Answer to Question 1

Answer: The well is drilled in an artesian system where water is brought up to the surface under its own internal pressure. For an artesian system to form, the well must be drilled where the elevation of the ground surface is lower than the elevation of the water table in the aquifer at the recharge area.

Answer to Question 2

Answer: Unsaturated zone, saturated zone, water table, recharge area, and discharge area. The unsaturated zone is where pore spaces are partially filled with water, below this area is the saturated zone where all pore spaces are filled with water. The boundary between these two zones is the water table. Water enters an aquifer in a recharge area. Water leaves an aquifer at a discharge areastreams, artesian wells or springs, man-made wells, or as it enters a lake or ocean.
