Protecting our health from PFAS
What Are PFAS?
Per- and polyfluoroalkyl substances (PFAS) are an emerging class of chemicals with alarming health impacts. PFAS are a class of over 5,000 synthetic chemicals that have been produced since the 1940s. The unique physical and chemical characteristics of PFAS make them resistant to oil, water and temperature. While these properties make PFAS very useful chemicals for a wide variety of products, like Teflon, food packaging, rain-resistant clothing, and firefighting foam, they have contaminated water in many parts of Wisconsin, posing a threat to public health.
How Are PFAS Used?
One of the best-known uses of these chemicals is in firefighting foam. Military bases, airports, and firefighting training areas where these foams are used are among the first places where PFAS contamination has been identified in groundwater here in Wisconsin.
PFAS are also commonly used in textile manufacturing, plastic and paper products (e.g., fast food wrappers), household products (Teflon non-stick cookware), metal plating processes, medical products, personal care products (shampoos, dental floss), and other products.
How Do PFAs Affect Health?
One of the defining characteristics of PFAS chemicals is the carbon-fluorine chain. The carbon-fluorine bond is very strong, so PFAS do not break down easily, leading some to refer to PFAS as “forever chemicals.” This strong bond means that once PFAS get into the environment, or our bodies, they stick around and accumulate over a lifetime. Researchers are still working to better understand the health effects of PFAS. So far studies have shown that there can be multiple health effects from PFAS exposure:
Based on the current state of knowledge, the primary way people are exposed to PFAS is through contaminated drinking water and eating food containing PFAS (PFAS can bioaccumulate in fish and wildlife) or contaminated by its packaging. Inhalation and incidental ingestion of household dust is also a potential pathway, particularly for younger children.
PFAS Contamination in Wisconsin
This map shows known PFAS contamination sites around the state. PFAS compounds have been detected in drinking water at levels up to 1,900 parts per trillion (ppt), almost 100 times the proposed health-based standard of 20 ppt.

A Crisis of Contamination
Marinette and Peshtigo are communities in Wisconsin struggling with PFAS contamination. In this video by Clean Wisconsin, we hear from local residents, elected officials, and state agency staff about the impacts of PFAS pollution that has left many with contaminated drinking water.
Recently, La Crosse area residents are discovering PFAS in their drinking water, many over the state’s recommended limit of 20 parts per trillion, from firefighting foam used by the city’s fire department.
With the many challenges facing Wisconsinites—including unsafe drinking water, impacts from climate change, and living through a global pandemic—the governor’s budget proposal includes important initiatives to both help Wisconsin families and sustain a strong economy.
Gutting of Wisconsin’s only protections from PFAS contamination through sham process “an absolute disgrace”
“By gutting these rules, JCRAR is doing the bidding of industry PFAS users. To add insult to injury, the hearing completely cut out the people who are dealing with the health consequences of contaminated drinking water and demanding action from their lawmakers.”
