Abstract
This paper presents a case study on surface water quality assessment at Merbok river, Kuala Muda, Kedah. The study provides an insight on the feasibility of environmental pollution monitoring through in-situ water quality measurement. The study was conducted in the span of five months from November 2020 to March 2021 where the water quality samples were taken twice daily using water quality system and turbidity probes of EUTECH CyberScan PCD650 and EUTECH-TN100 respectively. The measured water quality parameters are pH, dissolved oxygen, conductivity, total dissolved solids, salinity, resistivity, and turbidity. Results from the sampling analysis have shown that water quality parameters of Merbok River are categorized as Class III according to the National Water Quality Standards (NWQS). The study identified a spike in pH (8.9) and dissolved oxygen in February possibly caused from dumping of industrial waste. Turbidity shows an increase during monsoon season followed by an increase in conductivity, resistivity and salinity in the dry season which implies surface runoff from industrial discharges. The state of Merbok River requires necessary attention from authorities and policy makers, to prevent future contamination that degrades the diverse ecosystem. © 2022, Springer Nature Switzerland AG.
