What is the goal of sealing during well construction or development?

The goal of sealing during well construction or development is to create a permanent barrier against groundwater movement. This sealing process is crucial for preventing contamination and maintaining the integrity of the well. By ensuring that water does not flow freely between different aquifers, sealing helps protect the quality of the groundwater. It also minimizes the risk of surface pollutants entering the well. Effective sealing is essential for preserving the specific water quality from the aquifer being tapped, as well as maintaining the hydraulic properties of the well. The goal is to provide a reliable supply of water while safeguarding it from environmental contaminants and ensuring the separation of aquifer layers.
