Percolates refers to which process in groundwater?

Percolation is the downward movement of water through soil and rock after it infiltrates from the surface, continuing until it reaches the saturated zone and becomes groundwater. This recharge process differentiates groundwater from surface pathways. Water that runs off the surface becomes surface water, water that evaporates returns to the atmosphere, and none of those describe the downward movement into the ground to form groundwater.
