Groundwater is present almost everywhere beneath the land surface. It is essentially a subsurface reservoir of water that represents 98% of the Earth’s unfrozen freshwater. Groundwater is recharged by surface water from rain, rivers, snow, or melting ice.
Founded in January 2022, GroundwaterU bridges the knowledge gap between groundwater experts and the millions of people who need to make decisions and take actions to sustain access to clean water for drinking and agriculture water everywhere.
Billions of people rely on groundwater. It is used for almost 50% of drinking water and is a primary source for irrigation water, and it sustains water in rivers and lakes during periods of drought. Groundwater is an essential resource that sustains humans, animals, and ecosystems.
