Wisconsin Fights EPA's PFAS Rollback: What You Need to Know in 2025

What's happening with drinking water standards right now?

Wisconsin's Department of Justice is joining other states and environmental groups to oppose a proposal by the U.S. Environmental Protection Agency (EPA) that would weaken limits on PFAS chemicals in drinking water. The action marks a significant pushback against a federal regulatory step that could allow higher levels of these persistent pollutants in the water you drink at home and in your community.

PFAS—per- and polyfluoroalkyl substances—are synthetic chemicals used in countless industrial and consumer products, from nonstick cookware and food packaging to firefighting foam and water-resistant textiles. Once released into the environment, they don't break down naturally, which is why scientists call them "forever chemicals." They've been detected in the drinking water supplies of millions of Americans.

Why is Wisconsin's government opposing this EPA move?

The EPA established drinking water limits for PFAS in 2023, setting enforceable standards for two common PFAS chemicals: PFOA and PFOS. Wisconsin's DOJ, along with a coalition of other states, environmental organizations, and public health advocates, argues that rolling back these standards would reverse progress on protecting public health and the environment.

According to Wisconsin's position, the existing standards represent sound science and are necessary to protect residents from exposure to chemicals associated with health concerns including kidney disease, thyroid dysfunction, reproductive issues, and immune system effects. The state contends that weakening these limits would undermine efforts already underway in Wisconsin to address PFAS contamination in groundwater and surface water.

Who is affected by PFAS in Wisconsin?

Wisconsin has documented PFAS contamination in multiple communities. The chemicals have been found in drinking water supplies serving both urban and rural areas, as well as in groundwater near industrial sites, airports, and military installations where fluorinated firefighting foam has been used. Residents in affected areas face ongoing exposure through tap water, and some have already been advised to use alternative water sources or install special filters.

Beyond Wisconsin, millions of Americans nationwide have detectable PFAS levels in their blood, according to CDC data. If the EPA's standards are rolled back, more communities could face higher allowable contamination levels in their drinking water—affecting everyone from families relying on municipal water systems to small communities served by private wells.

Why does this matter for your health and your home?

The EPA's 2023 drinking water standards represent the first-ever federal limits on PFAS in drinking water. Before this, there was no federal requirement to test for or remove these chemicals, and regulations varied widely by state. The standards set maximum contaminant levels (MCLs) that water utilities are required to meet.

If these standards are weakened or rolled back, water systems would no longer be required to monitor and reduce PFAS to the same degree. This could mean:

• Higher PFAS concentrations allowed in your tap water
• Less frequent testing for contamination in your community
• Reduced incentive for water utilities to install treatment systems
• Greater financial burden on households to install private filtration systems

Research has associated PFAS exposure with health effects including elevated cholesterol, liver damage, thyroid disease, and reduced vaccine response in children. While more research is ongoing, these associations have prompted public health agencies to recommend limiting exposure.

What can you do right now?

Check your local water: Visit your water utility's website or contact them directly to find out whether PFAS has been detected in your community's drinking water supply. Many utilities publish annual water quality reports that include testing results.

Know your options: If PFAS is present in your area, you have several choices: use bottled water for drinking and cooking, install a point-of-use filter (carbon-based filters can reduce PFAS), or switch to a water system that treats for PFAS removal. The PFAS water filter finder can help you identify appropriate filtration options based on your situation.

Stay informed: Monitor updates from your state health department and water utility regarding PFAS standards and any changes to federal regulations. Wisconsin residents can check the Wisconsin Department of Natural Resources website for state-level PFAS information and actions.

Support accountability: If you're concerned about PFAS in your water, contact your elected representatives at the local, state, and federal level. Public comment periods on EPA proposals offer opportunities for citizens to weigh in on regulatory decisions.

Bottom Line

Wisconsin's opposition to EPA's PFAS rollback reflects growing concern among public health officials and states about protecting drinking water from these persistent chemicals. While federal standards are still being finalized, the regulatory battle underscores why it's important for consumers to understand their own water quality and take steps to reduce PFAS exposure where needed. Staying informed and being proactive about testing and filtration puts you in control of a health issue that ultimately affects your household's water supply.

Three Questions About PFAS and Your Water

Are PFAS chemicals in my tap water?

PFAS has been found in drinking water supplies across the U.S., including multiple communities in Wisconsin. The only way to know if your water is affected is to check your local water utility's most recent water quality report or contact them directly. If you rely on a private well, you may need to arrange testing through a certified laboratory.

What does "rolling back" standards mean for me?

If the EPA weakens its PFAS limits, water utilities would be allowed to deliver water with higher PFAS concentrations without violating federal requirements. This could increase your potential exposure and might mean your utility has less obligation to test for or treat these chemicals.

Are carbon water filters effective against PFAS?

Certain activated carbon filters can reduce PFAS in drinking water, though effectiveness varies by filter type and PFAS compound. Reverse osmosis and ion-exchange systems are also used. See our methodology for information on how different filter technologies work, and use the water filter finder to match treatment options to your specific water quality concerns.
