Is there water under the ground?

Yes. The main body of subsurface water is found in the saturated zone of aquifers. Aquifers can be only a few feet below the surface or more than a thousand feet deep. Aquifers are the primary source of drinking water in arid and semi-arid parts of the United States where the amount of surface water (water in streams, lakes, and reservoirs) is limited. There is also subsurface water in soils (which is mostly used by plants), and in the zone found between the soil zone and the saturated zone of aquifers. This zone is called the unsaturated zone. The unsaturated zone includes a layer directly above the aquifer called the capillary fringe where water in the saturated zone is drawn upward by capillary action.
