Tuipui River is the main source of potable water in Champhai district of Mizoram. With the growth of population and developmental activities, there is a high risk of pollution especially with regards to the surface water bodies. The present study has been carried out for a period of two successive years i.e. from February 2018 to January 2019 and from February 2019 to January 2020, to assess the quality of river water (untreated) and PHED treated water and to determine the pollutant removal efficiency of the water treatment unit. The water samples were analyzed for selected physical characteristics namely temperature, turbidity, and total dissolved solids on monthly intervals, and results have been presented on a seasonal basis. The findings reveal that the average temperature ranges from 16.95℃ to 24.59℃ for untreated river water and 18℃ to 24.62℃ for PHED treated water. Similarly, turbidity ranges from 2.1 NTU to 34.89 NTU for untreated water and 0.6 NTU to 11.87 NTU for treated water, and total dissolved solids (TDS) ranges from 29.48 mg/L to 45.37 mg/L for untreated water and 28.78 mg/L to 43.45 mg/L for treated water. The findings were also compared with the standards given by scientific agencies. The sharp increase in turbidity during the monsoon season could be attributed due to rain and indicating the inefficiency of the treatment plant to minimize the values at the desired pace.
