Abstract: 

Background and Objectives: Consumption of mineral bottled waters has been considerably increased in the recent years. These waters have some specific mineral and chemical properties which can affect human health. In this study, the quality of bottled waters also known as "mineral bottled waters" are investigated in terms of physical, chemical, and microbial parameters, water hardness, curative properties and also the accuracy of the properties printed on their labels.
Materials and Methods: In this descriptive study, 13 brands of mineral bottled waters, available in Kerman markets, were included to investigate seventeen chemical, physical and microbial parameters. The mean value of each parameter was calculated and compared with the standard values and also with the values printed on their labels. In addition, the water hardness and curative properties of different brands were studied based on their ion concentrations.
Results: The results of this study showed that 54% of waters were categorized as hard or very hard waters. No microbial contamination was found and none of them had curative properties. A comparison between the chemical properties of these waters and the standard values of drinkable and mineral waters indicated that while all tested waters had a fluoride concentration of lower than standard values, the Cl- (50 mg/l) and NO3- (8 mg/l) concentrations were higher than the standard levels in seven percent of samples. Also, the concentrations of K+ and Na+ were higher than the permitted levels in 23% and 46% of the samples, respectively.
Conclusion: The different properties of the mineral bottled waters investigated in this study were consistent with the standard levels. However, even a few inconsistency with standard criteria regarding ion concentrations or other propertis may have a detrimental effect on health status which should be taken into account by relevant authorities. Manufacturers also need to adhere more to all realted standard rules and regulateins.
