Abstract

Fluorosis has become a major problem in India. The present study is concerned with the potability of ground water samples in the Musiri Taluk ofTiruchirappalli District. Water quality parametric studies such as pH,Total alkalinity,Total Dissolved Solids,Total Hardness, Phosphate and Fluoride were performed for 65 water samples from the Hand pump, Bore well and open well sources.The water samples were categorized with respect to the level of fluoride content in the water samples.The calculated water quality indices (WQI) reveal the non-potability of 49% of the water samples. The dental fluorosis survey revealed that I 7.6% of the children (age 7-13 years) were found to have affected by the disease. Defluoridation study using coal as an adsorbent, showed adsorption efficiency of 84% at a pH value of 8.0 using the sieve size of 75 mm for a 2.0 mg/L fluoride solution.
