Although many consumers believe bottled water is safer than tap water, this is not generally the case. A recent study revealed that a large percentage of bottled water is simply tap water in a bottle sold at a 100 to 1,000 times the price. For example, a typical gallon jug of bottled water ranges from $0.99 to $4 compared to just over half a cent for a gallon of PGUD tap water.
The quality of bottled water can also greatly vary depending on its source, production process, packaging material, and shelf-life before use. Until 1993, there were no proposed federal standards for bottled water and in many states it was unregulated. It wasn’t until 1996 that bottled water was required to meet many of the same regulations as tap water.
