Canton has bottled and bulk water available for sale. Bottled water is water, which may be well water, spring water, or distilled and treated water, packaged in plastic bottle. It may or may not be "fizzy", depending on whether it is carbonated or not. These can be bought as they are treated and packaged to stringent safety standards to ensure minimal risk of water borne diseases. The bottles can be of various volumes, such as 330 ml, 500 ml, 1l, or 1.5l. Larger sizes may also be available. Packs of such bottles may also be bought. It may be worthwhile to note that USA is the largest consumer market for bottled water in the world. Bulk water, sold in Canton is water packaged in much larger quantities, which are transported by tank trucks. These are often used at commercial establishments such as offices and restaurants. These tankers have to be standardized and sanitized for carrying water (which is potable in nature). Bulk water is regulated by the government at the state level. Bulk haulers are certified, and such certification is renewable.
