[[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'.) Springs that contain large amounts of dissolved [[sodium]] [[salts]], mostly [[sodium carbonate]], are called 'soda springs'. Many resorts have developed around mineral springs and are known as [[spa towns]]. Mineral springs are alleged to have healing properties. Soaking in them is said to result in the absorption of the minerals from the water. Some springs contain [[arsenic]] levels that exceed the 10ppb World Health Organisation standard for [[drinking water]].<ref name=likang /> Where such springs feed rivers they can also raise the arsenic levels in the rivers above WHO limits.<ref name=likang>{{cite journal |last1= Li|first1= Chaoliu|last2= Kang|first2= Shichang|last3= Chen|first3= Pengfei|last4= Zhang|first4= Qianggong|last5= Mi|first5= Jue|last6= Gao|first6= Shaopeng|last7= Sillanpää|first7= Mika|title=Geothermal spring causes arsenic contamination in river waters of the southern Tibetan Plateau, China|url= |journal= Environmental Earth Sciences|year= 2014|volume= 71|issue= 9|pages= 4143–4148|doi=10.1007/s12665-013-2804-2|bibcode= 2014EES....71.4143L|s2cid= 128479153|access-date=}}</ref> | [[Mineral]]s become dissolved in the water as it moves through the underground [[rock (geology)|rocks]].

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.
