Evaluation of some limno logical properties in Euphrates river within AL-Anbar province, Iraq

The physical and chemical properties of water are important in determining the suitability of water for various uses on the one hand and knowing the level of environmental pollution of this water on the other hand. This study aims to reveal the level of pollution occurring in the waters of the Euphrates River through these characteristics, and to identify the sources of this pollution. During the period from April ۲۰۲۲ to March ۲۰۲۳, water quality of Euphrates River was examined between Ramadi and Al-Qaim cities. The examined parameters include Temperature, Total Suspended Solids (TSS), Electrical Conductivity (EC), pH, Total Dissolved Salts (TDS), Salinity, Calcium, Sodium, Chloride, Bi-Carbonate, and Sulfate. The obtained values of such parameters were compared with the standard values of World Health Organization (WHO). While most of the measurements were within the allowable range, some values exceed the limits of WHO regulations such as EC and TDS values in Ramadi city which reached to ۱۲۴۵.۵۳±۱۱۷.۴۷ µS/cm and ۷۹۳.۱۷+۴۶.۴۱ mg/l respectively. However, correlation coefficient between the involved parameters was examined related to location and time. In conclusion, river pollution levels were varied from one region to another within the study area through the under-study parameters, as river water is generally suitable for irrigation but not drinking without pretreatment processes.
