Abstract– Fluoride contamination of groundwater is a growing problem in many parts of the world. Fluoride is an essential element, which is good for the teeth enamel and helps to prevent dental caries. In excessive doses, however, it will lead to a chronic fluoride poisoning, fluorosis. Therefore it is very important to understand the mechanisms of mobilization of fluoride in groundwater in order to mitigate the problem as effectively as possible. The present study involves laboratory testing of various sources of drinking or potable water in Ranchi City of Jharkhand state. 50 water samples were collected and were tested in laboratory for estimating the concentration of fluoride. Fluoride concentrations in the water samples vary between 0.007 mg/L to 3.800 mg/L with highest concentration in Gonda village of Kanke. Potable water available in public hand pumps recorded the highest fluoride concentration. Most of the fluoride contaminated water sources were found in the north western, south western and southern parts of the Ranchi City.
