The aquifer layer that contains water that can be extracted easily is known as an unconfined aquifer. Unconfined aquifers are replenished directly by rainfall and surface water. They are typically located near the ground surface and do not have a significant layer of impermeable material above them, which allows for easy extraction through wells or natural springs. Managing unconfined aquifers is essential for sustainable water supply and is crucial in regions dependent on groundwater for agriculture, drinking water, and industry.
