EAST BRUNSWICK, NJ - April 7th, 2026 - New Jersey residents are drinking significantly cleaner water than they were less than a decade ago, thanks to concerted efforts to reduce levels of per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals." A recent study released today by the Environmental Working Group (EWG) confirms a dramatic decline in PFAS contamination in the state's tap water, offering a glimmer of hope in what has been a long-standing public health concern.

The EWG's analysis, building upon data from mandatory testing conducted by New Jersey water utilities, reveals a substantial reduction in PFAS levels from an average of 133 parts per trillion (ppt) in 2018 to just 15 ppt in 2024. This represents an almost 90% decrease, demonstrating the positive impact of proactive regulatory measures and investment in water treatment technologies.

"This is a remarkable achievement, and a testament to New Jersey's commitment to protecting public health," stated David Andrews, a senior scientist at the EWG. "However, 15 ppt is not zero, and continued vigilance and further reduction are essential. Our goal should be the complete elimination of these harmful chemicals from our drinking water."

New Jersey first established itself as a national leader in addressing PFAS contamination in 2018 by enacting some of the nation's most stringent standards for these chemicals in drinking water. These regulations mandated comprehensive testing by water utilities and required implementation of treatment strategies to lower PFAS levels. Complementing these regulations, the state launched a robust program to identify and remediate sources of PFAS contamination throughout the state - a complex undertaking given the pervasive nature of these compounds.

The Persistence of PFAS: A Continuing Concern

PFAS are a group of man-made chemicals notorious for their extraordinary persistence in the environment. Unlike many other pollutants, they do not break down naturally, leading to their widespread presence in water, soil, and even the air we breathe. Their resistance to degradation is the very property that made them so useful in countless industrial and consumer applications, including non-stick cookware, firefighting foam, food packaging, and various manufacturing processes. Unfortunately, that same property now presents a significant environmental and health challenge.

The health risks associated with PFAS exposure are increasingly well-documented. Studies have linked these chemicals to a range of adverse health effects, including certain types of cancer (kidney and testicular cancer being primary concerns), thyroid disease, immune system suppression, developmental issues in children, and disruptions to hormone function. The potential for long-term health impacts has prompted growing public demand for stricter regulations and remediation efforts.

Beyond Regulation: Identifying and Eliminating Sources

While New Jersey's regulatory framework has undoubtedly played a crucial role in reducing PFAS levels in tap water, experts emphasize that addressing the problem requires a multi-faceted approach. Identifying and eliminating the sources of PFAS contamination is paramount. This includes phasing out the use of PFAS in manufacturing processes, developing safer alternatives to PFAS-containing products, and implementing effective strategies for managing and disposing of PFAS-contaminated waste.

"We've made great strides in treating contaminated water, but we can't simply treat our way out of this problem," Andrews explained. "We need to stop PFAS from entering the environment in the first place. This requires a combination of stricter regulations on industrial discharges, responsible product stewardship, and investment in research and development of safer alternatives."

The state's ongoing efforts also involve expanding testing to include private wells, which are not subject to the same regulatory oversight as public water systems. This is particularly important in rural areas where residents rely on well water as their primary source of drinking water. Preliminary data from expanded well testing is expected later this year.

The EWG study serves as both a cause for celebration and a call to action. While New Jersey's progress in reducing PFAS contamination is commendable, the journey towards eliminating these "forever chemicals" from our water supply is far from over. Continued investment in research, treatment technologies, and source control measures will be vital to protecting public health and ensuring access to safe, clean drinking water for all New Jersey residents.
