Water contamination is a research area that focuses on the sources, distribution, and effects of pollutants in water systems. This can include contamination from industrial processes, agriculture, urban runoff, and other human activities. Research in this area aims to understand the impact of water contamination on ecosystems and human health, develop methods for monitoring and remediation, and inform policy decisions to protect water quality. Key research topics may include the presence of heavy metals, organic compounds, pathogens, and other contaminants in water sources, as well as the development of sustainable water management strategies to prevent contamination.
