Preventing
PFAS Exposure

What are PFAS?

Per- and polyfluoroalkyl substances (PFAS) are a large group of synthetic chemicals often used for their nonstick and grease- and water-resistant properties. PFAS contamination in drinking water and consumer products accumulates in humans and is linked to several health concerns. Often, PFAS are referred to as forever chemicals.

Why does PFAS matter?

Only a small percentage of over 5,000 PFAS chemical variations have been tested for toxicity. Those tested have been linked to health conditions including low birth weights, immune system impairments, decreased fertility, and increased risk of some cancers. In 2006 some major US manufacturers agreed to phase out the use of these chemicals, but many consumer goods still contain PFAS.

TODAY PFAS ARE FOUND IN:
Nonstick cookware
Waterproof clothing
Stain-resistant Furniture and Carpet
Personal Care Products
Food Packaging
Firefighting Foam

PFAS Exposure

PFAS can be found in all areas of our lives. Most often, people consume PFAS in our water and food. When PFAS are spilled or released onto the land, the chemicals easily travel into groundwater. Lakes and rivers in the watershed become contaminated, as do fish and wildlife. PFAS in groundwater then impact municipal drinking water supplies.

Exposure can also occur by simply using products containing the chemicals. When PFAS are present in cooking and food packaging products they leach out of these products and into our food.

There is a growing awareness that under-resourced communities are more likely to live close to PFAS contamination sites. Public health officials worry that the immunity response may be compromised in populations with high PFAS levels, limiting the effectiveness of vaccines.

Initiatives to Prevent and Treat Contamination

Preventing PFAS from entering landfills and wastewater treatment plants is cheaper and more effective than trying to clean them up after they are in the environment and our bodies. Conservation Minnesota is working to advance several bills designed to address contamination prevention and cleanup of PFAS.

Define PFAS as a Hazardous Substance (HF 78 & SF156)

The legislature is working on a bill that would help the state with cleanup efforts by defining PFAS as hazardous substances under the state superfund law. The bill would also direct the MPCA to establish a water-quality standard for PFAS.

Ban PFAS in Food Packaging (HF79 & SF70)

This bill would ban the manufacture, distribution, and sale of food packaging containing PFAS chemicals beginning in 2023.

Supporting Governor Walz’s Budget Recommendations to Address PFAS

Working with the Minnesota Pollution Control Agency, the Governor has set forth initiatives to help protect Minnesotans from the impacts of PFAS contamination. They include:

  • Identifying sources of PFAS in the environment by providing more agency funding.
  • Protecting Minnesota families from fish contaminated with PFAS by funding a two-year study of the extent of contamination in our fish populations.
  • Evaluating the extent of PFAS contamination in landfills, compost facilities, and wastewater treatment facilities and finding ways to protect our drinking water and farmlands from these sources of contamination.
  • Reducing PFAS in wastewater and landfills to protect drinking water and farmlands.
