Beware the Bubbles: Toxic Foam Threatens Michigan Waterways

Michigan residents enjoying their state's beautiful lakes and rivers this summer might encounter an unwelcome sight - toxic foam. While natural foam can sometimes appear on water bodies, the recent increase in reports raises concerns about Per- and Polyfluoroalkyl Substances (PFAS) contamination.

Understanding PFAS and the Foam Threat

PFAS, also known as "forever chemicals," are man-made chemicals used in various products like firefighting foams, non-stick cookware, and stain repellents. These chemicals are highly persistent in the environment and can accumulate in waterways. When this happens, PFAS can concentrate in foam bubbles, reaching levels thousands of times higher than the surrounding water.

Health Risks Associated with PFAS Foam

While casual contact with PFAS foam on the skin is unlikely to cause immediate harm, health officials warn against ingesting it. Children playing in the water are particularly at risk. Long-term exposure to PFAS has been linked to various health problems, including cancer, thyroid issues, and immune system complications.

Distinguishing Between Natural and PFAS Foam

Natural foam on lakes and rivers is typically off-white or brown, accumulates in bays or eddies, and may have an earthy or fishy smell. PFAS foam, on the other hand, can be more persistent and may appear in rainbow colors due to industrial pollutants. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) offers a helpful brochure to distinguish between the two https://www.michigan.gov/pfasresponse/investigations/pfas-foam.

What to Do if You Encounter Foam

If you see foam on a Michigan waterway, it's best to avoid contact altogether. Here are some additional tips:

• Keep children and pets away from the foam.
• Do not swim, boat, or fish in areas with foam.
• Report sightings of foam to the Michigan Department of Environment, Great Lakes, and Energy (EGLE) at 1-800-662-9278.

Taking Action: Addressing PFAS Contamination

The presence of PFAS foam highlights the ongoing issue of PFAS contamination in Michigan's water. Residents are encouraged to stay informed about PFAS testing initiatives and advocate for stricter regulations on these harmful chemicals.

Enjoying Michigan's Waterways Safely

By following these precautions and staying informed, Michigan residents can continue to enjoy the state's beautiful waterways while minimizing the risks associated with PFAS foam. Remember, a little caution can go a long way in protecting your health and the health of your loved ones.
