HIGHLIGHTS

  • Eight water quality parameters of Serumpun lake were analyzed.
  • The lake was classified as polluted based on WQI classification.
  • The output of the surface water interpolation of eight parameters was illustrated in GIS based maps.
  • Geospatial analysis using IDW spatial tool evaluated the contribution of each parameter.

ABSTRACT

Geospatial analysis of eight water quality parameters was applied for the assessment of the water quality of Serumpun lake located in Universiti Putra Malaysia (UPM), Selangor. The Interim Water Quality Standard Malaysia (INWQS), Malaysian water quality index (WQI) and the Canadian water quality standards were applied for classification of the lake water. The spatial distribution of the water quality parameters was achieved by interpolation using inverse distance weighting (IDW) method. The result of the investigation indicated that the lake was polluted according to the Malaysian WQI having a value of 22.4. The three sub-index parameters were also classified as polluted according to the Department of Environment (DOE), Malaysia. The Canadian Council of Ministers of the Environment Water Quality Index (CCME-WQI) was used for further classification of the lake. The result of CCME-WQI showed that the lake was polluted with a value of 25.91.
