Some big water companies in France, like Perrier, have problems now. People are worried about the water because of climate change and not enough rain. The companies used special filters to clean the water, but this is not allowed for “natural mineral water” in Europe.

The government and the companies tried to keep this problem secret. Now, many people know about it. The water is still safe to drink, but the rules say the water must not change from the source to the bottle. If the companies use filters, they cannot call it “natural mineral water” anymore.

Perrier and other companies may not be able to use the name “natural mineral water” soon. They are waiting for a decision. The company now uses a different filter and only asks for the special name for some of its water. People are watching to see what will happen next.
