‘Forever Chemicals’: Teflon, Scotchgard and the PFAS Contamination Crisis

In 1946, DuPont introduced Teflon to the world, changing millions of people’s lives – and polluting their bodies. Today, the family of compounds including Teflon, commonly called PFAS, is found not only in pots and pans but also in the blood of people around the world, including 99 percent of Americans. PFAS chemicals pollute water, do not break down, and remain in the environment and people for decades. Some scientists call them “forever chemicals."

Since 2001, when news erupted about the contamination of drinking water near a Teflon plant in West Virginia, EWG has been in the forefront of research and advocacy on PFAS chemicals. Links to much of our work follow. For a compelling overview of the contamination in West Virginia and its aftermath, see the acclaimed documentary film The Devil We Know, available on multiple streaming platforms.

A robust body of research reveals a chemical crisis of epic proportions. Nearly all Americans are affected by exposure to PFAS chemicals in drinking water, food and consumer products.

What are PFAS chemicals?

Per- or polyfluoroalkyl substances, or PFAS chemicals, are a family of thousands of chemicals used to make water-, grease- and stain-repellent coatings for a vast array of consumer goods and industrial applications. These chemicals are notoriously persistent in the environment and the human body, and some have been linked to serious health hazards.

What are the health effects of PFAS?

The two most notorious PFAS chemicals – PFOA, formerly used by DuPont to make Teflon, and PFOS, an ingredient in 3M’s Scotchgard – were phased out under pressure from the Environmental Protection Agency after scientific evidence of serious health problems came to light. The manufacture, use and importation of both PFOA and PFOS are now effectively banned in the U.S., but evidence suggests the next-generation PFAS chemicals that have replaced them may be just as toxic. PFAS chemicals pollute water, do not break down and remain in the environment and in people for decades.

Studies have linked PFAS chemicals to:

  • Testicular, kidney, liver and pancreatic cancer.
  • Weakened childhood immunity.
  • Low birth weight.
  • Endocrine disruption.
  • Increased cholesterol.
  • Weight gain in children and dieting adults.

In the wake of the Trump administration’s rollback of more than 100 federal environmental regulations, California has again showed leadership, with new laws to protect public health. In the past two years, EWG’s team in Sacramento shepherded numerous legislative proposals to Gov. Gavin Newsom’s desk, with nearly every bill signed into law.

The Trump administration’s assault on science has been a disaster for children, according to a report in February from the Union of Concerned Scientists. Now the election of Joe Biden and Kamala Harris offers the possibility of reversing the damage done to children’s health under the Trump administration, with its many rollbacks of public health protections and disregard for the heightened risk toxic chemicals pose to kids.

Toxic PFAS chemicals, notorious for contaminating drinking water supplies across the U.S., are harmful to nearly every human organ, and the immune system is particularly vulnerable. PFAS mixtures, which are used in a variety of consumer products, can be found in the body of nearly every American and in the developing fetus.

The Big Bang of the nationwide “forever chemicals” crisis was the revelation in 2001 that PFOA, a toxic compound used to make Teflon, had contaminated the drinking water for 70,000 people near a DuPont factory in West Virginia. Pressure from the Environmental Protection Agency forced DuPont and other companies to phase out PFOA, and they agreed not to use it after 2015.

A peer-reviewed study by scientists at the Environmental Working Group estimates that more than 200 million Americans could have the toxic fluorinated chemicals known as PFAS in their drinking water at a concentration of 1 part per trillion, or ppt, or higher. Independent scientific studies have recommended a safe level for PFAS in drinking water of 1 ppt, a standard that is endorsed by EWG.
