Purified and tap Water
Explosive growth in the industry for more than a decade has placed bottled water in nearly every supermarket, convenience store and vending machine from coast to coast, where dozens of brands compete for consumers' dollars. In four years, industry experts anticipate that bottled water will be second only to soda pop as America's beverage of choice. Water, of course, is essential to human health. Drinking enough water to replace whatever is lost through bodily functions is important. In this day and age, it seems like bottled water is becoming more and more popular. It has practically become the icon for healthy beverages. There are approximately 475 bottled water plants in the U.S., producing 600 brands of bottled water. It is estimated that one in six American households use bottled water as either the primary or only source of water.
Bottled water can come from wells, springs, artesian wells, or the municipal water supply. The U.S. Food and Drug Administration (FDA) regulate it as a food product. It is important to note that the FDA’s standards are essentially the same as those set by the U.S. Environmental Protection Agency (EPA), which regulates public water supplies. In some states, however, bottled water requirements are stricter than those for tap water are. Tap water can come from surface water (lakes or streams) or groundwater. Unlike bottled water distributors, public water suppliers usually track cases of water-borne illness. Furthermore, if a contaminant exceeds EPA standards, public water suppliers are required to notify citizens of the contaminant, its level in the water supply, its health effects, and measures that can be taken to prevent illness..............
