| [[Mineral]]s become dissolved in the water as it moves through the underground [[rock (geology)|rocks]]. This mineral content is measured as [[total dissolved solids]] (TDS). This may give the water flavor and even [[carbon dioxide]] bubbles, depending on the nature of the [[geology]] through which it passes. This is why spring water is often bottled and sold as [[mineral water]], although the term is often the subject of [[deception|deceptive]] [[advertising]]. Mineral water contains no less than 250 parts per million (ppm) of tds. Springs that contain significant amounts of minerals are sometimes called '[[mineral springs]]'. (Springs without such mineral content, meanwhile, are sometimes distinguished as 'sweet springs'.)

| Water from springs is usually clear. However some springs may be colored by the minerals that are dissolved in the water. For instance, water heavy with iron or [[tannins]] will have an orange color.<ref name="USGS"/> | Water from springs is usually clear.
