PFAS, also known as “forever chemicals,” have been found in nearly half of U.S. drinking water supplies, according to a recent study. The chemicals, widely used in manufacturing and consumer goods, have been linked to an increased incidence of various forms of cancer.
The study, published in the field of population health sciences, analyzed county-level data on PFAS contamination and compared it with cancer rates. The researchers found that regions with high levels of PFAS exposure had a significantly higher rate of cancer, including oral cavity/pharynx, brain, thyroid, and endocrine cancers.
PFAS are persistent chemicals that can linger in the environment and human body for thousands of years. They have been linked to harm to reproductive health, developmental delays in children, and increased risk of obesity. The chemicals disrupt the endocrine system, which regulates important bodily functions through hormone release.
While the study does not establish a causal link between PFAS and cancer, it should encourage further research in this area. Experts caution that individual efforts to limit exposure may be insufficient, and that systemic changes and policies are needed to address the widespread contamination of water supplies.
To minimize exposure to PFAS, individuals can take steps such as installing a water filter, limiting consumption of non-stick products and fast food, and looking into local or county-level water reports. However, completely eliminating PFAS from their lives may be difficult due to the prevalence of these chemicals in consumer goods.
