This may lead to increased concentrations of these metals in drinking water which can cause health concerns. See our fact sheets on pH
At pH levels of less than 7.0 corrosion of water pipes may occur
Typical groundwater pH values in Wisconsin range from 6.5 to 8.5. Sources: Low values are most often caused by lack of carbonate minerals in the aquifer.
All drinking water sources have potential to contain microorganisms such as bacteria

Acidic waterbodies can negatively impact potable and industrial water supplies and can cause excessive corrosion in metal and concrete infrastructure (Fox

Acidity or low pH is caused by natural geological conditions in the area. The optimal pH range for drinking water is 6.5 – 8.5 as established by the EPA.
