Abstract
Water is a valuable resource that all life on Earth requires to survive. The increasing negative effects of pollution on the natural environment, particularly on water resources, has necessitated an assessment of water resources, particularly surface water such as rivers. As a result, the current study was carried out in the Tuirial River, Aizawl Mizoram, which is one of the most important rivers in Aizawl. Evaluating water quality before any use, such as drinking, domestic, or agricultural, is necessary for the betterment of man, society, and economic growth. Water parameters such as pH, temperature, EC, turbidity, TA, DO, BOD, chloride, and phosphate were measured at five different sampling stations over two years (2020-2021). The outcome reveals that pH and DO were lowest during the monsoon season and highest during the winter. The monsoon season saw the highest levels of water temperature, EC, turbidity, BOD, and phosphates, while total alkalinity and chloride reached their peak levels in the summer. Except for phosphate and turbidity, almost all the analyzed parameters were within the permissible limits set by various agencies. According to the studyââ¬â¢s findings, the Tuirial River has deteriorated due to anthropogenic activities such as the dumping of domestic waste and agricultural fertilizers.
