For decades, a group of industrial chemicals known as PFAS quietly spread through the environment. Today, scientists are beginning to understand the full scope of their impact.
Often referred to as “forever chemicals,” PFAS do not easily break down in nature or the human body. Instead, they accumulate over time in drinking water, soil, wildlife, and even human blood. Researchers now estimate that most Americans have detectable levels of PFAS in their bodies due to widespread environmental exposure.
A growing body of research suggests these chemicals may contribute to serious long-term health risks. A recent study has raised a troubling new question: could PFAS exposure actually accelerate the aging process?
New Research Suggests PFAS May Accelerate Biological Aging
In early 2026, researchers examining health data from hundreds of Americans discovered a connection between PFAS exposure and faster biological aging, particularly among middle-aged men.
The study found that higher levels of certain PFAS compounds were associated with accelerated epigenetic aging, a biological process linked to inflammation, DNA repair, and metabolic health.
In simple terms, individuals with greater exposure to these chemicals showed biological markers indicating their bodies were aging faster than expected.
Scientists believe the chemicals may interfere with fundamental cellular processes, including mitochondrial function and inflammatory responses, both of which play key roles in aging and chronic disease.
While researchers caution that more studies are needed, the findings add to mounting evidence that PFAS exposure may affect long-term health in ways scientists are only beginning to understand.
Why PFAS Are Called “Forever Chemicals”
PFAS, short for per- and polyfluoroalkyl substances, are a large family of synthetic chemicals developed in the mid-20th century.
They became popular in manufacturing because they resist heat, grease, and water. Over the decades, PFAS were widely used in products such as:
- firefighting foam used at airports and military bases
- nonstick cookware
- stain-resistant fabrics
- food packaging
- industrial manufacturing processes
The problem is that these chemicals do not naturally degrade. Once released into the environment, they can persist for decades or even centuries.
As a result, PFAS contamination has been detected in groundwater, municipal water supplies, and ecosystems across the United States.
Growing Evidence of Health Effects
The potential health risks associated with PFAS exposure have been studied for years.
Research has linked various PFAS compounds to:
- immune system suppression
- hormone disruption
- increased cholesterol levels
- certain cancers
- pregnancy complications
- liver damage
Scientists continue to investigate how these chemicals interact with the body over time. Some studies suggest PFAS exposure may affect telomeres and epigenetic markers, which are biological indicators related to aging and disease risk.
The emerging research on accelerated aging adds another dimension to these concerns.
How PFAS Contamination Reaches Communities
Many of the most serious PFAS contamination cases stem from industrial and military activities.
Common sources include:
- firefighting foam used at airports and military installations
- chemical manufacturing facilities
- industrial waste disposal
- contaminated landfills
When PFAS enter the environment, they can migrate through soil and groundwater, eventually contaminating drinking water supplies serving entire communities.
Because these chemicals remain stable for long periods, contamination can persist even decades after the original release.
Why PFAS Litigation Is Increasing
Across the United States, communities, municipalities, and individuals have begun pursuing legal claims related to PFAS contamination.
These cases often focus on allegations that manufacturers knew or should have known about the environmental and health risks associated with these chemicals but continued widespread production and use.
PFAS litigation has already resulted in major settlements involving water providers and chemical manufacturers, and additional claims continue to emerge as scientists learn more about the long-term effects of exposure.
The Growing Need for Accountability
The emerging research on accelerated aging highlights how much scientists are still learning about PFAS.
Many people exposed to contaminated water may not immediately experience symptoms. Instead, the effects of exposure may develop slowly over years or decades.
As evidence grows linking PFAS exposure to serious health risks, affected individuals and communities are increasingly seeking answers and accountability.
Understanding the scope of contamination and the long-term risks remains an ongoing challenge, but the scientific evidence continues to evolve.
Holding Polluters Accountable for PFAS Contamination
As scientists continue uncovering the long-term health effects of PFAS exposure, legal action has become one of the primary ways communities seek accountability. Across the United States, lawsuits involving “forever chemicals” have already led to multi-billion-dollar settlements with chemical manufacturers such as 3M and DuPont over contamination in public drinking water systems.
Stag Liuzza has been actively involved in this national effort. The firm represents municipalities and public water systems pursuing claims related to PFAS contamination and has played a role in the ongoing AFFF multidistrict litigation addressing firefighting foam pollution.
PFAS contamination often begins quietly. Chemicals released decades ago can migrate through soil and groundwater, eventually affecting wells, municipal water systems, and entire communities. Many water providers only discover the problem after testing reveals contamination levels that require expensive treatment and remediation.
If your municipal water system, community well, or property may be affected by PFAS contamination, it is important to understand your legal options.
The attorneys at Stag Liuzza work with environmental scientists, investigators, and water experts to help communities identify contamination sources and pursue recovery for testing, filtration systems, and long-term cleanup costs.
If you believe your drinking water system may have been contaminated by PFAS or other toxic chemicals, you can contact Stag Liuzza to discuss the situation and learn what options may be available.
