Why unused wells must be plugged

Minnesota health officials say every unsealed unused well is a safety, health and environmental threat, and children and small animals can fall into open wells.

The Missouri Department of Natural Resources says abandoned wells are a physical hazard and a direct channel for surface contamination to reach aquifers.

Texas A&M AgriLife Extension notes that under Texas law the landowner must plug abandoned wells and is liable for contamination or injury from an unplugged well.

In Texas, a well is considered abandoned if it has not been used for 6 consecutive months, unless its equipment is in good condition or it is capped.

Tennessee requires wells taken out of service to be closed by a licensed water well driller to state standards.

EPA advises hiring a certified well driller for new well construction, changes, or abandonment and closure.
