Hilbert drinking water comes from groundwater wells. Based on the most recent monitoring data, 15 contaminants have been detected in the water supply, including Lead, Nitrate, Arsenic, Copper, and 11 others. PFAS compounds have been detected at trace levels in Hilbert water. Water hardness is 478 mg/L (very hard), which can cause scale buildup in appliances and reduce soap effectiveness.

Frequently asked questions

Is Hilbert, WI tap water safe to drink?
Hilbert tap water meets EPA legal standards (Maximum Contaminant Levels). However, 4 contaminants are present above independent health guidelines, which are often stricter than legal limits. 15 contaminants have been detected in the water supply, including Lead, Nitrate, Arsenic, Copper, Radium. View the detailed report for each water system to see specific levels and how they compare to both legal limits and health guidelines.
What contaminants are in Hilbert water?
Monitoring has detected 15 contaminants in Hilbert's water supply: Lead, Nitrate, Arsenic, Copper, Radium, Uranium, Gross Alpha Radiation, Total Trihalomethanes, Haloacetic Acids (HAA5), Nickel, Mercury (inorganic), Chromium (total), Barium, Fluoride, Lithium. Additionally, 1 PFAS compounds have been detected at trace levels. 4 exceed health guidelines. See individual system reports for concentrations relative to EPA limits.
Does Hilbert water have PFAS?
Yes. 1 PFAS compounds have been detected in Hilbert'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 Hilbert water hard?
Yes. Hilbert water has a hardness of 478 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 Hilbert get its drinking water?
Hilbert'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. Hilbert is served by one water system: HILBERT WATERWORKS.
