Background: Today, global concerns about water pollution with chemicals and its adverse impact on health have increased. This study aims to evaluate the physical and chemical quality of water treated through domestic water treatment systems.

Materials and Methods: In this cross-sectional descriptive study, water samples were collected from 60 domestic water treatment systems and parameters, such as turbidity, total dissolved and suspended solid, total hardness and calcium, magnesium hardness, alkalinity, total alkalinity, carbonate, bicarbonate, nitrate, sulfate, nitrite and fluoride, EC, pH, and free chlorine residuals, were examined.

Results: The results indicate that the average concentration of chemical parameters in treated water were: chloride=0.1mg/L, nitrate=0.006mg/l, sulfate=5 mg/l, Nitrate=15mg/L, bicarbonate=49 mg/L, calcium hardness=18 mg/L, and fluoride=0 mg/l.

Conclusion: The overall results of this study indicated that the use of municipal water treatment reduced Cl2, sulfate, and bicarbonate concentrations than the optimal levels in urban areas water. However, nitrite concentration was significantly higher in the output of these systems than distribution systems, which is a source of concern.
