| Summary: | Danau Kota Lake is public attraction area, located in the middle area of Kuala Lumpur. An excessive count of visitors
visiting the lake has weakening the lake water quality. The present study was driven to evaluate the lake water quality
for environmental conservation. Some water quality and metals data were in-situ measured whereas some were
collected for laboratory analysis. BOD, OG, AN and TC are identified as major pollutants towards Danau Kota Lake
water quality. The decreasing concentration of DO and increasing of turbidity towards the deeper lake water column
has been deteriorated the living water communities and caused hypoxic condition in the bottom water of Danau Kota
Lake. Spatial variation of metals in the lake sediment has evidenced the accumulation of metals in the middle part of
the lake area due to the sedimentation process. Based on PCA, the possible pollutant sources for this lake are the
organic pollutants from the wastewater and industrial pollutants as well as the abundance of suspended algae. Since
the water quality of Danau Kota Lake has marked some issues, the present study may assist Kuala Lumpur City
Council to prevail the lake water quality challenge promptly by cost saving and in efficient manner |
