What is a recovery well constructed for?

A recovery well is specifically designed for the purpose of extracting contaminated or undesirable groundwater from an aquifer so that it can be treated and managed properly. This process is crucial in environmental remediation efforts, where the goal is to minimize the impact of pollutants on water supplies and maintain groundwater quality.

While other options mention important water management practices, they do not align with the primary function of a recovery well. For instance, enhancing flood control measures focuses on managing surface water rather than addressing groundwater contamination. Providing water for agricultural use typically involves sourcing clean water, not recovering or treating undesirable groundwater. Similarly, stabilizing soil erosion refers to preventing soil loss rather than groundwater extraction. Thus, the role of a recovery well is distinctly linked to its function in treating and reclaiming compromised groundwater.
