How much more groundwater is typically available compared to surface water?

Groundwater is generally much more abundant than surface water due to its widespread presence beneath the Earth's surface. It is stored in aquifers—geological formations that can hold and transmit water. Groundwater represents a significant portion of the world's freshwater supply, often calculated to be approximately 20-30 times more available than surface water sources like rivers, lakes, and reservoirs.

Surface water is more susceptible to evaporation and contamination, which can restrict its availability in certain areas, particularly in arid climates. In contrast, groundwater is often more reliable and can be accessed even during dry periods, making it a crucial resource for human consumption, irrigation, and industrial uses.

This context highlights the importance of groundwater as a critical and more stable water resource compared to surface water.
