Survey results have shown that consumers are concerned about the quality of their drinking water, Health Canada reports. Some people think that bottled water is safer than municipal tap water even though there isn’t any evidence to support and deny this. The studies that have been done conclude that the levels of bacteria found in bottled water increase quickly to maxium levels after six weeks of refrigerated shelf life.
Bottled water labelled mineral or spring water is a potable water that comes from an unground source. For it to be labelled as such it can’t come from a public water supply. Mineral water is defined as water that is spring water with larger amounts of mineral salts, usually about 500 milligrams (Canaidan regulations wheres in the United States it’s 250 milligrams). Both Mineral and spring water must not have gone through a chemical process in order for it to be drinkable. Carbon dioxide and ozone can be added to the water during the bottling process to protect the freshness.
So what are scientists recommending? If you are determined to drink bottled water it’s recommened to drink water that has been ozonated, carbonated or disinfected. All these treatments disinfect the bottled water to eliminate harmful bacteria. People are advised to read labels carefully or write to the bottled water manufacturer to detailed information on the process used. Yea seriously, I dare anyone to shoot out an email to Evian requesting product safety information.
The safest storage. To maintain the purity of bottled water, Health Canada recommends that you refrigerate the smaller bottled water once it’s been opened and preferably once you buy it. If you can’t refriderate bottled water, store it in a cool, clean environment away from heat and sunlight. Although manufacturers give bottled water a best before date or shelf life of two years, it is recommended that you replace the bottles after a year.
Final note on bottled water:
Health Canada is aware of reports apppearing on the Internet regarding concerns about the potential degradation of plastic water bottles left in cars or outside. The allegations are the release of cancer-causing chemicals from the plastic bottles into the water. There is no scientific proof to support these concerns. Studies conducted on water bottles, even under severe temperature abuse conditions have failed to generate the production of chemicals at levels that could pose a health risk to the consumer of the water in question.
