Joseph, I strongly recommend the water added with ozone. People may add Ozone to spring or mineral water during the bottling process as a disinfectant to inhibit the growth of harmful microorganisms. It also helps in getting rid from the unwanted odor and taste of the water. When choosing a bottled water, examine the bottle and label for date of manufacture or manufacturing code, chemical analysis, treatments applied, company information and the location or type of water source. Examine the bottles to be sure that the seals are not broken and the water is clear and free of debris. Report suspicion of any tampering or extraneous material to the store manager, the Canadian Food Inspection Agency and/or regional health officials. Moreover this there is nothing you can look into while purchasing a bottle. But make sure that while traveling get information about good company of the area and then purchase bottled water.
