Not all bottled waters are created equal. In Canada, they fall into one of the following categories, which has to be indicated on the label:
Spring water – Comes from an underground water source (not a public community supply). It should contain fewer than 500 parts per million of total dissolved solids.
Mineral water – Also comes from an underground source but has more than 500 parts per million of dissolved solids. This type of water comes in still and sparkling form.
Drinking water – This type of bottled water can come from any source, usually municipal, and has been purified by a process like distillation, deionization or reverse osmosis.
Carbonated spring water – Water that contains natural or added carbonation from a spring. It has a lower mineral content than mineral water. Soda, seltzer and tonic water are soft drinks, not bottled waters.
