A. The problem with bottled water is that BPAs and other dangerous contaminants can leech from the plastic into the bottled water that you drink. These contaminants vary by product and bottled water types as many independent testing have shown. For example, the city of Cleveland carried out tests that showed that its municipal tap water was cleaner, taste better and was safer than Fiji bottled water! Dasani label discloses on each bottle of water that its water contains magnesium sulfate, a drying agent, potassium chloride, commonly used as a fertilizer, and salt. These are chemical agents that you don’t want added to your drinking water, which many consumers of bottled water unwittingly support and accept.
