Where is the PFAS Contamination in Michigan?

Teflon nonstick pans are a source of PFAS. The PFAS contamination in Michigan reach widespread appeal in 2019.

The recent discovery of PFAS contamination in Michigan isn’t the first case where our residents realized they’d been consuming contaminated water. In fact, in the Rockford, Grand Rapids and Kalamazoo areas alone, there are 20+ bodies of water that have PFAS contamination.
Contaminated areas sprawl across the entire state of Michigan, from Benton Harbor to Otter Lake in Houghton County. Most of the Great Lakes contain a measurable amount of PFAS.

There are four different PFAS contaminations:

1. PFAS Fishing Advisories
These bodies of water have tested the fish and warn fishers about consuming the fish in these bodies of water as they have tested positive for PFAS. For a full list of PFAS Fishing Advisories click here.

2. Toxic Foam Sites
PFAS compounds reveal themselves in the form of foam in our rivers and lakes. Since PFAS compounds don’t break down, the biggest concern about this contamination is that it will stay in the environment for up to 25 years.

3. Water and Fish Testing
Fish in these bodies of water are collected and tested to determine if fish consumption advisory is needed.

4. Identified Contaminated Sites
These are lakes, rivers, and resident wells that have been tested and labeled as a contaminated site.

As we discussed in our first blog on our series, PFAS is more common than you may think. Probably the most recognizable brand name to use this material is Teflon, however, they’re not the only offender. It’s popular in cookware because of its resistance to oil, grease, and water. Fast food wrappers, pizza boxes, water-resistant fabrics, and fire-fighting foam also contain PFAS as an ingredient.

While manufacturers have agreed to stop producing two forms of PFAS, they’re a lingering issue because they take a long time to break down once in the environment.


The reasons PFAS are harmful is still a bit of a mystery since there has been little research on it. However, PFAS has been linked to health issues such as cancer, low birth weight, thyroid disease, high cholesterol and effects on the immune system.

If your water has tested positive for PFAS contamination, stop using that water for drinking, cooking, brushing your teeth, and watering your pets immediately. We strongly advise to drink bottled water until you can get a system with a p473 Certified PFAS filter or a high-quality reverse osmosis system installed in your home.

Wishing you and your family a safe, healthy, and happy spring!
