Bottled water comes from sources such as wells, springs, artesian wells, and the municipal water supply. It typically undergoes a purification process before being packaged in plastic or glass bottles. Bottled water can be categorized into mineral water, still water, flavored water, and sparkling water. However, its two primary forms are still and sparkling. Still water is similar to ordinary tap water and has not undergone any carbonation. Sparkling water, also known as carbonated water, soda water, seltzer water, or fizzy water, is water that has been artificially carbonated.
