What contaminants are in Slinger water?
Monitoring has detected 20 contaminants in Slinger's water supply: Lead, Nitrate, Arsenic, Copper, Radon, Radium, Uranium, Gross Alpha Radiation, Total Trihalomethanes, Haloacetic Acids (HAA5), Nickel, Selenium, Mercury (inorganic), PFHpA (Perfluoroheptanoic Acid), Nitrite, Fluoride, Barium, Methyl Tert Butyl Ether, Pfhxa, Pfpea. Additionally, 7 PFAS compounds have been detected at trace levels. 3 exceed health guidelines. See individual system reports for concentrations relative to EPA limits.
Does Slinger water have PFAS?
Yes. 7 PFAS compounds have been detected in Slinger'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 Slinger water hard?
Yes. Slinger water has a hardness of 510 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 Slinger get its drinking water?
Slinger'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. Slinger is served by one water system: SLINGER WATER UTILITY.
