Abstract

An attempt has been made to assess the water quality of the DanubeRiver using water quality index technique. In this study, the Canadian Councilof Ministers of the Environment Water Quality Index (CCME-WQI) wasselected to express the quality of water for drinking water abstraction and toprovide information on the spatial and temporal variations of the river waterquality. Water quality of 13 parameters has been considered in four samplingstations during 1-year period. The European Community (EC) standards fordrinking water abstraction were used for CCME WQI calculation. The waterquality variables included in the index are dissolved oxygen, biochemicaloxygen demand, ammonium, nitrates, total phosphorus, water temperature, pH,total suspended solids, cadmium, copper, chromium, nickel and lead. Theresults revealed that the water quality was found fair in all sampling stationsexcept one station, which was marginal. It was observed that the mostimportant variables that affected the water quality were ammonium, totalphosphorous, water temperature and total suspended solids. Moreover, nosignificant changes were observed for temporal variation in the Danube riverwater quality. The CCME WQI gave reasonable results and introducedrepresentative outcomes of the raw data of the river
