artesian aquifer

An artesian aquifer is a type of groundwater storage where water is trapped beneath layers of impermeable rock or clay. When a well is drilled into this aquifer, the pressure can cause the water to rise to the surface without needing a pump. This phenomenon occurs because the water is under pressure from surrounding layers. Artesian aquifers are significant sources of fresh water in many areas and are crucial for drinking water supplies, agriculture, and industry. Their sustainable management is essential to prevent depletion and contamination.
