Q. What is artesian water?

A: Artesian water is simply 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. Artesian has nothing to do with quality or taste of water.
