How do you know if your water utility has tested for PFAS?
Some communities—including Milwaukee, Madison, Marinette, Peshtigo, Rhinelander, and La Crosse—have tested for PFAS, but most public water utilities in Wisconsin have not conducted comprehensive PFAS testing.
Milwaukee voluntarily tests its water supply for more than 40 PFAS compounds. PFAS levels are below the Department of Health Services' recommended health advisory limit of 20 parts per trillion. Find the most recent test results here. The Milwaukee Water Utility sells water to other communities. Municipalities that receive 100% of their water from the Milwaukee Water Utility include Brown Deer,Butler, Greendale, Menomonee Falls, Mequon, New Berlin, Shorewood, Wauwatosa and West Allis.

Madison Water Utility first began in-depth testing for a broad spectrum of PFAS chemicals at all city wells in 2019 at the urging of community members who petitioned the Water Utility Board for comprehensive monitoring. Learn more here.
PFAS have been detected in two City of La Crosse municipal wells and in groundwater samples near the La Crosse Regional Airport. The La Crosse Water Utility has removed the two wells from production. Learn more here.
Two of Rhinelander’s five municipal wells are currently offline after the discovery of high levels of PFAS. Learn more here.
A municipal well can be sampled for about $600. That's a small price to pay to ensure that a community isn't drinking contaminated water.
