Chemical quality of bottled water Kristi Vahur, Inga Ploomipuu, Ott Remmer
Abstract Several studies have shown that worldwide consumption of bottled water is increasing. The water used for human consumption must meet the quality requirements. Bottled water that does not follow the regulations can cause various health problems. High quality drinking water, either tap water, water from private wells or bottled water is essential for the well-being of all people. The study of the chemical quality of bottled water is part of an applied research project “Drinking water consumption habits of Estonian residents”. The aim of the research study was to determine the compliance of bottled water sold in Estonia with the quality requirements established by Regulation No. 82 and No. 83 of the Minister of Social Affairs. Laboratory analysis of 24 bottles of water (12 different products, 2 test bottles from each product), out of which 10 were natural mineral waters and 14 bottled drinking waters (4 flavoured waters and 10 non-flavoured waters) was carried out. As a result of the study, it can be said that 42% (25% of the foreign origin) of the bottled water samples did not meet the standards. The quality parameters that were exceeding the limits were manganese, sulphates, chlorides, fluorides, lead and nickel in some cases. The type of bottled water (bottled drinking water or natural mineral water) and carbon dioxide content had no effect on water quality.
