During the summer and winter seasons of   2014 and 2015, a total of 14 samples (7 samples in winter and 7 in summer) was collected from 7 sampling points as follow: Damietta branch,  El-Serw drain, El-Salam canal after mixing with El-Serw drain, Bahr Hadous drian,  El-Salam canal after mixing with Bahr Hadous drain, El-Salam canal at El Assafra Bridge and El-Salam canal before El-Sahara. The aim of this research is to study the extent of water contamination in Elsalam canal west of Suez Canal as a result of mixing drainage water with Nile water. The results showed that the chemical analysis (salinity and alkalinity) of the studied locations of El-Salam canal differs due to the ratio of mixed the drainage water with Nile water and also differs in different seasons ( summer and winter ).  Higher values of heavy metal ions (Fe²⁺, Zn²⁺, Mn²⁺, Cu²⁺, Cd²⁺ and Pb²⁺) were noted after the second mixed stage compared with the first stage at Damietta branch, especially in summer season. It is necessary to note that periodically monitor the water of El-Salam Canal is recommended to avoid the risks results on the surrounding agricultural environment.
