Abstract– Water crisis is a major problem in the present scenario. Due to excessive use of chemical fertilizers, pesticides, dumping of wastes from industries, release of industrial effluents on open land, dumping of domestic wastes, the groundwater has got polluted in many areas throughout the world. Fluoride rich minerals present in the earth crust results into groundwater fluoride contamination naturally. The intake of fluoride rich water results into a medical condition called fluorosis- a severe bone disease. Hardia Sector D (Jajpur), Singar Khas, Hanuman Nagar and Bhaunr villages of Rajauli block of Nawada district, Bihar are among the fluorosis endemic areas. Most of the groundwater sources in these villages have fluoride concentration above the maximum permissible limit of 1.5 mg/L. People suffering from skeletal fluorosis, non-skeletal fluorosis and dental fluorosis were found in the villages.
