The MDHHS Care for MiWell Sampling Project assesses water quality from Michigan’s private wells and helps Michigan residents understand the quality of their well water.
Drinking water can become contaminated through natural and human activity. Some contaminants can be harmful to your health if you are exposed to certain levels.

The green area on this map shows the area (census tract) in each county in Michigan randomly selected for the project using a statistical method.
Purpose of the Care for MiWell Sampling Project
The Care for MiWell Sampling Project provides free drinking water testing and education for randomly selected private well owners across Michigan. This can help residents identify conditions that impact their home’s drinking water and provide data-backed guidance to help reduce risks from potential contaminants in well water.
