Which factor is NOT considered for the permanent abandonment of a well?

When determining the permanent abandonment of a well, various factors must be evaluated to ensure that the well is rendered completely inactive and poses no risks. Structural integrity is vital to assess whether the well casing and surrounding materials will remain stable and not collapse or create safety hazards. Similarly, continued usability takes into account whether the well could potentially be used in the future, influencing how it should be decommissioned. The health hazard potential is critical, as it helps evaluate whether the well could pose a risk to groundwater quality or public health if left abandoned.

The depth of the well, while it can be relevant in some contexts, is not a direct consideration for permanent abandonment. The abandonment process focuses more on ensuring safety, structural integrity, and environmental protection, rather than solely the physical dimensions of the well itself. Thus, among the options, depth is the factor that does not directly contribute to the decision-making process regarding the abandonment of a well.
