The effect of leachate from landfill in the eutrophication of a river / Haliza Abd Aziz

An experimental study was conducted on a river beside a landfill. The purpose of the study is to investigate the effect of leachate from the landfill in the eutrophication of a river. The landfill site is at Batu 10, Jalan Bukit Kemuning, Kelang and the affected river concern is the Klang river. The importance of the study is due to the following reasons: i) Current and global issues, as river pollution and garbage disposal are environmental problems that should be given top priorities. ü) Landfill leachate has a complex characteristics which poses a threat to the environment and is a potential hazard for human health if it is not properiy control. iii) The effect of eutrophication to rivers could cause a lot of problems to the water body ecosystem and effect the vital uses of water. From the analysis results, it was found that the water samples taken from both upstream and downstream stations, contained high level of nitrates and phosphorus, which could stimulate the growth of algae. This shows that the Kelang River did experienced the eutrophication process but since the size of the river is large and the water is flowing, eutrophication did not effect it very severely.
