The term bottled water means water packed in a health-correct packaging and available
in the market for human consumption. Consumers still have insufficient knowledge of
importance of the certain ingredients and their harmful or beneficial effect on the human
organism. There is not enough expert information about the harmfulness of certain
ingredients in the water, but many countries in the world have adopted legal regulations
in which quality parameters of bottled water are standardized (EEC, WHO1, EPA,
IBWA, FDA). The race for profit and the lack of necessary quantities of bottled waters
moved declarations in to the second plan. The declaration on bottled waters should
describe also the physiological characteristics, since the consumption of high-mineral
water may lead to adverse effects on the health of consumers, primarily children. In such
declared water, missing physiological characteristics of water, redox statuses, and
possible consequences on the health, are neglected due to excessive consumption of
waters with high mineral content. Due to the increased content of mineral substances
and high sodium intake, the allowed daily intake should be declared for water loaded
with mineral substances. Redox status of water represents a health factor and it is
completely defined by the pH value, redox potential and rH2 factor, parameters which
were the subject of this study in this work. The oxide-reduction potential of water, EROX,
represents the mixed potential of all present redox pairs and directly affects the behavior
of water relative to the agents to which comes into contact2. The results pointed to the
necessity of a fuller declaration of bottled water, because in that case bottled water
gained in importance and would decrease the consequences of the possible bad effects
on health due to excessive consumption of water rich with minerals. Test results
demonstrated that our market has a wide range of bottled waters, and that the health
aspect can be estimated through the oxidation-reduction properties
