Ground water contains fluoride ions dissolved from geological formations. Fluoride at optimal level decreases the incidence of dental caries and is also necessary for maintaining the integrity of oral tissues but at the same time when taken in excess during development stages can cause adverse effects like dental fluorosis, skeletal fluorosis , mottling of teeth, osteoporosis etc. Therefore, the concentration of fluoride should be within permissible limit as prescribed by various organizations such as WHO, ICMR and BIS. Hence, it becomes very important to study the fluoride concentration in the ground water used for drinking purpose. In the present study, fluoride content has assessed by standard analytical procedures and found in the range 0.211 to 0.619ppm at different sampling stations of Atrauliya Nagar Panchayat during Jan 2014 to Nov 2014.
