The requirement of iodine is met from food and water when the soil content of iodine is adequate. It is a common belief that population living near the sea coast is spared from iodine deficiency disorders. A cross sectional descriptive study was conducted among the school going children between classes 5 to 8 to evaluate the iodine content of drinking water being consumed by the population in the district of Puducherry. A total of 86 samples were analysed by catalytic reduction method of which 12 samples were from hand pumps and 74 samples from the municipality. The mean iodine level in the water sample was found to be 9.27 ± 3.4 μg per dl. Some communes however had lower iodine levels in drinking water. The water iodine levels contribute significantly to the daily intake of iodine.
