Jun 18, 2018 · Groundwater Storage and the Water Cycle. The ground stores huge amounts of water and it exists to some degree no matter where on Earth you are. Lucky for people, in many places the water exists in quantities and at depths that wells can be drilled into the water-bearing aquifers and withdrawn to server the many needs people have. The ground ... 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.
