Hi. Here in Newfoundland, Canada and Artesian well is drilled down at
usually around 200', a casing is put in the drilled hole and water is
pushed up through the ground using a pump in most cases.
If it is pumped, it is not an artesian well... An artesian well can be
drilled or natural, but the key ingredient is that it must be under
enough natural pressure for the water to come to the surface on its
own...
Poor definition.
According to the US Geological Survey, any subsurface water that is
under pressure underground is artesian, even if the pressure is not
strong enough to cause the water to flow to the surface.
The artesian surface needs only to be moderately above the confining
rock layer in order to be classified as artesian. Wells in Brunswick
Georgia in the 1880s were so strongly artesian that they could supply
multistory buildings without pumping, however today, almost all of these
wells require pumping to get the water to the surface as there has been
so much depletion of the aquifer.
