The Kabul river water has been investigated with respect to temperature, pH, conductivity, chloride, sulfate, total alkalinity, total hardness, nitrate, nitrite, ammonia, phosphate, DO, BOD, GOD, and sulfide during high flow conditions between June-August 1993. These values have been compared against standards for the maintenance of fisheries and aquatic life. Two major water quality issues have emerged from this river water survey. These are; organic water pollution, particularly in the Shah Alam branch and lower main river, and sulfide concentration especially in the naguman and Shah Alam branches and lower main river.
