The present work describes the application of Canadian Water Quality Index (CCME WQI) was applied using six located along with Al-Hilla River water quality parameter (pH, turbidity, electric conductivity, total alkalinity, total hardness, Ca, Mg, Cl). Physic-chemical parameters were monitored for along Euphrates river were monthly monitored during the study to compute the WQI in order to assess the suitability of the river water for drinking and human consumption the calculation of WQI for Winter, Spring, Summer, and Autumn seasons from August ,2013 to August, 2014, Based on the results obtained from the index, the water quality of River ranged between 60-65 which indicate that river has the marginal quality due to effect of Al-Hilla various urban pollutant sources.
