Anomalously high concentration of fluoride (up to 16 ppm) has been observed in dug/tube well water, which is being used for drinking and irrigation purposes, around Palri, Andor and Wan villages, in western part of Sirohi district, Rajasthan. Fluoride concentration in groundwater is much higher than the permissible limit of 0.6-1.5 ppm of fluoride recommended for potable purposes. Water samples with more than 5 ppm fluoride are confined to Andor and Wan villages. Mottling is commonly observed in people of this area with a few cases of crippling fluorosis. Areas with such a high fluoride content require serious attention and remedial measures like setting up of large-scale defluoridation plant, use of simple domestic defluoridation methods and public awareness for preventing harmful diseases like fluorosis.

Key words: Fluorosis; Groundwater fluoride; Rajasthan, India.
