Concerns for the river environment in Malaysia are highlighted. There had been occurrences of inadequate supply for water in big cities and unexpected floods over the last few years. This paper discussed the results of ‘clean-up’ efforts of Gombak River which passes through several industrial areas and the City of Kuala Lumpur. The trends in the levels of nitrates, chlorides and phosphates present in the river water were observed. Water quality index was also used to assess the general water quality of the river. Over the period of nine years from 1997 to 2005, results of efforts which included public participation, engineering, river works and strict statutory regulations by government had shown success in improving the river water quality. Continued efforts from stakeholders must be harnessed to enhance the health of the Gombak River.
Key words: Chloride, nitrate, phosphate, urban river pollution, water quality index.
