Bottled waters are not all created equal. In Canada they are classified under one of the following labels:
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 comes in both still waters and carbonated waters.
Drinking water – this type can be from any source – usually municipal – that has been purified by 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.
