AbstractFluorine contamination in the Rift Valley area, in south Ethiopia is a national problem that requires attention at all country levels. In this context, the Ethiopian Government has shown its determination to support any initiative to help in the potabilisation and sanitation of the waters in this area. Zeolites are a vast natural resource in Ethiopia that remains unexploited due to lack of scientific knowledge and available manpower with a geology background and means to initiate the systematic exploitation of this resource. Natural zeolites have a volcanic origin; they belong to the family of hydrated aluminosilicates and have a microporous structure that can accommodate a wide variety of cations such as sodium, calcium, potassium and magnesium. These cations can easily be exchanged by others in what is one of the main applications of this kind of minerals: ionic exchange.
