Based on the assessment of water quality of Dongjiang River located in Dongguan area and the water evaluation cri- terions for environmental quality standard of surface water （Chinese National Standard GBSg38 -2002）, the composite pollution index （CPI） is calculated from the parameters of TP, BOD, NH3-N, CODcr and heavy metals （Cu, Pb. ）. The CPI values are then evalua- ted to the water quality assessment. The major pollution factors of each monitoring section include CODcr, and TP, Characterization of domestic indicating wastewater has also indicated low concentrations of metals, thereby indicating no threat of metal pollution.
