<P> A spring is any natural situation where water flows from an aquifer to the Earth's surface . It is a component of the hydrosphere . </P> <P> A spring may be the result of karst topography where surface water has infiltrated the Earth's surface (recharge area), becoming part of the area groundwater . The groundwater then travels through a network of cracks and fissure--openings ranging from intergranular spaces to large caves . The water eventually emerges from below the surface, in the form of a karst spring . </P> <P> The forcing of the spring to the surface can be the result of a confined aquifer in which the recharge area of the spring water table rests at a higher elevation than that of the outlet . Spring water forced to the surface by elevated sources are artesian wells . This is possible even if the outlet is in the form of a 300 - foot - deep (91 m) cave . In this case the cave is used like a hose by the higher elevated recharge area of groundwater to exit through the lower elevation opening . </P>

Where does water from a spring come from
