Background: Water is an important transmitter of pathogenic agents. So drinking water must be refined and disinfected. Due to the importance of the subject and in order to evaluate the quality of drinking water this study was performed in Zanjan during the year 2000.
Materials and Methods: In this descriptive study, microbial indicators and chlorination quality of water were determined to ensure the quality according to WHO recommendations. Sample numbers were estimated based on one sample per 10000 population plus 10 additional samples. Samples were examined for coliforms by the 5 tube fermentation method. Residual chlorine was estimated using Di-ethyl-P-phenylene d-amine by colorimetric method.
Results: Microbial examination in presumptive and confirmatory stages revealed a desirable quality in %95 and 98% of samples respectively. Also, the amount of residual chlorine among all of the colorimetric subjects was as the following: 0.5-0.8 mg/lit (Standard amounts) in 75-78% of samples, Zero in 1.85%, and <0.5 mg/l or >0.8 mg/l in 12.4% of samples. Turbidity and PH were also measured and appeared to be in the standard ranges.
Conclusion: Based on WHO water quality guidelines and national microbial standards the quality of drinking water of Zanjan city has desirable standard values.
