Abstract: Kelana Jaya lakes are public attraction for its recreational value.
However, urban runoff and industrial wastes into these urban lakes could
contaminate the environmental quality of the lakes. In this study, water
samples from the five lakes of Kelana Jaya were monitored for temperature, pH,
conductivity, dissolved oxygen, ammonia, nitrate, phosphate and dissolved
concentrations of Cd, Cu and Zn, at four different sampling periods on 5 May, 5
June, 13 Oct and 1 Nov 2003. These physico-chemical parameters indicated that
Lakes 1, 2, 4 and 5 were classified under 'Class III'
(slightly polluted, recreational use, need treatment) while only Lake 3 was
under 'Class II' (clean, recreational use with body
contact) according to Malaysian DOE water quality classification (2002).
Therefore, the overall poor water quality of Kelana Jaya Lakes indicated
anthropogenic impact and future water quality monitoring and control of the
wastes into the lakes are strongly recommended.
