Does Antigo water have PFAS?
Yes. 4 PFAS compounds have been detected in Antigo's water supply at trace levels. PFAS are sometimes called "forever chemicals" because they do not break down in the environment. The EPA has set Maximum Contaminant Levels for several PFAS compounds. View the detailed report for specific concentrations.
Is Antigo water hard?
Yes. Antigo water has a hardness of 200 mg/L (very hard). Hard water is not a health concern but can cause scale buildup in water heaters and appliances, reduce soap effectiveness, and leave mineral deposits. Water softeners or conditioning systems can address hardness.
Where does Antigo get its drinking water?
Antigo's drinking water comes from groundwater wells that draw from underground aquifers. The water is treated and tested according to Wisconsin DNR and EPA requirements before distribution. Antigo is served by 2 water systems, the largest being ANTIGO WATERWORKS (serving 7,780 people).
