LANSING, Mich. - As the summer season is drawing closer, the Michigan Department of Health and Human Services (MDHHS) is reminding everyone to avoid foam on Michigan lakes and rivers known to have high levels of PFAS.

Health advisories for foam exist on these waterbodies:

  • Van Etten Lake, Oscoda.
  • Lake Margrethe, Grayling.
  • Rogue River, Rockford.
  • Thornapple River, Grand Rapids.
  • Huron River, Southeast Michigan.

Foam on these bodies of water have much high amounts of PFAS than the water and health officials say swallowing the foam could be a health risk. Swimming or bathing in the water containing PFAS isn't a health concern because the amount of PFAS is typically low compared to the foam. 

It is recommended that if you do come in contact with foam containing PFAS, you rinse off. The MDHHS says although current studies indicate PFAS does not move easily through the skin, the recommendation still stands.

The industrial compounds have been used in some firefighting foam, waterproofing, carpeting and other products. They can get into drinking water when products containing the chemicals are spilled onto the ground or in lakes or rivers.
