Which well(s) will NOT provide water? Explain why not.
Wells 2 and 4; Well 2 is dry because it does not reach below the water table, and Well 4 is dry because it ends in an unsaturated (impermeable) zone.
Well 1. It can't reach the water table.
Wells 3 and 5 because they can't get through the impermeable layer.
Describe how water enters Aquifer A.
When it rains, water soaks into the ground. It then becomes groundwater.
People pump water underground to save for later, so they can then pump it back up for later use.
Deep blue holes leak water underground and allow for clean drinking water.
