Mineral waters

These are natural waters with higher concentrations of various mineral substances (less frequently organic), gases capable of acting beneficially on the human body. There are many known mineral waters. Nitrogen, where nitrogen makes up at least 90 volume percent of all gases; bromine, where the concentration of bromine is not less than 25 mg/l (according to water mineralization – 10 g/l); high temperature, more than 42 °C; bicarbonate, where among the HCO₃ anions there are at least 70 eq. percent (other anions less than 20 eq. percent); sulfide, where hydrogen sulfide and hydrosulfide ion make up 30-70 percent of all sulfides, with water pH from 6.5-7.5; hydrosulfide, where the hydrosulfide ion makes up at least 70 percent of all sulfides, with water pH greater than 7.5; iron-containing, where the iron concentration is not less than 20 mg/l; iodine-containing, where the iodine concentration is not less than 5 mg/l (according to water mineralization – 10 g/l); iodine-bromine, where iodine is at least 5 mg/l, bromine – 25 mg/l; acidic, their pH <6.8; acidic sulfate, containing iron and other metals, formed in polymetallic ore mines; methane, where methane is at least 80 volume percent of all gases (other gases no more than 10 volume percent); marine, formed from seawater in underground basins; arsenic, where the concentration of arsenic acid and its dissociation products is not less than 0.7 mg/l or arsenic is not less than 0.7 mg/l; potable medicinal table, with mineralization – 2-12 g/l; potable medicinal, with mineralization more than 12 g/l (higher in boron, lower in arsenic and other concentrations); radioactive (radon), where radon is at least 5 nCi/l; hydrogen sulfide, where hydrogen sulfide is at least 70 percent of all sulfides, and hydrogen pH is not greater than 6.5; sulfate, where the SO₄ ion makes up less than 70 eq. percent, and other anions – less than 20 eq. percent; sulfide, where the concentration of sulfides (H₂S, HS) is 10 mg/l; carbonic acids, where carbon dioxide (CO₂) is at least 80 volume percent of all gases; chloride, where there are at least 70 eq. percent of chloride ions, and less than 20 eq. percent of other ions; alkaline, with pH > 7.2.
