Water quality study at Skudai River, 2002 – 2006

Assessing the level of river water quality periodically is important in ensuring that the river water is safe for consumption. This study investigates the level of water quality at Skudai River from year 2002 to 2006. Twenty parameters were identified and used in this analysis. These twenty parameters are recorded at nine monitoring stations located along the Skudai River. Multivariate statistical techniques i.e. factor and cluster analysis were used in this analysis. From this analysis we managed to group the monitoring stations into three categories: seriously polluted, moderately polluted and clean.
