摘要

The physical, chemical and microbial quality of bottled water, tap water and water supplied from wells in the city of Shahroud was compared. The results of the analysis showed that the measured parameters, except in minor cases, were of national and international standards. There was no significant difference between the quality of bottled water and tap water, as well as bottled water and water available in water supply resources in the city of Shahroud. Regardless of the area in which the study was conducted, it was found that there was no need for developing other types of water treatment systems such as bottled water and domestic water treatment systems. In many cases, since bottled water is exposed to intense sunlight during the transport process, there could be a leakage of plastic monomers from the bottle wall into the water in hot or cold conditions, which can endanger consumer health. Tap water supplied from the water supply resources in the city of Shahroud was found to be completely safe and posed no threat to consumer health.
