The current study was carried out over a one-year period (October 2019 to September 2020) where the samples were taken at monthly intervals to determine the impact of human activities on water quality. The research area was divided into four sampling locations along the river, from upstream to downstream. Municipal waste, biomedical effluents, untreated city garbage, domestic and sewage discharges from the catchment area are received at Sites 1 and 2; the downstream Sites 3 and 4 are typical tourist attractions that eventually join the Tlawng river. For the study of Tuikual river water quality, important parameters such as pH, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Total Dissolved Solids (TDS), Total Hardness (TH), Nitrate-N and Phosphate-P were estimated. The results were then compared to water quality standards set by the United States of Public Health (USPH), Bureau of Indian Standards (BIS) and World Health Organization (WHO). The results indicate that systematic correlation coefficient calculation and regression analysis proved to be a practical method for quick monitoring the water quality of the Tuikual river. The results show that unplanned and direct waste discharge from various sources has significantly deteriorated water quality at all study sites. This investigation could lead to more in-depth studies of the Tuikual river's water resources, as well as the development of water management policies and activities.
