An artesian well is a well that is dug into the ground to the water table and is under pressure and will spray out of the well head like a oil geyser.
Take two dousing rods (bent metal coat hangers into straight ¬ shapes work) Hold them level in front of you, until they cross. They cross above a water supply, so that would be a good place to dig.
well water is pump of of the ground, artesian well water comes out of the ground by itself
There is no such thang as an 'artisan spring'. Artists create many things; springs are not among them.
a borehole into the lower stratum below the water level so that pressure forces the water upwards
