Hydrogeology

Hydrogeology is the area of geology that studies the distribution and movement of groundwater in the soil and rocks of the Earth's crust, often within geological formations known as aquifers. As a sub-discipline of hydrology, it investigates the physical and chemical interactions between water and the surrounding earth materials, examining how groundwater is recharged, flows through the subsurface, and discharges to the surface. This field is critical for managing water resources, as it provides the scientific basis for locating wells, preventing and cleaning up groundwater contamination, and assessing the environmental impacts of water extraction.
