groundwater
Water beneath soil
Groundwater is water held underground in soil and rock formations, accessed through wells or emerging as springs.
It supplies drinking water for roughly half the world's population and irrigates much of global agriculture.
The water table marks where groundwater begins.
Groundwater levels have dropped dramatically due to overpumping.
