Characterizing Urban Runoff Pollution in Malaysia: Impacts, Analysis, and Strategies

In Malaysia, rapid urbanization has exacerbated runoff pollution, leading to widespread water pollution, particularly from runoff containing various pollutants such as nutrients, heavy metals, and hydrocarbons originating from industrial, residential, and transportation sources. To address this problem, a study was conducted to characterize urban runoff pollutants in Malaysia. Primary data were collected from several potential urban spots based on different land uses in Penang, including livestock farming, agricultural, industrial, road & highway, commercial, and residential areas. The secondary data were obtained from Perbadanan Putrajaya and the Department of Irrigation & Drainage (DID) Malaysia and underwent data screening and validation based on land uses. The actual urban runoff pollutant concentrations have been studied, resulting in a whole new range of datasets that reflect the current condition in Malaysia across different land uses, such as BOD: 10.2-140 mg/L, COD: 30.5-291 mg/L, TSS: 10-298 mg/L, TN: 0.6-12.3 mg/L, TP: 0.4-21.8 mg/L, AN: 1.0-9.0 mg/L. The data obtained provide insights into pollutant concentrations across different land uses, facilitating the development of strategies such as stormwater best management practices (BMPs) for mitigating urban runoff pollution. By establishing baseline data, the research informs future efforts to manage and treat urban runoff effectively, offering valuable insights for urban planning and environmental protection initiatives.
