Assessment of the quality and safety of bottled drinking water

Abstract

The Irkutsk market of bottled drinking water was studied. The quality of four water samples of local producers, which occupy 35% of the market, was assessed. Organoleptic (smell, taste and after-taste, color, turbidity) and physicochemical (total mineralization, hardness, pH, content of sodium, potassium, selenium, chlorides, sulfates, hydrogen carbonates, anionic surfactants) quality indicators of the studied water samples, as well as safety indicators (content of heavy metals, radioactive, organic, and chemical substances) comply with regulatory requirements. In terms of organoleptic indicators, the water of the brand "Wave of Baikal" proved to be the best.
