What are the types of aquifers?

Aquifers are underground layers of permeable rock or sediment that hold water. There are several types of aquifers based on their geologic formations. Unconfined aquifers, also known as water-table aquifers, are closer to the surface and have a water table that fluctuates based on precipitation and groundwater extraction. Confined aquifers, on the other hand, are surrounded by impermeable rock or clay layers, and they are under high pressure, creating artesian wells when drilled. Fractured aquifers occur in areas where rocks have cracks or fractures, allowing water to flow through them. Lastly, karst aquifers develop in regions with soluble rocks like limestone, where water flows through interconnected underground channels and caves. Each type of aquifer has different characteristics and must be managed carefully to maintain a sustainable water supply.
