What is the primary reason for the decline in water tables in some groundwater dependent areas?

The primary reason for the decline in water tables in some groundwater-dependent areas is over-pumping. This occurs when water is extracted from groundwater sources at a rate that exceeds the natural recharge of the aquifer. Groundwater is replenished through precipitation and surface water infiltration, but when water is withdrawn more quickly than it can be replaced, it leads to a significant drop in the water table. Over-pumping can lead to various issues, including reduced water availability for agriculture, drinking water, and ecosystems, as well as increased groundwater salinity and land subsidence. Understanding the impact of over-pumping is crucial for sustainable water resource management.
