There is an urgency to establish an early warning system in Malaysia to predict contamination in water quality (toxic pollution at Sungai Kim Kim in Johor). • Continuous water-quality monitoring is key to establish an early warning system so remedial actions can be taken effectively by government, industries, and local communities. • Electrochemical sensor technology could be used for continuous monitoring (low cost of the fabrication process, sample to operate and scalable) PEDOT:PSS are not without any limitations; the presence of PSS acting as a dopant to stabilize PEDOT:PSS results in PEDOT:PSS being highly hydrophilic and having an appreciable degree of water solubility which in turn leads to PEDOT:PSS film degeneration and peeling off easily from the surface of electrodes, while at the same time affecting its use in aqueous media for continuous monitoring.
