Background and Objectives: Fluoride is an essential element for human health body, since in standard levels, it prevents the tooth decay and then in maximium levels it leads to florsis. On the other hands, nitrate is another constitutes which is introduced to ground water resource due to release of industrial and municipal wastewater. The presence of nitrate in ground water well demonstrates the introduction of wastewater and lead to blue baby. Material and Methods: In this work, concentration of nitrate and fluoride during 6 months was investigated in Karaj water supply system. The samples were taken monthly from 12 area of Karaj City. For each area, about 8 samples were taken. After sampling, concentration of nitrate and fluoride was measured and compared with available standards. Results: The results reveal that maximum and minimum of nitrate was 32.53 and 4.11 mg/L, respectively. In addition, minimum level of fluoride was zero and maximum was measured to be as 0.72 mg/L. Based on results, nitrate concentration was bellow the available standards and therefore has no health risk to consumer. However, the fluoride concentration was below the permitted level for human being and therefore needs to establish fluoridation facility. Conclusion: We can conclude that Karaj water supply system is suitable considering nitrate concentration but it need to establish a fluoridation facility to prevent dental disease.
