Abstract

Background: 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. Methods: 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). Results: 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. Conclusion: Semnan drinking water is suitable for consumption without any treatment.
