Changes of Water Quality at Dowon-chon of the Dongjin River

This study was performed to investigate the stream water quality characteristics according to the seasonal variation at Dowon-chon of the Dongjin river. Water samples were taken during 15 months from May in 2004 to July in 2005. The measured pH, EC of the stream water was ranged $6.49{\sim}7.22,\;21.0{\sim}173.4{\mu}S/cm$. The concentration of T-N, T-P, COD, SS, DO, BOD were $2.14{\sim}8.93mg/L$, $0.01{\sim}0.39mg/L,\;1.22{\sim}12.08mg/L,\;12.0{\sim}2,124.0mg/L,\;5.01{\sim}11.50mg/L,\;0.5{\sim}6.0mg/L$ respectively.
