MINERAL WATER

Mineral water is water from a mineral spring that contains various minerals, such as salts and sulfur compounds. Mineral water may be sparkling, due to contained gases.

Traditionally mineral waters were used or consumed at their spring sources, often referred to as “taking the waters” or “taking the cure" iIn areas such as spas, baths or wells in developed cities. Today it is far more common for mineral water to be bottled at the source for distributed consumption.

Mineral water is a kind of like a vitamin supplement that you can drink. Are there health benefits from drinking mineral water? Are there any risks?

Drinking water purification is a series of steps  to eliminate microoganisms and waste water in oder to obtain purity and quality. "Fonteide" draws water  directly from a spring and  is responsible to analize water  and bottle it. The water is so pure that it is recommended for our health and babies' food.
