Three crucial stations, Kufa, Al-Abbasiya, and Al-Manathera, were used to monitor the water quality of the Euphrates River in Al-Najaf Governorate in 2023 and 2024. The following 14 critical components were assessed pH, dissolved oxygen (DO), nitrate (NO₃⁻), calcium (Ca²⁺), magnesium (Mg²⁺), total hardness (TH), potassium (K⁺), sodium (Na⁺), sulfate (SO₄²⁻), chloride (Cl⁻), total dissolved solids (TDS), electrical conductivity (EC), alkalinity (Alk), and turbidity (turbidity). The mean, standard deviation, maximum, and minimum values for each element were computed for each year. According to the statistics, in 2023, it was discovered that Al-Abbasiya had the greatest values for pH and dissolved oxygen, while Al-Manathera had the highest values for most elements. Kufa station has the lowest dissolved oxygen readings in 2024. Values for the water quality index (WQI) climbed from 81.4-101.6 in 2023 to 150.8-190.2 in 2024 across all stations when the weighted arithmetic index technique was used. This caused the water quality index at the Kufa and Abbasiya stations to drop from "good" to "poor," but Al-Manathera station continued to be categorized as poor by international standards. In order to preserve the river system and guarantee the sustainability of water resources, these findings highlight the urgent necessity for management actions.
