What is Mineral water?
[[File:Mineral water Goryachiy Klyuch.jpg|thumb|Mineral water]] '''Mineral water''' is water obtained from [[Rock (geology)|rocks]]. It is often collected from [[Spring (water)|spring]]s or from underground [[river]]s when they emerge from the rocks. Mineral waters are very clean and have no [[Microorganism|germs]] in it. Because they have been held in rocks for a long time they often contain [[chemical]]s that have come from the rocks. This chemicals can give the water an interesting [[taste]]. Some mineral waters may be good for [[health]]. Because some underground water comes to the surface from very deep layers in the earth, it can also have [[carbon dioxide]] gas dissolved in it. This can make the water fizzy. {{food-stub}} [[Category:Drinking water]]
