This study aims to determine the level of wastewater pollution at Clan Jetty, Penang. 20 locations were chosen for water sampling around the jetties. Experiments were conducted to investigate the parameters, namely, temperature at each point, Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), pH, Dissolved Oxygen (DO), the presence of Coliform and E. coli, Nitrate Nitrogen, Ammonical Nitrogen, Suspended Solids, Oil and Grease as well as Total Phosphorus (TP). Laboratory results showed that Point 1A was the most polluted location compared to other sampling points. The highest COD recording was 5824 mg/L at Point 1A and the lowest amount of 103 mg/L was recorded at Point 4. This study demonstrates that the absence of a sewerage system contributes to marine pollution around the jetties. Thus, a sewerage system is the best solution to improve water quality around the jetties in the future.
