under pressure when tapped by a well and able to
rise above level at which first encountered. It may or may not flow out at ground level.

- a. Ground water that is under sufficient pressure to rise above the level
at which it is encountered by a well, but that does not necessarily rise
to or above the surface of the ground. AGI
b. Ground water that is confined within a permeable bed and that rises
under pressure to approx. the height of the intake. If the outlet (well or
spring) is appreciably below the height of the intake, the water will flow
out under pressure. If even with or above the height of the intake, the
water will rise in the well but it will not flow out. Bateman, 2
