What is Groundwater?

When rain falls to the ground, the water does not stop moving. Some of it flows along the surface in streams or lakes, some of it is used by plants, some evaporates and returns to the atmosphere, and some sinks into the ground. Imagine pouring a glass of water onto a pile of sand . Where does the water go? The water moves into the spaces between the particles of the sand.

Groundwater is water that is found underground in the cracks and spaces in soil, sand, and rocks. The area where water fills these spaces is called the saturated zone. The top of this zone is called the water table… just remember the top of the water is the table. The water table may be only a foot below the ground’s surface or it may be hundreds of feet down.
