Abstract: The purpose of this research paper was to evaluate the quality of the Tigris River and surface water in the state of Wasit, Iraq, over the period of January to November 2024. Water samples were collected from five areas along the river and water from 5 wells. The collected water samples at each site have been sent to the Wasit Central Laboratory for physical, chemical, and microbiological testing. Water quality index was calculated from the collected water samples for assessing the water quality. The results indicated that the WQI of surface water in the Tigris River in the autonomous region ranges from 352.3 to 1106.5, which is 2.0 and 6.3 times larger than the WQI standard, ranging from 301.3, which is. The standard is large, 1.5 and 1.7 times more than WQI. Results indicated that the quality of groundwater is the best in comparison with river quality. Deterioration of water quality in the Tigris might be linked to the discharge of partially treated wastewater.
