. What is an aquifer’s recharge zone?

Permeable areas of the ground where surface water and rain can enter the aquifer to refill it

Why are wells dug much deeper than the top of the water table?

So that if the water level drops, the well won’t run dry

The Ogallala Aquifer’s water mostly came from melting glaciers 10,000 years ago. How is it recharged today?

From rain and surface water

Is enough water being deposited in the aquifer today to keep it from going dry?

Nope, we are pumping out more of the 10,000 yr old water than is going back in, because that area is pretty dry

The END
