All three systems supply drinking water that meets required federal and state drinking water standards. Pierre's water contains manganese that causes brown staining; water produced by Mid-Dakota and Mni Wiconi does not contain manganese. Additionally, the concentrations of calcium and magnesium are approximately 30% higher in Pierre's water supply than in the water produced by Mid-Dakota and Mni Wiconi, making Pierre's water harder than the water supplied by the other systems.

The treatment process will remove iron and manganese from the treated water. Here's what that means for you.
Yes. The Drinking Water Treatment Facility will remove the minerals from Pierre's water that currently differentiate Pierre's water from the water produced by the Mid-Dakota or Mni Wiconi systems.
Yes. The treatment process will remove the minerals from the water that can cause water discoloration.
Over the past few decades, the well water quality has deteriorated, exhibiting increasing concentrations of minerals, hardness, and sulfate. This deteriorating water quality trend is likely to continue as the wells age.
Pierre’s water contains manganese and iron that forms dark deposits when it evaporates.
Yes. The treatment process would remove the minerals that cause staining.
No. Conversely, treated water tends to have fewer negative impacts on plumbing fixtures.
