what would a person drilling a well most likely reach immediately after drilling through the unsaturated zone?\no a spring\no an aquifer\no the water table\no an impermeable layer
Answer
Brief Explanations:
The water - table is the upper surface of the saturated zone. After drilling through the unsaturated zone, the next layer is the water - table. A spring is a place where water flows out of the ground, an aquifer is a saturated rock layer that can yield water, and an impermeable layer restricts water flow and is not the immediate layer after the unsaturated zone.
Answer:
the water table
