Public perception of bottled drinking water as the cleanest and safest source of drinking water in the world and particularly Ghana, has led to their increasing demand though being pricey. In this study, we present the results of the health-related trace elements (As, Cd, Cu, Pb and Zn) in 10 selected popular bottled drinking water brands sourced from Accra metropolis, Ghana. These include BonAqua Premium drinking water, AquaSplash purified noncarbonated drinking water, Safina natural mineral water, Bel-Aqua natural mineral water, EcoSpa natural mineral water, US drinking water, Special Ice natural mineral water, Everpure purified drinking water, Privada natural mineral water and Voltic natural mineral water. The analysis was achieved by using Atomic Absorption Spectrometry and Arsenic field test kit. The results revealed that all the 10 selected bottled drinking water had values ranging from BDL for (As), <0.02 (Cd), <0.05 (Pb) and <0.05 (Zn). However, Cu values largely varied throughout all the samples ranging from 0.0675 (BonAqua Premium drinking water), 0.075 (AquaSplash purified noncarbonated drinking water), 0.0674 (Safina natural mineral water), 0.0731 (Bel-Aqua natural mineral water), 0.0924 (EcoSpa natural mineral water), 0.0888 (US drinking water), 0.0593 (Special Ice natural mineral water), 0.0843 (Everpure purified drinking water), 0.0954 (Privada natural mineral water) to 0.0848 (Voltic natural mineral water). Therefore, this postulates that As, Cd, Cu, Pb and Zn pose no health risks as they are below the World Health Organisation and Ghana Standard Board’s guidelines. We recommend that more extensive surveillance of the bottled water industry as well as stringent regulations be developed and enforced to ensure that this admirable compliance rate is maintained.
