A study was conducted to assess the water quality status of Engineering and Serumpun
Lakes located in campus area. Selected water quality parameters (Biochemical Oxygen Demand -
BOD, Chemical Oxygen Demand-COD, Dissolved Oxygen-DO, turbidity, Suspended Solids-SS,
pH and Ammonia Nitrogen-NH3-N) were determined for about two months observation in the
wet season and the average results were compared to Malaysian standards. The status of lakes
were determined by using Water Quality Index (WQI) and classified according to the Interim
National Water Quality Standards (INWQS), Malaysia. The observed values for seven
parameters of Engineering Lake were classified as IIA/B and V classes as well as Serumpun
Lake. From the results, the lakes can be used for recreational purposes. However, based on WQI
calculated value, the status of the lakes during the study period was indicated as polluted; 31.6
and 32.5 for Engineering and Serumpun lakes, respectively. Both lakes were classified as Class
IV and the water suitable for irrigation uses only.
