With our current focus on The Power of Hydration, we are highlighting World Water Day, held on March 22nd every year since 1993. In 2022 the focus is: Groundwater - Making the invisible visible. Out of sight, under our feet, groundwater is a hidden treasure that enriches our lives. Almost all of the liquid freshwater in the world is groundwater. As climate change gets worse, groundwater will become more and more critical. We need to work together to sustainably manage this precious resource. Groundwater may be out of sight, but it must not be out of mind.
