water stored below the Earth's surface inside the pores (void space) of geologic materials called aquifers. Groundwater may be fresh or saline.
Water from a subsurface water source.
Groundwater is that subsurface water contained in the interconnected pore spaces below the water table of an aquifer. Groundwater will occur where there is an impermeable subsurface barrier that allows water flowing through the unsaturated zone to be collected and stored within the interconnected pore spaces at depth. This impermeable barrier may be bedrock or an impermeable layer of rock. Once collected in the saturated zone, groundwater will flow from areas where the water table is highest toward areas where it is lowest. This percolation of water through the saturated zone is powered by gravity. Eventually, percolating water may leave the groundwater system and be discharged into streams or other surface water bodies.

A term used to describe the water which is found below ground. This water, which in most cases is derived from water seeping into the ground, is found in those geological formations which have a certain porosity. Groundwater is commonly abstracted through wells and is a major source of drinking water, irrigation water and industrial water in many parts of the world. Relative to surface waters, groundwater moves extremely slowly - a flow of meters a day is considered very fast. Because of this, any contaminants which enter groundwater are flushed away only very slowly. This fact, together with its importance as a source of water, makes contamination of groundwater a very critical environmental issue in many circumstances.
