Rivers are more exposed to secondary pollutants than other water sources (groundwater) due to the entry of some pollutants from the activities of human communities. Investigating the quality of the water transfer canal of the southeast treatment plant is of special importance due to the supply of drinking water to the cities of Mahshahr, Bandar Imam and petrochemical industries, other administrative and commercial subscribers of Bandar Imam. In this study, physicochemical and microbial quality parameters including temperature (T), electrical conductivity (EC), total soluble solids (TDS), turbidity (TUR), acidity or alkalinity (pH), water hardness (TH), calcium ( Ca), magnesium(Mg), chloride (Cl-), carbonate (Co2-3), bicarbonate (Hco-3), sodium (Na), potassium (K), chemical oxygen demand (COD), sulfate (SO4 an‎d fecal coliforms were applied along the southeastern water transfer canal from Kot Amir to Sarbandar. .Accordingly, during the period of November 1997 to May 1998, during field operations, quality samples were taken twice a month and each time two quality samples were taken from 5 points along the southeast water canal and a total of 60 quality samples. Water classification in terms of agriculture, drinking and industry was performed based on qualitative analysis through Wilcox, Schuler, and Piper diagrams, and finally, using NSFWQI index, water quality classification was performed. It was acceptable to review the test results and diagrams regarding water quality from the drinking water in the classroom. Also, using the NSFWQI index, water quality along the canal path is average.
