World Water Day 2022 – Groundwater: The Liver of our Rivers

The theme of this year’s World Water Day is “making the invisible visible” with a special emphasis on the importance of groundwater. Groundwater is quantitatively the most important freshwater resource as there is 100 times more groundwater than surface water1. In fact, it is where we source most of our fresh drinking water. Of similar importance, without groundwater, rivers would run dry and face a deterioration of water quality and ecosystem health.
