In the framework of assessing the applicability of RBF "River Bank Filtration" technique in Iraq, this research was originated in order to validate its applicability against International Standards, where CCME-WQI "Canadian Council of Ministers of the Environment Water Quality Index" was selected. A previous research results were adopted [1]. Principally, literature was reviewed in the field of RBF applicability verification. The results of the previous research were implemented to calculate the Canadian index, where 17 parameters were selected. These were Turbidity, No2 , So4 , TDS, F, NH3 , Cl, Fe, Res cl, pH, DO, Alkalinity (Caco3), Total Hardness (Caco3), Ca, Mg, Mn and No3. Results were obtained; analyzed and plotted on graphs. From the graphs, apparent was that the WQI values ranged between 87 and 100, which indicated that the WQ "Water Quality" is within the acceptable range of the Canadian Standards that ranked the water quality, as "Excellent". Confident with the validation of RBF applicability, it was further recommended to inspect its sustainability.
