kivennäisvesis
Kivennäisvesi, often translated as mineral water, is water sourced from a natural underground reservoir or underground spring, characterized by its mineral or other dissolved substances content. It is distinguished from ordinary drinking water by the presence and relative proportions of these dissolved minerals and trace elements. The composition of mineral water is determined by the rocks and soil it passes through, and can vary significantly depending on the geographical source. Some mineral waters are bottled at the source, while others are treated to remove certain impurities or to add carbonation. The presence of specific minerals can impart a particular taste and can also be associated with perceived health benefits, though scientific evidence for many of these claims is often limited. In many countries, mineral water is subject to specific regulations to ensure its purity and composition. It is a popular beverage worldwide, consumed both for its taste and its perceived healthful properties.
