United Arab Emirates standards:
Natural mineral water (in arabic: مياه معدنية طبيعية ) maintains the same mineral content and the same microbiological content from the source.
Bottled drinking water (in arabic: مياه شرب معبأة ) is usually purified via reverse osmosis; and sometimes by distillation. Both of these processes practically eliminate all minerals from the water. Then, the basic chemicals such as calcium and magnesium are added back.
