Bottled water is perceived by many people of Pakistan and other countries as well a safer alternative to other sources of water such as tap water. This may be attributed to consumers disliking the taste of tap water or it's organoleptic. Bottled water usage has increased even in countries where clean tap water is present such as in Germany, Kuwait and Saudi Arabia etc. The objective of present study was to compare the drinkable bottled water quality between different countries along with ZamZam water. Eleven different brands of bottled water including one un-bottled water (zamzam) collected from Pakistan, U.A.E, Kuwait, Germany and Saudi Arabia. They were analyzed for physiochemical and microbiological parameters for estimation of quality of water. For physio-chemical analysis, the pH meter, EC meter, Flame photometer and UV-Spectrophotometer were used respectively. For bacteriological parameters like Total Coliforms, Fecal Coliform and E. coli, filtration technique is adopted. In this study, comparison of mineral contents with labeled values mentioned on different brands of the countries like Rawdatain(Kuwait), Al-Ain(UAE), and Masafi (UAE) which have difference in actual measured values and labelled but all within WHO and IBWA standards. Bottle water companies claim, the water from different sources such as spring, deep ground and natural water but no doubt it may be taken from different natural sources and they are saying it a mineral water when it was not pass through any treatment processes. These bottles water are actually processed/treated water which does not contain sufficient amount of minerals necessary for the health.

“…Ozonation, reverse osmosis, distillation, and de‐ionization are common treatment methods of bottled water. Ozonation can be used for disinfection, removal of manganese, organic micropollutants and can improve the color, taste, and odor of drinking water (Schneider and Rump ; Kruithof and Masschelein ; Kuo and Chan ). However, the oxidation of organic matter in drinking water by ozone may result in different types of disinfection by‐products, some of which are known or suspected to be carcinogenic or harmful in other ways (Richardson ; Richardson and others ; Huang and others ; Kim and Hyun ).…”

The worldwide consumption of bottled water has experienced an annual increase of 5.5% since 2004 and different authors have speculated that this is due to beliefs of superior flavor and health qualities of bottled water over tap water. The content of certain minerals varies by 2 to 6 orders of magnitude between bottled water brands. The major cations Ca, Mg, Na, and K can be found in concentrations up to 730, 450, 1900, and 270 mg/L but are usually below 100 mg/L; higher concentrations have only been found in some European and North American bottled water samples. The dominating anions are HCO 3 − , Cl − , and SO 4 2− . Sensory evaluation and description of water strongly depend on personal preferences and sensitivities. The major cations can be detected by taste in concentrations down to 2 digits in the mg/L range; however, the intensity depends on which anions are present. Most cations add different degrees of salty, sour, sweet, and bitter tastes to water depending on their concentrations. Al, Ca, Cu, Fe, Mg, and Zn may introduce metallic, astringent, and irritative sensations and for Fe and Cu also retro-nasal odors may influence the metallic sensation. Drinking water with total dissolved solids in the range of 100 to 400 mg/L results in good sensory quality. Known offflavor problems originate from by-products of ozonation and leaching of organics from bottling material which may also be enhanced by ozonation, and microbial by-products from the source water such as geosmin and 2-methylisoborneol, lubricants, or cleaning agents used in the bottling industry.
