One of the most significant natural resources is water because it is a necessity. It is all of a man's social and economic endeavors across a variety of disciplines. Water differs from other natural resources in that its supply is fixed globally and is replenished over a set time period according to the hydrological cycle. Recent neglect of the severe decline in water sources has resulted in this situation. The Iraqi environment has significantly deteriorated over the past 20 years, beginning with air pollution and ending with soil and water pollution. This is because there are numerous sources of pollution in Iraq's water supply, and there are no plans in place to build and strengthen the infrastructure that will allow for the provision of clean water. As a result of the water pollution in Iraq, drinking water, rivers, surface water, and ground water were also contaminated. The Water Quality Index (WQI) developed by the Canadian Council of Ministers of the Environment (CCME) is one of the tools that academics use the most frequently to evaluate water resources and quantify their contamination levels. The goal of the current study is to use the Canadian Water Mechanism Manual to assess the water quality at five stations along the Shatt Al-Hilla river in the Iraqi province of Babylon. The current research demonstrates how the Shatt Al-Hilla River and five other locations in Babel City, Iraq, were evaluated using the Water Quality Index developed by the Canadian Council of Ministers of the Environment (CCME WQI). The fieldwork was finished in April 2019, between November 2018, and this month. The CCME WQI was built using thirteen factors for measuring water quality (Chromium, Chemical oxygen demand, Lead, Biological oxygen demand, Dissolved oxygen, Turbidity, Sulphate, Nitrite, Nitrate, Total Hardness, Total Dissolved Solids, pH magnitude and Water temperature). The average magnitudes for five stations along the CCME WQI for the Shatt Al-Hilla River ranged from 61.94 to 81.93 depending on the index's findings.
