Assessing groundwater salinity across Africa

“…Because of the high solubility of evaporites, even groundwaters with short residence time may acquire high salinities. Rock dissolution explains the high groundwater salinity (Figure 2) encountered in large sedimentary aquifer basins such as the Juba Shebelle basin in Somalia, the North Western Saharan Aquifer basin in Tunisia and Algeria (Pina et al, 2017;Yangui et al, 2012), and Karoo sediments in South Africa. However, other factors play a role in exacerbating rock dissolution induced salinization.…”
