What is the primary purpose of geology in relation to groundwater?

The primary purpose of geology in relation to groundwater is to identify potential aquifer formations. Knowledge of geological formations is essential for locating aquifers, which are underground layers of water-bearing rock or sediment that can store and transmit groundwater. Geologists study the characteristics of different rock types, their porosity, permeability, and the structure of the earth's crust to determine where groundwater is likely to be found, how it moves through the subsurface, and the overall capacity of aquifers.

This geological understanding helps in planning for groundwater extraction, managing water resources, and assessing the sustainability of groundwater supply. Proper identification of aquifers is crucial for drilling wells and ensuring a reliable source of water for various uses, including agricultural, industrial, and municipal needs.
