Time for Action to End PFAS Threat

Published Jan 14, 2019 Updated Jun 13, 2019

The Environmental Protection Agency (EPA) must act now to protect communities from a highly toxic class of chemicals known as PFAS (per- and polyfluoroalkyl substances) that contaminate drinking water and groundwater. PFAS are associated with many serious illnesses, including cancers and reproductive disorders.

According to documents obtained through a Freedom of Information Act request by the Center for Science and Democracy, the Trump administration tried earlier in 2018 to suppress a government assessment of PFAS health impacts, calling it a "public relations nightmare." The health assessment was released after nearly 18,000 UCS supporters demanded its publication. Now we need federal decisionmakers to take the next step and regulate and clean up this toxic threat.

Act to protect our drinking water

There are several ways you can voice your concern about the need to protect our families and communities from PFAS:

Military families and communities are at especially high risk. A 2018 UCS analysis of 131 US military facilities showed that nearly all had significant PFAS contamination of groundwater or drinking water, some with levels over 100,000 times the safe limit as determined by the most recent draft scientific assessment from the Department of Health and Human Services. Millions of Americans live within three miles of a contaminated facility.

What are PFAS?

PFAS, also known as highly fluorinated chemicals, are a group of man-made substances used in products ranging from firefighting foam to microwavable popcorn packaging. When released into the environment, PFAS can travel far from their source, which heightens the chance of human exposure through drinking water or food. An analysis by the Environmental Working Group has shown that nearly 100 million Americans may have PFAS in their water.

PFAS health impacts

Research has tied PFAS exposure to a long list of health problems:

  • Various forms of cancer, including testicular and kidney cancer
  • Pregnancy-induced hypertension/pre-eclampsia
  • Liver damage
  • Increased cholesterol levels
  • Increased risk of thyroid disease
  • Decreased antibody response to vaccines
  • Increased risk of asthma diagnosis
  • Increased risk of decreased fertility
  • Small decreases in birth weight
