Throughout the world, the lock-down period during COVID-19 (March 2020- July 2021) has reportedan improvement in the ecological scenario with controlled anthropogenic activities. This study presentsa comparative assessment of water quality of the highly polluted Khari river in Agra district (India)during the pre-pandemic and post-pandemic period of COVID-19. The result was analyzed in terms ofwater quality index (WQI), the most accessed tool used by various researchers to report the waterquality. In addition, Aggressive index (AI) and Langelier saturation index (LSI) have also beendetermined. Further, multivariate analysis has been performed in terms of principal component analysis(PCA). ANOVA has been used to study the variance of the parameters. The study revealed a positiveimpact of pandemic on the water quality as the parameters improved during the post-pandemic periodas compared to the pre-pandemic period. However, as the river was highly polluted during thepre-pandemic period, strict actions are required for further improvement in its water quality foragricultural, industrial and industrial use.
