For the nearly 40 million Americans who own wells, there is no better time to act to protect drinking water quality than on Protect Your Groundwater Day (which was held September 5), according to the National Ground Water Association. Two key actions well owners can take to protect groundwater are to make sure 1) there is a proper well cap on top of the well and 2) that any abandoned wells or boreholes on their property are properly plugged (i.e., decommissioned). This is the subject of the association’s Cap It, Plug It! video ( If an active water well is not capped properly, or if an abandoned well is not plugged properly, it can be a direct pathway for contamination from above the ground to the groundwater used by well owners for drinking. Private well owners are responsible for monitoring the ongoing quality of their drinking water.
