Study of fluoride in ground water around the BALCO, Korba area (India).

The present study was undertaken for the determination of fluoride ions in drinking water at the BALCO, Korba region by the ion selective electrode method. The ground water samples of thirty four villages of this region were collected. The fluoride concentration values varied from 1.07 ppm to 3.10 ppm. In this area, villagers were found suffering with dental and skeletal fluorosis. The villagers were suggested to use alum, lime and Nalgonda technique to avoid all type of fluorosis. It was found that fluoride was present within the permissible limit (1.5 ppm) in most of the villages studied but the fluoride level was unacceptable in drinking water samples taken from some villages of BALCO, Korba area.
