Tap water in Moscow can be drunk even without purification and boiling - its quality is strictly controlled. Elena Stolyarova, chief technologist of the Mosvodokanal water supply department, told RIA Novosti.
The water is thoroughly purified and disinfected at four water treatment stations, the expert assured. “First, it is purified by coagulation followed by clarification in sedimentation tanks, passed through sand filters, and then disinfected with chlorine-containing reagents. If necessary, they are treated with ozone and activated carbon,”Stolyarova clarified.
She also noted that there are various trace elements and organic compounds in the water, and this is normal - the regular use of excessively purified, distilled water is dangerous to health, "because it flushes useful substances from the body."
Stolyarova said that sodium hypochlorite is used in Moscow to disinfect water - and this substance is less toxic than chlorine used until 2012.
Earlier, in December, the Russians were told about the bottled water cheat. It turned out that illustrations depicting natural objects, including mountains, are often placed on labels of tap water treated with chlorine.
