Bottled Water

Bottled water is filtered drinking water packaged in plastic or glass containers. The most popular form of retail packaging for water is the relatively new Polyethylene terephthalate bottle. Another type of packaging is larger high-density polyethylene plastic bottles, or polycarbonate plastic bottles often used with water coolers. Bottled water has reduced amounts of copper, lead and other metal contaminants since it does not run through the plumbing pipes where tap water is exposed to metal corrosion

Artesian water comes from a well tapping a confined aquifer in which the water level stands at some height above the top of the aquifer. It is with the assistance of external force to enhance the natural underground pressure. Water that has gone through distillation, deionization, reverse osmosis or another similar process, such as demineralization is also known as purified water. Sparkling water contains the same amount of carbon dioxide that it had at emergence from the source, although it may undergo removal and replenishment during treatment. Spring water must come from an underground formation from which water flows naturally to the Earth's surface. Sterile water meets the requirements under "sterility tests" in the United States Pharmacopoeia.
