<P> In 1973, DuPont engineer Nathaniel Wyeth patented polyethylene terephthalate (PET) bottles, the first plastic bottle to be able to withstand the pressure of carbonated liquids . Today, PET plastic has replaced glass as the preferred material for single - serving bottled water containers due to its light weight and resistance to breaking . </P> <P> Some of the more common types of bottled water are: </P> <Ul> <Li> Artesian water--this is water that originates from a confined aquifer that has been tapped and in which the water level stands at some height above the top of the aquifer . </Li> <Li> Fluoridated--this type of water contains added fluoride . This category includes water classified as "For Infants" or "Nursery ." </Li> <Li> Groundwater--this type of water is from an underground source that is under a pressure equal to or greater than atmospheric pressure . </Li> <Li> Mineral water--water from a mineral spring that contains various minerals, such as salts and sulfur compounds . It comes from a source tapped at one or more bore holes or spring, and originates from a geologically and physically protected underground water source . No minerals may be added to this water . </Li> <Li> Purified water--this type of water has been produced by distillation, deionization, reverse osmosis, or other suitable processes . Purified water may also be referred to as "demineralized water". </Li> <Li> Sparkling water--Sparkling water contains the same amount of carbon dioxide that it had at emergence from the source . The carbon dioxide may be removed and replenished after treatment . </Li> <Li> Spring water--this type of water comes from an underground formation from which water flows naturally to the Earth's surface . </Li> <Li> Sterile water--this type of water meets sterilization requirements, for example, those specified under "sterility tests" in the United States Pharmacopoeia . </Li> <Li> Well water--well water is taken from a hole tapping, etc . This hole may be bored, drilled, or otherwise constructed in the ground . </Li> </Ul> <Li> Artesian water--this is water that originates from a confined aquifer that has been tapped and in which the water level stands at some height above the top of the aquifer . </Li>
