Due to various natural and anthropogenic activities, quality of water was deteriorated in most towns of the country. These changes make the community to depend on unsafe and poor water consumption. Under the present investigation some physicochemical parameters of water from Mettu town for drinking purpose was characterized. The analyzed laboratory result of some heavy/trace metals from the town were Zn (from source point, tap and distribution was 0.06429 ± 0.00242, 0.00759 ± 0.00235 and 0.03594 ± 0.00238 respectively), Pb (from source point, tap and distribution was respectively 0.04348 ± 0.04376, 0.11141 ± 0.04450 and 0.07744 ± 0.04413). Among the three heavy metals the concentration of Lead (Pb) recorded was above the maximum permissible limit of lead in drinking water (0.01 mg/L) according to WHO standard. Some selected laboratory result of physicochemical parameters was pH [Ms (6.44), Mt (6.61) & Md (6.32)]. Electrical Conductivity (µS/cm-1) [Ms (274), Mt (259) & Md (267). Turbidity (NTU) [Ms (8.21), Mt (5.63) & Md (5.87). Comparatively the maximum value for almost all physicochemical parameters were recorded at Mettu town which indicates further treatment process needs for this town.
