What does well abandonment refer to?

Well abandonment refers specifically to the process of closing a well that is no longer in use. This process is crucial to prevent contamination of groundwater resources and to ensure the safety of the surrounding environment. An abandoned well can pose various risks, including subsurface water pollution or physical hazards if not properly sealed or decommissioned.

The proper abandonment of a well involves following specific regulatory guidelines that can include filling the well with appropriate materials, capping it securely, and potentially notifying local authorities. This ensures that the well cannot inadvertently become a pathway for contaminants to enter the groundwater system.

Other options, while related to well management, do not accurately define well abandonment. For instance, drilling a new well to replace an old one does not involve the decommissioning of the existing well. Reducing the flow rate of an existing well pertains to managing the well’s output rather than closing it. Converting a well into a monitoring well involves changing its function rather than taking it out of service entirely.
