  Background and Objectives: Access to safe and adequate drinking water has been an important national goal in different countries. On the other hand, the possibility of microbial contamination and lack of control water quality chemicals 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 bardsir in 2009-2010 and comparing the results of the study with valid standards of Iran and guidelines of WHO.

  Material and Methods: This descriptive and periodical research was conducted during Augast 2009 to end of March 2011. Two thousand and seven hundred and twenty six samples for testing microbial and134 samples for chemical testing of drinking water was taken. Parameters of corrosion, including Langelier index, Ryzener , aggressive, concentration of nitrate and nitrite quantity of fecal coliforms and remaining chlorine were monitored. All the methods used for sampling and testing of the Book of Standard Test Methods Water were adapted. The results were analyzed with SPSS software. Results were reported as mean and standard deviation.

  Results: The average residual chlorine water and focal coliform was found in samples of water (0.31± 0.23) mg/L and (1.81±1.6) mg/L was respectively determined. Average concentrations of nitrate and nitrite in water sources of bardsir, (7.48 ± 4.54) mg/L and (0.023 ± 0.026) mg/L average corrosion index including langelier saturation index, Ryzener index and Aggressive index +0.41, 7.01 and 12.36 of drinking water respectively was achieved.

  Conclusion : The averages of index the lack of desirability coliform bacteria %95.2 according to WHO guidelines range was good. Nitrite and nitrate levels in all water samples of bardsir was less than the recommended limits of the standard of Iran and guidelines of WHO. According to the langelier index , Ryzener and Aggressive indexes %87.5 , %66.7 , %84.7 of Bardsir drinking water were precipitated transition respectively. Although microbial and chemical quality of water are according to limits of standards, the circumstances of potentials contamination of the region is necessary and must be continuously monitored.

  Key words: Langelier index- Ryzener index and Aggressive index, Drinking water quality
