Abstract : The presence of excessive amount of fluoride in bore wells and drinking water causes dental fluorosis, mottling of teeth etc. Ground water contains fluoride ions dissolved from geological formations. The presence of low concentration or absence of fluoride in water results in a high incidence of dental caries in children's teeth. Therefore the concentration of fluoride should be within permissible limit as prescribed by various organization such as ICMR, WHO, ISI, etc. Hence, it becomes very important to analyse the fluoride in bore wells water used for drinking purpose. In the present study, fluoride content has assessed by std. experimental procedure and found in the range 0.005 to 0.670 ppm at different sampling stations of Chikhli City during Jan 2006 to June 2006.
