Underground aquifers are the water source for 70% of the world’s irrigation use. Many of these aquifers have experienced steep drops in water pressure and are endangered from over consumption. For example, the figure below shows groundwater spewing from an artesian well that was drilled in 1888 in Woonsocket, South Dakota, USA. Initial wellhead pressure was 250 psi (1.7 MPa), dropping to 35 psi (0.25 MPa) by 1923 (Meinzer and Hard, 1925).
