Introduction:Nowadays Access to safe and adequate drinking water has been an important national goal in different countries. The lack of control water quality chemicals and physicals is of concern to health authorities in societies. The purpose of this research was to determine the microbial and chemical quality of drinking water in GonbadKavous.
Methods & materials: This descriptive and periodical research was conducted in 1392. A hundred and ninety two samples for testing chemicals and physicals of drinking water were taken. Parameters of chemical and physical, including EC, TDS, Turbidity, Hardness, nitrate, Alkality, Fluoride and remaining chlorine were monitored. Results were reported as mean and standard deviation.
Results:The average residual chlorine, nitrate, Hardness, Fluoride were, 0.17 0.21, 1.55±0.67, 276.5±142, 0.205±0.18 mg/L in a samples of water respectively. An average concentration of EC, TDS was 766±315 µS/cm and 660±123 mg/L respectively. Statistical analysis doesn't show a meaningful difference between the parameters with standard parameters.
Conclusion: The residual chlorine and Fluoride level in all water samples was less than the recommended limits of the standard of Iran. Therefore, the adjusting of fluoride and residual chlorine concentration with standards in the water supply is required by fluoridation and chlorination in water treatment plant or dietary needs.
