You have a choice to drill your water well into a shallow, unconfined aquifer or a deeper artesian aquifer. Drilling deeper will cost more money; however, you chose to drill into the artesian aquifer. Why?

    The confined aquifer will contain more water.

    The confined aquifer will contain more water.

    Explanation:

    A shallow aquifer will not have plenty of water, so although you spend less money drilling that aquifer, you will not have water for a long time and will soon have to spend more money to drill another aquifer. On the other hand, a coined aquifer, although it needs more money to be drilled contains more water, being a better option.

    Confined aquifers occur when groundwater is confined under a higher pressure than atmospheric pressure, due to the existence of an impermeable confining layer above the aquifer. Because water is at a higher pressure than atmospheric pressure when drilling a hole, water rises to the piezometric surface, giving rise to an artesian hole. Thus water reaches the surface in the form of a draw, and the artesian hole is called a repurring hole.
