Are PFAS forever chemicals? The simple answer is yes—but understanding why these chemicals are so persistent reveals the more profound dangers they pose to the environment and human health.
PFAS chemicals, used in various industries and consumer products, have become an enduring environmental challenge. This blog will explore PFAS, why they are considered “forever chemicals,” and the associated risks to human health and the environment.
What Are PFAS?
Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals used in many products for their water- and stain-resistant properties. From non-stick cookware and food packaging to firefighting foams and waterproof clothing, PFAS have been a staple in manufacturing since the 1940s. Despite their usefulness, these chemicals come with a hidden cost: they do not readily biodegrade in the environment or the human body, leading to long-term exposure risks.
Why Are PFAS Forever Chemicals?
PFAS are called “forever chemicals” due to their unique chemical structure. PFAS contain strong carbon-fluorine bonds, one of the most durable chemical bonds. This bond makes them resistant to heat, water, and oil, but it also means they do not degrade naturally over time.
When PFAS enter the environment—whether through industrial discharge, consumer products, or firefighting activities—they accumulate in soil, water, and living organisms. Once in the human body, PFAS can linger for years, contributing to potential health issues such as hormone disruption, immune system suppression, and even certain cancers.
Where Are PFAS Found?
PFAS are virtually everywhere, from household products to industrial sites. Common sources include:
Non-stick cookware
Water-resistant clothing and textiles
Food packaging materials
Firefighting foams (especially at airports and military bases)
Stain-resistant carpets and upholstery
Contaminated drinking water
Because PFAS are so widespread and persistent, contamination can affect entire communities, posing serious environmental and health risks.
What Are the Risks of PFAS Exposure?
The resilience of PFAS in the environment leads to a range of concerns:
Bioaccumulation: PFAS build up in animals and humans over time, moving through the food chain and increasing exposure levels.
Water Contamination: PFAS can seep into groundwater, affecting drinking water supplies for entire regions.
Health Impacts: Long-term exposure to PFAS has been linked to liver damage, immune system issues, thyroid disease, and certain cancers.
Because they persist in nature and the body, PFAS represent a long-term challenge for environmental cleanup and public health protection.
How Are PFAS Managed?
Due to growing awareness of PFAS-related risks, regulatory agencies, including the Environmental Protection Agency (EPA), have introduced guidelines and restrictions on their use. However, because PFAS are so widespread and persistent, managing contamination is an ongoing challenge.
Environmental Site Assessments (ESAs) play a crucial role in identifying PFAS contamination on properties, especially for industrial sites, military facilities, and areas near known sources of PFAS discharge. Comprehensive testing and remediation strategies are essential to reduce exposure and prevent further contamination.
