Quick takeaways
The widespread presence of PFAS chemicals in consumer products, including makeup and cookware, poses health risks despite their durability and water repellent properties.
The origin of PFAS chemicals dates back to the 1930s when DuPont discovered substances with strong carbon-fluorine bonds, leading to health concerns in communities like Parkersburg, West Virginia.

PFAS Chemicals: A Persisting Threat
PFAS chemicals, known as forever chemicals, are widely used in consumer products due to their durability and water repellent properties. Despite being linked to health issues like liver disease, PFAS chemicals are present in various everyday items, including makeup, carpet, and cookware. Their regulation by the EPA in drinking water marks a significant step in addressing their widespread presence and potential harm.
Historical Origins and Health Concerns
PFAS chemicals originated in the 1930s as DuPont sought a durable refrigerant, leading to the discovery of substances with strong carbon-fluorine bonds. Studies revealed health risks as early as the 1960s, with workers exhibiting abnormal liver function and animals experiencing adverse effects. Communities, like Parkersburg, West Virginia, faced contamination, highlighting the need for regulatory action to mitigate health threats.
Regulatory Challenges and Consumer Impact
Regulating PFAS chemicals poses a challenge due to the extensive range of compounds and their presence in various products beyond drinking water. While the EPA focuses on specific PFAS regulations, concerns persist about overall exposure levels and the effectiveness of these measures. Consumers face difficulties in avoiding PFAS exposure, highlighting the complexities of addressing this enduring health risk.
The Environmental Protection Agency has begun for the first time to regulate a class of synthetic chemicals known as “forever chemicals” in America’s drinking water.
Kim Tingley, a contributing writer for The New York Times Magazine, explains how these chemicals, which have been linked to liver disease and other serious health problems, came to be in the water supply — and in many more places.
