Assessment of water quality using water quality index: A case study of the River Gomti, Lucknow, Uttar Pradesh, India

ABSTRACT

Considering the heavy pollution load due to natural and anthropogenic activities, the Gomti River has been chosen to conduct this study. A total of eight parameters (pH, EC, TDS, TH, Chloride, DO, BOD, and Alkalinity) have been selected to assess the water quality. These parameters were measured at seven sampling stations (S1 to S7) for the years 2013 to 2017 in Lucknow city. The Weighted Arithmetic Index method was used to calculate the water quality index. The results of the study revealed that all of the water samples fall under the different categories of poor (50 to 75), very poor (75 to 100), and unsuitable (>100). During 2017, the recorded values of WQI were found in the range of 71.11 (minimum at S1) to 165.33 (maximum at S7), whereas in 2013 these were observed in the range of 67.90 (minimum at S1) to 143.63 (maximum at S7).
