geological Survey study which found that at least 45% of U.S. tap water is estimated to have one or more types of PFAS. This study, which tested 716 locations across the country between 2016 and 2021, was the first to test for PFAS in tap water.


The extensive presence of PFAS in U.S. water systems underscores the pressing need for comprehensive and stringent drinking water standards. While individual measures, such as using and regularly replacing at-home water filters, can provide some protection, systemic solutions are required to address this public health issue. The ongoing studies by the EPA and other organizations are a critical step towards understanding and mitigating the risks associated with PFAS exposure.
