Water quality research focuses on studying the physical, chemical, and biological characteristics of water to assess its suitability for different uses, such as drinking, agriculture, industry, and recreation. This research includes monitoring and assessing water pollution levels, identifying sources of contamination, developing strategies for water quality management and protection, and implementing measures to improve water quality. Researchers in this area utilize various methods and techniques, such as sampling, analysis, modeling, and remote sensing, to understand the factors affecting water quality and to promote sustainable water management practices. Ultimately, the goal of water quality research is to ensure safe and clean water resources for human and ecosystem health.
