Traditionally, mineral waters were used or consumed at their spring sources, often referred to as "taking the waters" or "taking the cure," at developed cities such as spas, baths, or wells. The term spa was used for a place where the water was consumed and bathed in; bath where the water was used primarily for bathing, therapeutics, or recreation; and well where the water was to be consumed.
Active tourist centres have grown up around many mineral water sites since ancient times, such as Hungary, Hisarya (Bulgaria), Bílina (Czech Republic), Vichy (France), Jermuk (Armenia), Yessentuki (Russia), Spa (Belgium), Krynica-Zdrój (Poland), Sulphur Baths (Tbilisi, Republic of Georgia), Bath (England), or Karlovy Vary (Czech Republic), Myrhorods'ka (Ukraine). In Romania, a country enjoying a privileged position as home to over one-thirdof the European mineral and thermal springs, resorts developed since antiquity in places such as Băile Herculane, Geoagiu or Slănic. Tourist development resulted in spa towns and hydropathic hotels (often shortened to "hydros").
In modern times, it is far more common for mineral waters to be bottled at the source for distributed consumption. Travelling to the mineral water site for direct access to the water is now uncommon, and in many cases not possible (because of exclusive commercial ownership rights). There are more than 3,000 brands of mineral water commercially available worldwide.
The U.S. Food and Drug Administration classifies mineral water as water containing at least 250 parts per million total dissolved solids (TDS), originating from a geologically and physically protected underground water source. No minerals may be added to this water. In many places, however, the term "mineral water" is colloquially used to mean any bottled carbonated water or soda water, as opposed to tap water.
In the EU, bottled water may be called mineral water when it is bottled at the source and has undergone no or minimal treatment. Permitted is the removal of iron, manganese, sulphur and arsenic through decantation, filtration or treatment with ozone-enriched air, in so far as this treatment does not alter the composition of the water as regards the essential constituents which give it its properties. No additions are permitted except for carbon dioxide, which may be added, removed or re-introduced by exclusively physical methods. No disinfection treatment is permitted, nor is the addition of any bacteriostatic agents.
