Detection of Pollutants present in the surface water of Ayad River, Udaipur, Rajasthan

The present study focuses on detection of pollutants in the Ayad River flowing through Udaipur city in Rajasthan (India). Water samples from three different locations of the river were collected and analyzed over a period of three months from June 2020 to August 2020 to determine the water quality on various parameters such as Total Hardness, Total Dissolved Solids, Chloride, Sulphate, Fluoride, Iron, pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO) etc. The highest pH value recorded was 8.96, the lowest DO was 1.10 mg/l, and the highest values of COD and BOD were found to be 480.0 mg/l and 162.0 mg/l respectively. It was observed that the water at the location where the industrial effluents were discharged into the river was more polluted as compared to the other two locations with respect to most of the parameters.
