aquifer systems

An aquifer is a underground layer of water-bearing porous rock or sediment that holds and transmits groundwater. These systems store freshwater that can be accessed through wells for drinking, agriculture, and industry. Aquifers are replenished naturally by rainfall infiltrating the ground. They vary in size and capacity and are crucial sources of freshwater for many regions. Understanding aquifer systems helps manage water resources sustainably, prevent over-extraction, and protect against contamination. Essentially, aquifers function like underground reservoirs, providing a vital, naturally stored supply of clean water.
