WATER FLUORIDE IN THE MOLO DIVISION OF NAKURU DISTRICT, KENYA

Water samples were collected from 40 households in four sublocations o f the Mole division of the Rift Valley in Nakuru District of Kenya. Th e mean fluoride concentration was 0.28 +/- 0.03 ppm. Of the samples co llected, 62.5% were from streams/springs, 15.0% from;tap water, 10.0% from borehole; water,10.0% from dam water, and 2.5% from rain water. T uri sublocation had 75% of the total number of boreholes in this study , and had the highest mean fluoride concentration (0.44 +/- 0.06 ppm), whereas Kamara had the lowest mean fluoride concentration (0.19 +/- 0 .08 ppm). Kerisoi and Sachagwan sublocation had mean fluoride concentr ations of 0.21 +/- 0.07 ppm and 0.32 +/- 0.04 ppm, respectively. Boreh ole water had more fluoride (0.66 ppm) than any other water source, wh ile rain water had the least amount of fluoride (0.07 ppm). The highes t fluoride encountered in this study was 2.0 ppm while the lowest was 0.06 ppm.
