Water confined under pressure in a permeable deposit beneath impermeable rocks; if under sufficient pressure, a bore put down in the area will result in a flowing spring or artesian bore.
Subsurface water underlying a confining bed which has sufficient pressure to rise above existing ground (or water surface) when encountered in cased holes during drilling.
water that is under pressure, naturally. When tapped by a well (or spring) it isable to flow upward. If it flows to the surface it is flowing artesian.
Ground water under sufficient pressure to rise above the level at which the water-bearing bed is reached in a well. The pressure in such an aquifer commonly is called artesian pressure, and the formation contains artesian water is an artesian aquifer.
Groundwater within a confined unit or layer that is under sufficient hydrostatic pressures such that it rises above its level of confinement when breached by a well or natural spring
ground water that is under pressure when tapped by a well and is able to rise above the level at which it is first encountered. It may or may not flow out at ground level. The pressure in such an aquifer commonly is called artesian pressure, and the formation containing artesian water is an artesian aquifer or confined aquifer. See flowing well
