Evaluation of Drinking Water Quality in Sardasht, Rabat, and Mirabad Using Schoeller Diagram

Background and Objectives: Nowadays Access to safe and adequate drinking water has been an important national goal in different countries. The effect of ground water contamination is one of the most important concerns of public-health worldwide. The purpose of this research was to determine the microbial and chemical quality of Surface Resources drinking water in Sardasht, Rabat, and Mirabad. Materials and Methods: This descriptive research was conducted in 2015. One hundred ninety two samples were taken for testing chemicals and physicals of drinking water. The analyzes were carried out using machine methods and titration, and the benchmark for comparing the results was based on Iran's national standard and World Health Organization standards, and finally, the quality of resources was compared with the Comparison of Schuler diagrams. Results: The descriptive results show the standardization of most of the parameters, with the exception of the turbidity of its kanirash spring, which is higher than Iran's standard of global health and standardization. The total hardship, resources were also higher than the global health standard, as well as the results of fluoride levels that are lower than global standards and Iran. The results of the statistical analysis indicated that there is a significant difference between the values obtained for the turbidity of the mineral springs (P=0.021) and calcium fountains (P=0.036) with common standards. Conclusions: The residual fluoride level in all water samples was less than the recommended limits of the standard of Iran (1053). Therefore, the adjusting of fluoride concentration with standards in the water supply is required by fluoridation in water treatment plant or dietary needs.
