What is one of the potential consequences of improperly closing a well?

Improperly closing a well can lead to groundwater contamination, which is a significant environmental risk. When a well is not sealed correctly, contaminants from the surface, such as fertilizers, pesticides, or industrial pollutants, can seep into the aquifer that supplies drinking water. This contamination poses serious health risks to individuals relying on that water source.

Inadequate closure can create pathways that allow surface water and pollutants to enter the well. As groundwater serves as a critical resource for many communities, protecting it from contamination is essential for ensuring safe drinking water and maintaining the overall health of the ecosystem.

The other options, while relevant in different contexts, do not directly relate to the consequences of improper well closure. Increased water flow typically refers to hydrogeological conditions rather than the act of sealing a well. The reduction in local wildlife may occur due to broader environmental changes rather than well closure specifically. Higher water bills for consumers, while potentially influenced by water management practices, are not directly connected to the process of closing a well improperly.
