Abstract: | 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 and compared the results of efforts to clean-up Gombak River which passes through several industrial areas and the City of Kuala Lumpur and Penchala River which passes through the industrial areas and the neighboring City of Petaling Jaya. The trends in the levels of nitrates, chlorides and phosphates present in the rivers were analyzed. Over the period of thirteen years from 1997 to 2009, results of efforts which included public participation, engineering and 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 and the Penchala River. |
