| Abstract |
| Heavy metal concentrations from water treatment process to tap water supply are monitored at the two regions of the water treatment plants in this study. The variation trend of Iron(Fe), Zinc(Zn) concentrations showed a gradual increase through water treatment process, distribution reservoirs, water tanks, and a faucet. Especially, Fe and Zn increased dramatically in going through the reservoir and the faucet. It is explained that a seriously heavy metal leaching occurred in plumbing pipe systems. It is found that copper(Cu), lead(Pb), and manganese(Mn) were undetected and there are no differences from the initial concentrations during the water treatment process to the supply systems. |
