Abstract : Water contamination is a major problem in the present scenario. The groundwater of many sources have become polluted. The contamination is due to both natural reasons as well as due to human activities. The groundwater of some villages of Rajauli block of Nawada district, Bihar is highly contaminated with fluoride – the intake of which has resulted into a severe bone deformity called fluorosis. The maximum permissible limit of fluoride in groundwater as per the WHO guidelines is 1.5 mg/L. However many groundwater sources of Hardia Sector D (Jajpur) have fluoride level more than the permissible limit and in one of the sources it has reached the value of 3.59 mg/L. Many visible cases of fluorosis have been found in the village.
