Is it true that more regulations apply to tap water than to bottled water?

Tap water has to be chemically treated to meet drinking water standards. Natural mineral water is endowed with a natural purity and therefore must not be treated. But to be recognized by the health authorities (DDASS in France) as a “natural mineral water” it must undergo certain tests nevertheless.

Can I drink natural mineral water every day?

Natural mineral waters with a low mineral content like Wattwiller can be drunk every day by all family members. With natural mineral water you won’t have any unpleasant surprises or a risk of impurities and food security is guaranteed. Water with high mineral contents should be drunk occasionally, alternating with other types of water, in order to take a surplus of particular minerals when necessary, for example to compensate for a temporary deficiency.
