The RL DNR Water Resources Program seals abandoned wells at no cost while funding is available. We currently have funding to seal about 20 drilled wells and some additional funding to fill dug wells. An abandoned well is any well that is no longer used as a water supply. Old, unused, and uncapped wells can pollute your drinking water. They connect to the same aquifer (underground water source) as other wells nearby and provide a pathway for harmful substances to enter including animals, bacteria, and harmful chemicals. If you think you have an abandoned well, contact Rick Barrett for a free inspection.
