All countries have a variety of water resources – some are on the surface, like rivers, and some are beneath the ground. This groundwater provides almost 50% of all global domestic use and 43% of all the water used for agriculture.
Groundwater is stored in aquifers, which come in a variety of shapes and sizes. They can be accessed in several ways, but mostly by drilling wells. Not all groundwater is useful to us – it depends on whether it’s fresh or mixed with salt and on how deep it is, as this will affect how easy it is to tap into.
