Author(s): Jayanta Chutia and H. P. Sarma

The present investigation has been undertaken to determine the fluoride and nitrate contents in drinking water samples of the study area. Twenty water samples were analysed during May-June 2008 for pH, total hardness, fluoride and nitrate contents by adopting standard methods (APHA-AWWA-WPCF, 1995). The data obtained were within the standard permissible limits of WHO. Average nitrate contents was higher than average fluoride contents in case of most of the tube wells. In ring wells, the fluoride content exceeded the nitrate content.
