The concentration of total iron is one of the main physicochemical indicators of the safety and quality of tap water. The standard amount of the concentration of common iron in tap water is not more than 0.2 mg/dm3. In some cases, due to specific natural conditions and technology for drinking water preparation/treatment, this number may be increased to 1.0 mg/dm3. Excess iron concentration in the water adversely affects the skin, blood composition, etc. Prolonged consumption of water with high iron concentration leads to liver disease, causes allergic reactions, etc.
