According to Singh et al. (2018), in India, there are more than 200 power plants (116 coal‐based, 65 gas‐based, and 19 diesel‐based). The discharge of hot water from these power plants causes subsequent changes in the DO level. Other pollutants released from thermal power plants are coal dust, fly ash, and chlorinated water, and contamination of water due to heavy metals like Hg, Bi, As, and Cr are the main constituents (Sonwane 2015).
