Answer: The principal reason for the increase of groundwater use is the increasing population. Urbanization and pollution have both contributed to an increase in the use of groundwater. Polluted rivers lakes and springs are no longer viable sources of groundwater. Urbanization has concentrated large populations in areas that might not have direct access to surface water or that might have a larger demand for freshwater than surface water can supply.
Why has groundwater use increased over time?

Direct effects. An irrigation scheme draws water from groundwater rivers lakes or overland flow and distributes it over an area. Hydrological or direct effects of doing this include reduction in downstream river flow increased evaporation in the irrigated area increased level in the water table as groundwater recharge in the area is increased and flow increased in the irrigated area.

Tue Jan 22 2008 13:30:00 GMT-0500 (Eastern Standard Time) · Water scarcity (water stress or water crisis) is the lack of fresh water resources to meet the standard water demand.Humanity is facing a water crisis due to unequal distribution (exacerbated by climate change) resulting in some very wet and some very dry geographic locations plus a sharp rise in global fre...
