Detailed explanation-1: -An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.

Detailed explanation-2: -An aquifer also may be called a water-bearing stratum, lens, or zone. Wells can be drilled into many aquifers, and they are one of the most important sources of fresh water on Earth.

Detailed explanation-3: -The upper surface of this water-filled area, or “zone of saturation", is called the water table. The saturated area beneath the water table is called an aquifer, and aquifers are huge storehouses of water.

Detailed explanation-4: -What is an aquifer? Although groundwater exists everywhere under the ground, some parts of the saturated zone contain more water than others. An aquifer is an underground formation of permeable rock or loose material which can produce useful quantities of water when tapped by a well.

Detailed explanation-5: -Figure 2 is a simple cartoon showing three different types of aquifers: confined, unconfined, and perched. Recharge zones are typically at higher altitudes but can occur wherever water enters an aquifer, such as from rain, snowmelt, river and reservoir leakage, or from irrigation.
