World Water Day 2022

World Water Day, held on 22 March every year since 1993, focuses on the importance of freshwater. The theme for 2022 is Groundwater, Making the Invisible Visible.Groundwater is the largest source of freshwater on earth, accounting for almost 99% of all liquid freshwater on earth. In many areas, groundwater is the only source of freshwater for domestic, agricultural and industrial water needs. However, groundwater levels are depleting due to excessive extraction of water than is recharged by rain and snow. Existing groundwater is also being polluted due to seeping in of pollutants from the surface, sewers and polluted rivers. Groundwater pollution is a virtually irreversible process.

Due attention should be given to protecting groundwater against pollution and overexploitation, for a sustainable use of this fragile and precious resource.
