What is a flowing artesian well?

A flowing artesian well is characterized by the ability of groundwater to rise to the surface under its own pressure without the need for pumping. This phenomenon occurs when the water is confined under an impermeable layer of rock or sediment, creating pressure that forces the water upward when tapped by a well.

In this context, the term "naturally" signifies that the water flows freely without human intervention. The pressure can be strong enough that the water flows out of the well to the surface, resulting in a continuous flow. This scenario is typical in aquifers that are tilted or confined in a way that generates this pressure.

Understanding this concept emphasizes the importance of geological formations and aquifer characteristics in groundwater management. The alternative choices represent different types of wells or methods of groundwater extraction but do not reflect the defining feature of a flowing artesian well.
