Measurement of Fluoride Concentration in Semnan Drinking Water Distribution

The existence of fluoride ion in potable water has distinctive effects on human health. Fluoride is attracted by positively charged calcium in teeth and bones due to its strong electro-negativity which results in dental, skeletal, and non-skeletal forms of xuorosis and associated health complaints in children as well as adults. Water samples from groundwater used for drinking were collected from different water sources (over 22) and fluoride levels were determined through spectrophotometer, DR/5000 (Hach). The mean fluoride concentration was 1.14 ppm. The maximum concentration of fluoride recorded was 1.78 ppm while the lowest was 0.85 ppm. Semnan drinking water is suitable for consumption without any treatment.
