Black Earth drinking water comes from groundwater wells. Based on the most recent monitoring data, 10 contaminants have been detected in the water supply, including Lead, Nitrate, Copper, Total Trihalomethanes, and 6 others. PFAS testing has been conducted with no detections. Water hardness is 304 mg/L (very hard), which can cause scale buildup in appliances and reduce soap effectiveness.

Detection does not necessarily mean unsafe levels. See individual reports for concentrations and EPA limits.
Black Earth tap water meets EPA legal standards (Maximum Contaminant Levels). However, 2 contaminants are present above independent health guidelines, which are often stricter than legal limits. 10 contaminants have been detected in the water supply, including Lead, Nitrate, Copper, Total Trihalomethanes, Haloacetic Acids (HAA5). 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 Black Earth water?
Monitoring has detected 10 contaminants in Black Earth's water supply: Lead, Nitrate, Copper, Total Trihalomethanes, Haloacetic Acids (HAA5), Nickel, Selenium, Fluoride, Antimony, Barium. 2 exceed health guidelines. See individual system reports for concentrations relative to EPA limits.
Does Black Earth water have PFAS?
Black Earth's water has been tested for PFAS compounds with no detections. Testing was conducted as part of the EPA's Unregulated Contaminant Monitoring Rule (UCMR5) program.
Is Black Earth water hard?
Yes. Black Earth water has a hardness of 304 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 Black Earth get its drinking water?
Black Earth'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. Black Earth is served by one water system: BLACK EARTH WATERWORKS.
