Nakuru, Baringo, Kenya: The problem of excess fluoride in water has been overlooked in Nakuru and Baringo counties for a long time, although the Government and local organisations have improved access to water in both rural and urban areas. 

Major water sources in the Rift Valley have a high fluoride content, above the World health Organisation’s (WHO) guidelines that recommends less than 1.5 milligrammes per litre of drinking water.
