saturated zone

The saturated zone is a layer of soil or rock below the ground where all the spaces between the particles are completely filled with water. This area is beneath the unsaturated zone, where some air can still occupy the spaces. The water in the saturated zone is typically accessed through wells, and it plays a crucial role in supplying groundwater for agricultural, industrial, and drinking purposes. This zone can vary in depth depending on the location and local environment, influencing the availability of groundwater resources.
