Abstract: Physical, chemical and microbial properties of drinking water are the base of judging its drinkability. Undesirable changes in these parameters can threaten consumers’ health. Therefore, the purpose of this study is to investigate the physical, chemical and microbial quality of drinking water and compare it to national standards. This cross-sectional descriptive study was conducted in 2011-2014. Moment sampling was done from the water of distribution network of 15 locations in the city. Totally, 1780 samples were collected for microbial analysis and 30 samples were collected for chemical analysis. Standard methods according to the book “Standard Method” were used to carry out the experiments. Research results showed that the remaining chlorine in 2012 was zero in 22 samples and <0.2 Mg L-1 in 3 samples. Fecal coliform was negative in all cases. In addition, the physical and chemical parameters under study were standard. In 2013, the remaining chlorine was zero in 16 cases and more than 0.8 Mg L-1 in 23 cases. Thermo-tolerant coliform was also observed in 1 case. All the parameters were standard and desirable. In 2014, the remaining chlorine in the distribution network was zero in 19 cases and it was between 0.1-0.4 in one case and >0.8 in 8 cases. Also, in 2014, no coliforms were observed in the cases. It was clarified in physicochemical experiments that the amount of fluoride is less that the standard level. The health quality of drinking water in Kamyaran City is not problematic and it is not standard in many cases in terms of the remaining chlorine and fluoride.
