Determination of Fluoride Concentration in Tehran Surface Water Resources

摘要

Tehran potable water is mainly provided from surface water resources including the Karaj and Jajrood RIVERS. There are no documented and valid data on fluoride concentrations in different Tehran water supplies. This study determined fluoride concentrations in surface water resources supplying Tehran drinking water. In this regard, eight stations along the Karaj River and five stations along the Jajrood River have been selected and during eight months study representative samples were taken as two-month intervals. Fluoride concentrations were 0.19-0.33 and 0.34-0.43 mg/L in the Karaj and Jajrood RIVERS respectively. These concentrations are below WHO drinking water standard limits (0.7-2.0 mg/L) and thus it is recommended to adjust the fluoride concentration in the water treatment plant or provide it through other ways such as supplementary diet programs.
