Background and Objectives: Population growth and limited access to fresh water and need to use bottled water for drinking, chemical and biological quality of the water exacerbates the need for review. The aim of this study was to evaluate chemical and microbial quality in multi-brand bottled water was consumed in the country.
 
Materials and Methods: A descriptive cross-sectional study carried out in stages, the first brand of bottled water available 6 recognized and sampling was conducted.  The chemical and bacteriological quality of water parameters include cL-, nitrate,Mg+2, Ca+2, hardness, Na+,No2-, pH , TDS, EC, F-, total coliforms and fecal coliforms in the samples were tested. The average value of each property, with standard and were compared with the amounts listed on the label. Data analysis using the software SPSS, descriptive statistics and analysis of variance (p <0.05) were performed.

Results:The results showed that the number of total coliform and fecal coliform bacteria group does not exist in any of the samples and MPN /100cc, respectively. The average concentration of chemical parameters such as pH, TDS, calcium, nitrate and nitrite in all bottled waters, were on the standard ranges. As well as in a number of instances, significant differences between the measured values ​​with the values ​​printed on the label of bottled water there.

Conclusion: According to the results obtained, chemical and biological quality of bottled water is examined in terms of acceptable drinking water standards.
