Morali, Akkopru, and Kurbas Rivers are rivers flowing into Van Lake passing through the highly populated Van City, Turkey. They carry domestic and industrial wastewater to Van Lake. For assessment of the environmental load from these rivers to the lake, a sampling investigation from October 2019 to September 2020 was carried out. Chemical oxygen demand, biochemical oxygen demand, and nitrogenous compound levels were also examined. Linear alkylbenzene sulfonates ranged up to 0.40 mg L⁻¹ (Kurubas River), the mean phosphate was 0.96 mg L⁻¹, and the mean boron 1.2 mg L⁻¹. According to Turkish surface water quality regulations, while Morali and Akkopru Rivers were determined as class II (less contaminated), Kurubas River was found as class III (polluted).
