Bottled water is the world's fastest growing beverage, but customers prefer turning on the tap. Water Bottlers generally take advantage of consumer concerns regarding municipal water supplies, hence increasing demand for their product. A number of bottled waters, nonetheless, differ from tap water simply because it is distributed by bottles rather than through pipes (Mark, 2012)
Tap and Bottled water come from basically the same sources: springs, aquifers and lakes, to list a few. Actually, a considerable fraction of the bottled water products on store shelves are tap water although treated and filtered with extra steps to perk up taste (Karlstrom et al., 2010)
Bottled water is not exposed to contagion from lead in built-up pipes. However it may possibly contain compounds that leak out of the plastic bottles, that are usually made of polyethylene terephthalate or PET.
The compound is different from the phthalates which is associated to birth defect in infant; however studies have proved that polyethylene terephthalate can release miniature toxic compounds into water. The amounts are below toxic levels; however when the bottle is left in the sun, microwave or a hot vehicle can speed up the process.
Bottled water does not only contribute to excessive waste, but also costs us a hundred times more than water from the tap, and it is likely cleaner or safer. A nonprofit Environmental Group carried out an investigation and found out that some bottled water is sullied with unproven industrial compounds and may not essentially be cleaner than tap water.
The plastic used in single-use bottles can cause more of an infectivity threat than the water. Safe plastics that are used only once contain one polyethylene terephthalate, a common resin used in bottles that are not reusable. Nevertheless, as the first bottles are used again, as they commonly are, they seep chemicals such as DEHA, a possible human benzyl butyl phthalate and carcinogen a possible hormone disruptor. And since the plastic is absorbent one is likely get a swill of destructive bacteria with each gulp the bottle are reused (Elena, 2008).
(Elena, 2008)
Taking into consideration such facts, bottled water may seem preferable. Nevertheless coming from similar sources such as tap; it is subject to many of the same contaminants. It's held to fundamentally the same standard as tap water.
