Aim: To determine and compare the fluoride concentration in community water supply and packaged drinking water sold in Vadodara city.
Material and Method: A total of 5 water samples were purchased directly from the production sites of packaged drinking water in the Vadodara city. 7 water samples of community water supply were collected from the overhead tank located in the limit of Vadodara Municipal Corporation after getting permission from the City Engineer, Vadodara Municipal Corporation. Fluoride concentrations were determined by standardized Colorimetric method. The Student t test was used to compare the mean fluoride concentration of community water and packaged drinking water at 5% level of significance.
Results: Out of 5 samples of packaged drinking water the level of fluoride is present in only two samples while the remaining 3 samples had no fluoride content. The mean fluoride concentration was 0.05 mg/L. The fluoride concentration of community water supply ranges from 0.1 to 0.26 mg/L with mean fluoride concentration of 0.18 mg/L. The difference observed between the means of two samples was found to be statistically significant.
Conclusion: The result emphasized that the fluoride concentration was low in both community water supply and packaged drinking water sold in Vadodara city. The periodic sample collection of the water must be carried out to control and maintain the fluoride concentration enforced by the sanitary surveillance agency.
