A water table describes the boundary between water- saturated ground and un saturated ground. Below the water table, rocks and soil are full of water. Pockets of water existing below the water table are called aquifers. An area's water table can fluctuate as water seeps downward from the surface. It filters through soil, sediment, and rocks.
