Abstract
The present study deals with ground water quality with respect to the fluoride content in water resources of Kalahandi and Nuapada districts of Odisha, India. Water samples were collected in different locations covering tap water, open wells, tube wells and river waters. Ground waters of tube wells are highly polluted with fluoride in comparison to open wells. In Nuapada district out of 4920 tube wells 399 contains 1.5-3.0 (mg/L) and 114 are from 3-5(mg/L) and 22 are from 5-6.5> (mg/L). A survey report shows 22557 people are affected with fluorosis and nearly 2 lakh people are in risk. In Kalahandi district Karalkot, Kerijhola and Binapur water supply contains objectionable fluoride content i.e. 3.88 mg/L. Dental fluorosis was observed among school children in Boden and Sonapalli blocks. In view of the severity of the problem the defluoridation techniques need to be evolved to reduce or minimize the fluoride concentration in drinking water.
