Abstract

The water quality of the Damietta branch evaluated and assessed using the water quality index (WQI), including twenty-one physical, chemical, and biological parameters (Temperature, Turbidity, Chlorine, Electrical Conductivity, Total Dissolved Solids, pH, Chloride, Total Alkalinity, Total Hardness, Dissolved Oxygen, Chemical Oxygen Demand, Biological Oxygen Demand, Nitrogen, Sulfate, Calcium, Total phosphorus, Sodium, Potassium, Nitrate, Magnesium, and Total Coliform) measured at eleven different drinking water intake stations in Dakahlia governorate along the Damietta branch of the Nile river for four successive years from 2018 to 2021. The scale for evaluating the water quality of the Damietta branch of the Nile River is created using the tolerance limits of Egyptian law “regarding the protection of the Nile River and waterways from pollution”, Law No. 48/1982, and its regulations No. 92/2013. The water quality index approaches: Weighted Arithmetic (WA-WQI) and the Canadian Council of Ministries of the Environment (CCME-WQI) are used to find WQI in Dakahlia Governorate along the stretch of the Branch. The Damietta branch of the Nile River indicates good and excellent suitability for surface water use according to the tolerance and permissible limits of Egyptian law and regulations.
