What are PFAS?
PFAS (Perfluoroalkyl and polyfluoroalkyl substances) are a large group of human-made chemicals. They can affect your health at low levels and can accumulate in your body over time. They’ve been used for over 50 years and are in many everyday products. These chemicals don’t break down easily and are now common in our environment. PFAS are being found in more and more drinking water supplies, including in Dane County. It’s important to limit your exposure as much as possible to protect your health.

Communities in Dane County have tested their water through the DNR. Visit the DNR website  and click “PFAS Sampling Info” under “Layer Controls.” Click on the circle next to the name of the municipality to find out the results.
