Question

This is the upper limit of usable ground water.

Answer 1

This is known as the groundwater table or the maximum level to which water can be pumped from underground without causing negative impacts on the aquifer or surrounding ecosystems. Going beyond this limit can lead to depletion of the groundwater resource, saltwater intrusion, land subsidence, and other environmental problems. It is important to manage groundwater usage sustainably to ensure its long-term availability for future generations.
