World Water Day is an annual United Nations Observance, started in 1993, focusing on the importance of water, coordinated by UN-Water and led by one or more UN-Water Members and Partners with a related mandate. This year the theme is "Groundwater - Making the invisible Visible'. Groundwater is invisible, but its impact is visible everywhere and is a hidden treasure that enriches our lives. Globally, Groundwater accounts for 30% of the world's freshwater resources and has high microbiological quality and virtually requires no treatment in many cases.
Good groundwater management is needed to achieve most of the Sustainable Development Goals (SDGs) of Agenda 2030. Furthermore, It is estimated that groundwater contributes about 62 % of the total water requirement of Ghana serving mainly the unreached populations. Additionally, 41% of water users permitted by the WRC in 2020 use groundwater as the only source. The quality of groundwater resources in Ghana is generally good except for some cases of localized pollution and areas with high levels of iron, fluoride and other minerals. Salinity in certain groundwater occurrences is also found especially in some coastal aquifers. What is critical to Sustainable management of underground water is finding the right balance between withdrawing and letting the aquifer's level recover to avoid overexploitation and pollution. The National Planning Committee for WWD 2022 will undertake a series of event to mark the day and raise awareness on the theme to various target groups including WASH sector actors, policy formulators, policy makers, the media, advocacy groups, water institutions, water managers and practitioners.
