A STUDY ON TRADITIONAL WATER QUALITY ASSESSMENT METHODS

Abstract

Water quality has been damaged in countries that have an abundance of water resources, but also by the rapid industrialization, urbanisation, and population increase. They often have significant pollution levels in the rivers. Industrial regions, sewage, agriculture, and animal husbandry are the three most prevalent anthropogenic activities. Water pollution can also result from natural calamities like floods and the illegal disposal of chemical waste. Water pollution is dangerous to human’s health, as well as the environment, society, economy, and wildlife. Hence, water quality examination is crucial for reducing challenges associated or caused by water pollution. This study delved into the review of different traditional water quality examination methods with a view to identify the most advantageous one. The traditional water quality examination methods are single-factor examination method, nemerow pollution index, comprehensive pollution index method, principle component analysis, fuzzy comprehensive evaluation method, and water quality identification index. The merits and demerites of all these methods were examined, and it was discovered that water quality identification index will be more plausible; however, it is costly.
