Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations.

- Groundwater

A well is an excavation or structure created in the ground by digging, driving, or drilling to access liquid resources, usually water.

- Well

The oldest and most common kind of well is a water well, to access groundwater in underground aquifers.

- Well

Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells.

- Groundwater

Small portions of water occur as groundwater (1.7%), in the glaciers and the ice caps of Antarctica and Greenland (1.7%), and in the air as vapor, clouds (consisting of ice and liquid water suspended in air), and precipitation (0.001%).

- Water

Water supply facilities include water wells, cisterns for rainwater harvesting, water supply networks, and water purification facilities, water tanks, water towers, water pipes including old aqueducts.

An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt).

Groundwater from aquifers can be extracted using a water well.

Hydrogeology (hydro- meaning water, and -geology meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust (commonly in aquifers).

Hydrogeology is an interdisciplinary subject; it can be difficult to account fully for the chemical, physical, biological and even legal interactions between soil, water, nature and society.
