Abandoned Wells

Abandoned Wells and Groundwater Contamination

Wells that are not being used for consumption or irrigation purposes are considered abandoned. An abandoned well can be a potential threat to health, safety, and the environment by contaminating the groundwater, which provides 100% of drinking water for Washington County residents. 

Sealing Abandoned Wells

Unless you have a Well Maintenance Permit, Minnesota law (statues 103I.301) requires the sealing of abandoned wells. Well sealing must be completed by a licensed well contractor
