Drinking water supply for the Main Ethiopian Rift (MER) area principally relies on groundwater wells and springs and is characterized by fluoride contamination. New analyses reveal that the F~- geochemical anomaly is associated with other potentially toxic elements such as As,B,Mo,U,Al,Fe and Mn. Particularly,35%of the 23 investigated groundwater wells and 70%of the 14 hot springs(and geothermal
