Groundwater

water located beneath the ground surface

Groundwater (or ground water) is water located below the ground surface. Groundwater starts as rain (or other precipitation), and flows under ground for long periods of time through aquifers. Groundwater flow returns to the surface again through springs and rivers. Groundwater is an important part of the water cycle.

Groundwater flow through aquifers

People bring groundwater to the surface by digging or drilling wells below the surface. They bring up water from the aquifer and use it for irrigation and other purposes.
