Abandoned Wells
A well that is no longer used or maintained can become a direct pipeline to groundwater, allowing for contaminated surface water to reach the water table. If there is an abandoned well on your property, you are legally responsible to ensure it is properly plugged by a licensed contractor. If you are planning on digging or drilling a new well on your property, the old one should first be properly closed to ensure there is no concern for surface water contamination of your groundwater table.
