Abstract
Excessive and undesirable level of fluoride in drinking water supplies is a major problem in the Rift Valley of Ethiopia. It has been reported that people in the Rift Valley of Ethiopia are consuming water up to 33 mg L-1 of fluoride. The WHO has set 1.5 mg L-1 as the maximum permissible limit for fluoride in potable water. Sustained intake of fluoride beyond this limit can cause dental or skeletal fluorosis, which is a chronic disease manifested by mottling of teeth in mild cases, softening of bones and neurological damage in severe cases, therefore adequate measures for the reduction of the level are important. It is also expected that the fluoride concentration may increase mainly because of the excessive utilization of ground water as these area are characterized by water scarcity. In areas where alternative water sources are not available, physical or chemical treatment of water is the best option to control fluorosis. The methods of fluoride removal used by industrialized countries require more technical support for operation and maintenance than is possible in the rural areas of developing countries.
