Question

Quizplus · Accepted Answer

The main source of groundwater is precipitation that percolates downward as gravitational water. This water eventually reaches the water table and becomes groundwater. While hygroscopic water in the soil and the zone of aeration above the water table can contribute to groundwater recharge, they are not the main sources. Surface water can also contribute to groundwater recharge, but it is not the main source as it only intersects the zone of recharge.
