26. The value of two stars was given to labels either with generic information about the source or because they do not clearly specify their general features and the possible therapeutic peculiarity.

27. On the basis of a strange regulation, mineral water is free from declaring probable undesirable compounds. In fact, there is no limit for manganese nor for other minerals like iron, chromium, sodium, magnesium, mercury, beryllium, etc.

28. Only for drinkable water there are upper values witch can’t be overcome and “guide values” which can be advised
