Abstract: This article reports the presence of fluoride in the brine samples obtained from the salt pan. Previous researches have proved that water is the main source for fluoride and suggested various defluoridation techniques. The availability of fluoride beyond a limit causes a severe disease called fluorosis. On the otherhand if the level is less than the required amount then it leads to dental caries. As per the recommendations of WHO, the permissible limit is 1.5 mg/l. Here we have analyzed brine, salt and pan soil samples collected from Vandikaratheru salt pan, Ramanathapuram District. Investigation revealed that the maximum fluoride level in the brine samples was 1.6 mg/l and the minimum level in the brine samples was 1.0 mg/l. The fluoride level in salt was also studied and it was recorded to be 1.0 mg/l. During the formation of salt, there was a reduction in the amount of fluoride. Maximum fluoride got settled into the pan soil which was found to be 1.2 mg/l.
