The aim of this study is to investigate the water quality of the Malaysian bottled drinking and mineral water in terms of Water Quality Index (WQI) and the presence of heavy metals. The water samples were analyzed in the lab to investigate the pH, DO, BOD, COD, TSS and AN as well as the presence of heavy metals. The results for Water Quality Index (WQI) for the water samples were compared with the DOE-Water Quality Index Classes and the INTERIM National Water Quality Standards for Malaysia to know the class of each brand of bottled drinking and mineral waters. The results show that the water quality of each brand of bottled drinking water was in Class I while the water quality of each brand of bottled mineral water was in Class II. Meanwhile, the results for heavy metals were compared with Standard for Water and Packaged Drinking Water by Food Act 1983 (Act 281) & Regulations and Drinking Water Quality Standards by Ministry of Health Malaysia. The results show that all brands of bottled drinking and mineral water contains aluminium (Al). Two brands of drinking water and one brand of bottled mineral water contain copper (Cu), one brand of bottled drinking contain iron (Fe) and one brand of mineral water contain cadmium (Cd). All the metals found in all brand drinking and mineral waters are within maximum permitted value as in Standard for Water and Packaged Drinking Water by Food Act 1983 (Act 281) & Regulations and Drinking Water Quality Standards by Ministry of Health Malaysia. One brand of the bottled mineral water posses cadmium content which exceed the maximum permitted value. 2009 Thesis https://ir.uitm.edu.my/id/eprint/100062/ https://ir.uitm.edu.my/id/eprint/100062/1/100062.pdf text en public degree Universiti Teknologi MARA (UiTM) Faculty of Applied Science
