The present study aimed to assess the chemical quality of the bottled water distributed in Gorgan, Iran.<br> <strong>Methods: </strong>This cross-sectional, descriptive-analytical study was conducted on the samples of bottled water distributed in Gorgan city. Sampling was performed during four months (one sample of each brand obtained every month; total: 36). The chemical quality of the samples was measured using standard methods.<br> <strong>Results:</strong> The mean concentrations of nitrate, fluoride, and iron and mean pH of the samples were 12.92 &plusmn; 11.05, 0.33 &plusmn; 0.12, and 0.64 &plusmn; 2.9 mg/l and 6.89 &plusmn; 0.39, respectively. Only the physicochemical parameters of pH and iron were significantly higher than the standard values, and the mean levels of the chemical factors were significantly lower than the standard values (<em>P </em>< 0.05).<br> <strong>Conclusion:</strong> Consumers expect bottled water to have higher quality as they perceive the product to be a healthier choice than the water supplied by urban distribution networks. High levels of some chemical parameters could adversely affect the health of consumers, especially vulnerable populations, which should be taken into consideration by custodians and authorities.</span></span></div> Bottled water, Chemical quality, Gorgan city 66 71 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-241-1&slc_lang=en&sid=1 Mahdi Sadeghi dr-sadeghi@goums.ac.ir 10031947532846009702 10031947532846009702 Yes Department of Environmental Health and Engineering, Environmental Health research Center, Faculty of Health, Golestan University of Medical Sciences, Gorgan, Iran.
