For more than 50 years, Clean Wisconsin has been working to preserve and protect Wisconsin’s clean water, clean air and natural heritage. Everyone deserves to live in a healthy community. Together, we can protect the places we love.

PFAS Pollution in Wisconsin

Everyone should be able to eat the fish they catch and drink the water flowing from their taps. But in Dane County and dozens of other communities across the state, PFAS contamination is putting our waterways at risk. These chemicals surround us – in carpeting and upholstery, clothes, shoes, firefighting foam, fast food wrappers, ski wax, non-stick pots and pans, and the list goes on. Clean Wisconsin is pushing for meaningful progress at all levels.

Wisconsin’s First Solar Neighborhood

A look inside the first and so-far *only* net-zero electricity solar neighborhood in the state of Wisconsin! All of these New Berlin, Wis. homes are certified through Focus on Energy’s New Home Certification Program. But there is so much more work to be done. We need more state & federal investment to make solar more accessible and affordable for everyone. Now is the time to fight the climate crisis and build a clean energy future.

Vicious Cycle: The Struggle for Clean Water

More than two-thirds of Wisconsinites use groundwater as their drinking water source, but what happens if that water is contaminated? Over 80,000 private wells across the state are contaminated with high levels of nitrates, limiting resident’s access to clean drinking water and putting their health at risk. Homeowners, like Steven Shoemaker and Elisabeth Minich, are then on the hook for thousands of dollars to try and clean the water, but they say it should not be their responsibility.
