text: When a well is drilled into a confined aquifer, the water that is under pressure in it will rise in the well casing and may reach the surface.
text: To be an artesian well, the water in the aquifer (a subsurface rock unit that holds and transmits water) must be under enough pressure to force it up the well to a level that is higher than the top of the aquifer.
text: Some deeper water bearing units like the Dakota aquifer contain consolidated (e.g., sandstone) layers, and may be separated from the surface by confining layers impermeable enough so that the deep water can be under pressure.
text: Water is under pressure due to confined layer.
text: Water is under pressure.
