The present study illustrates the rapid pollution of Euphrates River, inwards Al-Najaf Al-Ashraf
governance (Al-Kufa River) in Iraq, which is one of the most important rivers in the region. The river
faces formidable pressure due to encroachments, discharge of untreated domestic and industrial waste,
drainage water from cultivated orchards, and dumping of solid waste. This study was conducted to assess
the temporary and locative organic pollution in the region. Water Quality Index (WQI) of the Al-Kufa
river was determined according to the Canadian Council of Ministers of Environment (CCME) method by
calculating seven parameters (water temperature, DO, COD, EC, TDS, turbidity, and pH) in two sampling
stations. Surface water samples were collected in a period of four months (September to December) in
2023. WQI level, correlation analysis between parameters, and Iraqi and CCME drinking water
specification standards were employed to classify the surface water status. The results show that the
ecological condition can be classified as marginal with WQI= 49 and poor with WQI= 42 in stations 1 and
2, respectively.
