Sabarmati is one of the largest rivers in Gujarat and passes through cities like Gandhinagar and Ahmedabad. The municipal pollutants in the river comprise untreated domestic and sewage wastes. In contrast, industrial pollutants constitute the discharge of heavy metals into the river, responsible for increasing metal load in the water. Increasing heavy metal concentration in the water can cause severe problems. In this work, Cu, Mn, Fe, Cr, Zn, Pb, and Cd heavy metals were analyzed from the five selected sites for two years, 2020 and 2021, in Two seasons pre and post-monsoon. In 2020, there was a lockdown situation because of Covid-19, so all industrial the activities were shut down. Therefore pollution levels were decreased, and the environment was clean. Our study indicates that in the pre-monsoon season in 2020, Iron metal was highest, and in post-monsoon, Chromium was the highest. In the Post-monsoon season 2020, Iron metal was the highest, and Lead was the highest in the post-monsoon season. Because of the covid-19 lockdown, the result of post-monsoon 2020 shows the low concentration of heavy metals.
