A DETAL STUDY ON DRINKING WATER QUALITY AND DENTAL FLUOROSIS IN MELUR

In this study groundwater quality with reference to fluoride and other chemical parameters such as pH, total alkalinity, hardness, calcium and salinity was tested in Samples collected from Melur, a dental fluorosis prone area. Nineteen water samples from various sources viz., well, bore well and hand pump collected in different sites of the study area were examined. The study reveals that all the parameters except salinity are within standard limits in municipal water. Six ground water samples were found to have high fluoride levels above the Indian standard for potable water (1.0 mg/l). The study shows that elevated fluoride level is associated with lowering of hardness and calcium levels in water. The present investigation suggests that people of Melur should be advised to consume only municipal water. Ground water can be used for potable purpose only after its treatment for fluoride. Awareness on the consequences of excessive fluoride intake and its preventive Strategies must be given.
