Which type of well rises to the surface due to natural pressure in a confined aquifer?

Which type of well rises to the surface due to natural pressure in a confined aquifer?

• A. Artesian well
• B. Dug well
• C. Drilled well
• D. Driven well

Answer: (A)

Natural pressure in a confined aquifer can push groundwater up into a well. When a well taps into this pressurized zone, the water rises in the borehole and may reach the surface without pumping. This is called an artesian well. Dug wells are shallow and rely on the water table rather than underground pressure; driven and drilled describe how the hole is made, not the pressure that lifts the water. So the artesian well is the type that rises to the surface due to natural pressure in a confined aquifer.
