Recent research has found that water contaminated with PFAS, also known as “forever chemicals,” could be contributing to an increase in cancer rates across the United States. These chemicals, commonly used in products for their water and stain-resistant qualities, persist in both the environment and the human body, leading to potential health risks.
What Are PFAS?
PFAS, or Per- and polyfluoroalkyl substances, encompass thousands of chemicals widely used in manufacturing and consumer products. Found in items such as furniture, food packaging, non-stick cookware, and even cosmetics, PFAS are praised for their durability but are also known to linger in the environment and the human body for years. The chemicals have been linked to a variety of health problems, including reproductive issues, developmental delays, obesity, and notably, cancer.
Cancer Risk Linked to PFAS
A recent study published in the Journal of Exposure Science and Environmental Epidemiology shows a significant association between PFAS contamination in drinking water and an increased incidence of various cancers. Researchers analyzed data from U.S. counties where PFAS levels exceeded recommended limits, comparing it with cancer rates from the National Cancer Institute’s SEER Program.
The study revealed that areas with higher PFAS levels had a 2% to 33% increase in cancer incidence, with digestive, respiratory, and oral cancers showing the most significant rise. Interestingly, the types of cancer varied between sexes, with males having higher rates of urinary, brain, and leukemia cancers, while females showed increased rates of thyroid and oral cancers.
While these findings point to a potential link, they do not prove causation. Experts caution that the study is exploratory in nature, relying on ecological data rather than individual health assessments, meaning it cannot definitively establish a cause-and-effect relationship between PFAS exposure and cancer.
PFAS Exposure: A Widespread Concern
Research estimates that PFAS contaminate about 45% of U.S. drinking water supplies. Despite this, the Environmental Protection Agency (EPA) has yet to regulate these chemicals, though plans are in place to introduce new limits in 2029. As PFAS are pervasive in many consumer products, completely avoiding exposure can be difficult.
How to Limit Your PFAS Exposure
Although it may be challenging to fully eliminate PFAS from your life, there are steps you can take to minimize your exposure:
Check Local Water Reports: Research whether PFAS are monitored in your area’s water supply.
Install a Water Filter: Consider using a filter designed to reduce PFAS and other contaminants.
Reduce Exposure Through Food Packaging: Avoid fast food packaging and non-stick cookware, both of which may contain PFAS.
The Need for Policy Change
Given the widespread presence of PFAS and the potential risks they pose, experts argue that systemic change is necessary to address this issue on a larger scale. While individual actions can help reduce exposure, lasting change will require policies and regulations to limit PFAS contamination at the national level.
As more research is needed to understand the full extent of the health risks posed by these chemicals, it remains crucial to stay informed and take steps to protect yourself from potential harm.
