The healthiness of drinking water from physical, chemical and biological aspects plays an important role in the health of consumers. The presence of some chemicals in concentrations higher than the standard can endanger the health of consumers in long-term exposure.

This study is a cross-sectional descriptive study and was analyzed using library, internet, article and other information systems in recent years.

There were relative changes in nitrates, heterotrophic bacteria and trihalomethanes, but most of the water smell and taste problems in the distribution system are due to the materials that make up the pipelines or are caused by the growth of biological agents on the pipe walls. to be Musty-earthy smell is the main cause of complaints about the distribution system. Although actinomycetes and fungi are usually responsible for these odors, many heterotrophic bacteria can also cause similar problems

Although nitrate has been increasing with the passage of time, it is within the permissible and acceptable limit. The main current problem is the smell and taste of the water in the distribution system, which must be controlled, and since the fluoride is less than the optimal level, it can be said that the water quality of Tabriz city has the necessary standard due to the attention to the correct and effective management of water resources.
