This research focused on determining the concentrations of heavy metal ions to assess the environmental pollution rate of water desalination plants in western Libya and to know the negative effects of them and their direct impact on the surrounding environment. On this basis, Six samples were collected from the sea water of the Libyan West Coast stations, which are Zuwara, Zawia and Al-Khums stations, where a sample was taken from the incoming sea water and the return water after the desalination process from each station and analyzed the heavy elements such as calcium, magnesium, sulfates, chlorides, potassium, sodium and iron for all these samples. Through the laboratory results obtained, It is clear that there is pollution in the water of the Zuwara station, Zawia and Al-Khums, where the main reason for the pollution of the waters of its seas is due to returning the water consumed in the desalination process to the sea. In addition, the products and waste of the power plant and the Zawia oil refinery near the Zawia desalination plant and The Mellitah Company. The industrial plant near the Zwara desalination plant and the power plant near the five-desalination plant. In addition, the sewage outfalls that flow near these stations have serious negative environmental effects on the results of desalination of the water of these stations
