‘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.

For decades, 3M was a leading producer of the toxic fluorinated chemicals known as PFAS. As early as the 1950s, 3M’s own studies showed that PFAS chemicals built up in blood, and by the 1960s, 3M’s own animal studies showed the potential for harm. Yet 3M continued to produce PFAS chemicals without notifying its employees of the risks.

As far back as 1950, studies conducted by 3M showed that the family of toxic fluorinated chemicals now known as PFAS could build up in our blood. By the 1960s, animal studies conducted by 3M and DuPont revealed that PFAS chemicals could pose health risks. But the companies kept the studies secret from their employees and the public for decades. Here is a timeline of internal memos, studies and other company documents detailing the two companies’ history of deception.

In 2001, attorney Robert Bilott filed a federal class-action suit against DuPont for polluting the drinking water of more than 70,000 people in and around Parkersburg, W.Va., with PFOA, a Teflon chemical known within the company as C8. Bilott also wrote to the Environmental Protection Agency, supplying thousands of documents detailing DuPont’s decades-long coverup of the hazards of PFOA.
