What does decommissioning a well involve?

Decommissioning a well involves completely sealing it to prevent contamination of the surrounding environment, particularly groundwater. When a well is no longer in use, it is crucial to ensure that it does not serve as a pathway for contaminants to enter the aquifer or surrounding soil. This process usually includes filling the well with appropriate materials such as bentonite clay or cement to safely seal it off. Proper decommissioning is important for environmental protection and public health, as any failure to seal the well can lead to pollution and other serious consequences. Other options, such as regular maintenance, enhancing water quality, or extending the well's life, involve ongoing activities rather than the final closure and safeguarding of a non-operational well.
