Statistical comparison of pH, COD and NH3-N in-situ physico-chemical parameter in relation to surface water pollution status at Terengganu and Kinta River Basins, Malaysia

Abstract
Statistical comparison has been performed for Terengganu and Kinta River Basins in terms of surface water pollution status using some selected physico-chemical parameters. Surface water quality data were collected from Department of Environment (DOE) Malaysia and subjected to logarithm transformation (log-scaling), column auto scaling and z-standardization to eliminate the effects of measurement units. Results revealed that pH value is higher in Terengganu River Basin compared to Kinta River Basin. Two-way analysis of variance (2-way ANOVA) showed spatial and temporal statistical significant differences (p
