IBWA advises consumers to store bottled water at room temperature or cooler, out of direct sunlight and away from solvents and chemicals such as gasoline, paint thinners, household cleaners, and dry cleaning chemicals.
Why these conditions are best for bottled water storage.
• When water (bottled water or tap water) is exposed to extended periods of direct sunlight or heat sources, algae or mold may infrequently develop. Although this is not a general concern for public health, the bottled water industry wants you to enjoy the freshest, cleanest water possible, and storing water in a cool place out of direct sunlight helps assure that.
• Bottled water and other beverages are packaged in sanitary and highly protective, sealed plastic containers that maintain the quality and freshness of the product. However, plastic containers – whether used for bottled water or other beverages – are slightly permeable, which may allow ambient air gases such as vapors from household solvents, petroleum-based fuels and other chemicals, to affect the taste and odor of your beverage. Your bottled water company takes great care to store and transport its products carefully so you can enjoy the fresh, clean taste you expect from bottled water. Proper storage will help ensure product quality.
