Per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals,” have become a significant concern in recent years due to their persistent nature and potential health risks. These synthetic chemicals are prevalent in various consumer products and have been detected in drinking water supplies across the United States. Understanding the implications of PFAS in drinking water is crucial for safeguarding your health and that of your loved ones.
What Are PFAS?
PFAS encompass a large group of man-made chemicals used since the 1940s in products designed to resist heat, water, and oil. Common applications include non-stick cookware, water-repellent clothing, stain-resistant fabrics, and firefighting foams. Their strong carbon-fluorine bonds make them highly resistant to degradation, leading to their accumulation in the environment and human body.
How Do PFAS Enter Drinking Water?
PFAS can infiltrate drinking water sources through several pathways:
- Industrial Discharges: Manufacturing facilities producing or utilizing PFAS may release these chemicals into nearby water bodies.
- Firefighting Activities: The use of PFAS-containing firefighting foams, particularly at military bases and airports, can lead to groundwater contamination.
- Waste Disposal: Improper disposal of PFAS-containing products in landfills can result in leaching into groundwater.
Once introduced into the environment, PFAS can persist for extended periods, making their way into public water systems and private wells.
Prevalence of PFAS in Drinking Water
Recent studies have highlighted the widespread presence of PFAS in drinking water:
- A study by the U.S. Geological Survey estimated that PFAS may be contaminating drinking water for up to 27% of Americans, potentially affecting approximately 95 million people. Read more in The Guardian.
- Another study found that nearly half of the U.S. population has drinking water contaminated by toxic PFAS. See the coverage in Scientific American.
These findings underscore the importance of monitoring and addressing PFAS contamination in water supplies.
Health Implications of PFAS Exposure
Exposure to PFAS through drinking water has been associated with various adverse health effects:
- Cancer: Studies have linked PFAS exposure to an increased risk of kidney and testicular cancers.
- Immune System Effects: PFAS may suppress immune function, potentially reducing vaccine efficacy and increasing susceptibility to infections.
- Hormonal Disruption: These chemicals can interfere with thyroid hormones, leading to potential thyroid disorders.
- Reproductive and Developmental Issues: PFAS exposure has been associated with complications such as low birth weight, preterm birth, and developmental delays in children.
It’s important to note that research is ongoing, and the full extent of health effects is still being studied. Read more from the EPA.
Regulatory Measures and Guidelines
The Environmental Protection Agency (EPA) has been working to address PFAS contamination:
- In recent years, the EPA established legal limits on PFAS allowed in drinking water and designated certain PFAS as hazardous substances under federal law. See some Interactive PFAS map from the Environmental Working Group known as EWG.
- The EPA has issued health advisories and guidelines to help communities assess and manage PFAS contamination.
However, regulations can vary by state, and ongoing efforts aim to establish more comprehensive standards.
Testing for PFAS in Your Drinking Water
Given the potential health risks, testing your home’s drinking water for PFAS is a prudent step. While some public water systems conduct regular testing, private well owners are responsible for ensuring their water’s safety.

Mitigation Strategies for PFAS Contamination
If testing reveals PFAS in your drinking water, consider the following steps:
- Install Water Filtration Systems: Activated carbon filters and reverse osmosis systems are highly effective at reducing PFAS.
- Use Alternative Water Sources: For drinking and cooking, consider using bottled water that has been verified PFAS-free.
- Stay Informed: Keep up with your local water quality reports and any PFAS-related advisories.
Taking proactive measures like testing your water and installing a certified filtration system can significantly reduce your exposure to these harmful chemicals.
Clean, safe drinking water shouldn’t be a mystery. With the growing body of research linking PFAS in drinking water to serious health concerns, it’s more important than ever to take action.
