![]() At the beach, the level of the water table is always at the same level as the ocean, which is just below the surface of the beach.Īs you may have read, most of the void spaces in the rocks below the water table are filled with water. In our sand hole example, you have essentially dug a "well" that exposes the water table, with an aquifer beneath it. The saturated area beneath the water table is called an aquifer, and aquifers are huge storehouses of water. The upper surface of this water-filled area, or "zone of saturation", is called the water table. ![]() Have you ever dug a hole at the beach and watched as it partially filled with water from the underlying sand? This is a great way to illustrate the concept of how the ground, if it is permeable enough, can hold water but still stay solid. Groundwater is one of our most valuable resources-even though you probably never see it or even realize it is there. The upper surface of this zone of saturation is called the water table. A hole dug at the beach illustrates the concept of how the ground, if it is permeable enough, can hold water.
