 Introduction: People rely on the quality of the bottled drinking water, expecting it to be free of microbial contamination and health hazards. Objectives of a comparative study of microbiology, chemistry, and physics on the quality of bottled water samples from different countries.  Methods: All bottled water samples sold and collected. Electrical conductivity, total dissolved solid, pH, calcium, nitrate, total aerobic and anaerobic count, coliform bacterial count and fecal contamination were checked. Results: These are 34 brands of bottled drinking water was used. The sample most type of bottled water sample shows an increase in mineral results was 33, 45 and 46, NO3, Fe, NO2, and F was within normal range in all samples. The biological and bacteriological test was almost normal in all samples, heavy metals show an increase in most of the study sample. Conclusions: The bottled drinking water available for sale do not meet the standards stipulated, it is necessary to check the sample from each brand
