The self-purification ability of river water was investigated on the two rivers in the northern parts of Kobe city, and the following results were obtained. 1. While the river water of the Arima goes about 4.5 km downstream, the COD and BOD value were decreased by 78.0% and 83.3%, respectively. 2. For increasing BOD value, a definite amount of glucose was added in the river water of the Shijimi. While going about 4.5 km downstream, the BOD value and glucose amount were decreased by 63.9% and 72.7%, respectively. 3. According to the measurement of the decrease of glucose amount in the river water by jar test, it was proved that 15 m^3 of air were consumed to decompose 1 g of glucose.
