Background and Objective: Microbial and physicochemical properties of drinking water، considering type and quantity of drinking water, are factors for determining the acceptability of water. The effects of each of the above components on increasing the quality of water or threatening the health of consumers are also considerable. We aimed to investigate the trace amounts of microbial, physicochemical parameters of drinking water in Takab, comparing to national and international standard.

Materials and Methods: This cross-sectional study was performed in order to monitor water quality that 17290 samples were taken for determination of chlorine residual of water, 1055 samples for microbial analysis and 87 samples for chemical analysis and the results were compared with the standards. Finally, all of data were analysed by Mann-Whitney U statistically.

Results: 66.7% of chlorine residual of water had standard rate and 33.3% of the cases were higher or lower than the standard. 12.3% of rural water was contaminated by E.coli. Average total hardness was 247.4±110.2, at 100% of samples Sulfate ion was maximum allowance and 98.9% optimal,  Magnesium ion at 100% of samples were maximum allowance and 85.1% Optimal, Fluoride ion at 10.3% of sample Allowance and 89.7% less than allowance. Other ions are also at the maximum allowance and optimal.

Conclusion: The quality of drinking water in the surveyed villages was around the area according to Iran's National Standard for water. The chemical quality of water in some villages had higher hardness than optimal levels, fluoride in most villages was less than standard limit.

Key words: Microbial quality, Physicochemical quality, Drinking water.

 

Funding: This research was personally funded.

Conflict of interest: None declared.

Ethical approval: The Ethics Committee of west Azerbaijan University of Medical Sciences approved the study.
