This is some info on groundwater
Ground water is water held underground in the soil or in pores and crevices in rock. but lets look deeper.
Groundwater is the water found underground in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through parts of soil, sand and rocks called aquifers. The area where water fills the aquifer is called the saturated zone (or saturation zone). The top of this zone is called the water table. The water table may be located only a foot below the ground’s surface or it can sit hundreds of feet down.
Aquifers are typically made up of gravel, sand, sandstone, or fractured rock, like limestone. Water can move through these materials because they have large connected spaces that make them permeable. The speed at which groundwater flows depends on the size of the spaces in the soil or rock and how well the spaces are connected. Groundwater can be found almost everywhere. The water table may be deep or shallow; and may rise or fall depending on many factors. Heavy rains or melting snow may cause the water table to rise, or heavy pumping of groundwater supplies may cause the water table to fall.
Groundwater is found in vast quantities filling the spaces between grains of soil or rock; it slowly flows through aquifers; it connects with rivers, streams, lakes and wetlands; it feeds trees and vegetation. Australia is a very old continent, and much of its groundwater is tens of thousands, even hundreds of thousands of years old.
For example, the Great Artesian Basin in central Australia is the largest aquifer of its kind in the world, covering 22% of Australia, and containing water that is more than a million years old.
Groundwater supplies are replenished, or recharged , by rain and snow melt that seeps down into the cracks and crevices beneath the land's surface.
