This year's celebration of World Water Day features groundwater. Out of sight, under our feet, groundwater is a hidden treasure that enriches our lives. In the driest parts of the world, it may be the only water people have.

Groundwater is being over-used in many areas, where more water is abstracted from aquifers than is recharged by rain and snow. Groundwater pollution is a particular problem that can take decades or even centuries to recover from. In some places, we do not know how much groundwater lies beneath our feet, which means we could be failing to harness a potentially vital water resource. 

Exploring, protecting and sustainably using groundwater will be central to surviving and adapting to climate change and meeting the needs of a growing population. That is why UN Water is putting emphasis on 'Groundwater may be out of sight, but it must not be out of mind.'

What is World Water Day

World Water Day is on 22 March every year. It is an annual United Nations Observance, started in 1993, that celebrates water and raises awareness of the 2 billion people currently living without access to safe water. A core focus of World Water Day is to inspire action towards Sustainable Development Goal (SDG) 6: water and sanitation for all by 2030.
