In this descriptive and analytical study, the number of 551 samples during 4 seasons of 2013 year from rural drinking water sources via rural water and Wastewater Company has been taken. The concentration of fluoride in water samples was measured using SPADNS method. Results shows that the average concentration of fluoride in drinking water supplies for the rural region of Khash, Sarbaz, Iranshahr, Saravan, Nickshahr city are 0.72 (±0.31), 0.55(±0.21), 0.33 (±0.127), 0.6 (±0.24), 0.435 (±0.23) respectively.
