The following is a consumption advisory regarding the municipal water supply. This notice affects approximately 5,000 households and businesses that currently use the municipal water supply. In addition, the nearly 1,500 properties with private wells may be affected.
The City is dedicated to providing clean and safe drinking water to residents. Testing by the Minnesota Department of Health (MDH) shows the City's municipal water supply continues to meet all Safe Drinking Water Act standards.
MDH conducted additional testing in 2019 as part of a study of unregulated contaminants. This testing showed that some of our wells have manganese levels above MDH's recommended health guidelines.
Manganese is a naturally occurring element found in rocks and soil and is often found in Minnesota ground and surface water. Your body needs some manganese to stay healthy, but too much can be harmful. Learn more by visiting the MDH webpage and searching for Manganese in Drinking Water.
Manganese is unregulated and does not have an enforceable standard. However, the MDH recommended health guidelines are:
If you have an infant who drinks tap water or drinks formula made with tap water, a safe level of manganese in your water is 100 parts per billion (ppb) or less.
If you have an infant who never drinks tap water or formula made with tap water, a safe level of manganese in your water is 300 ppb or less.
If everyone is more than one year old, a safe level of manganese in your water is 300 ppb or less.
The City requested testing from MDH to better understand manganese levels for all City wells
