Amarkantak Thermal electricity plants utilize bituminous coal as a fuel, which incorporates an excessive amount of ash (as much as 40 %), sulfur (0.2- 06%), and heavy metals such as Hg, Mn, Cu, Pb, Ni, Fe, Cr and Cd in varying percentage. However fly ash generally includes just about 50% silica which together with oxides of Al, Fe, and Ca increases 95 to 99 percent of its contents whereas Na, Mg, Ti, K, C, and S make up 0.5 - 3.5%. The rest of the ash comprises trace elements. (Davison et al., 1974). The plant disposed of ash combined with warm wastewater at the Sone River and for that reason, it has an unfavorable effect on the river. Consequently, the quality of the water has been altered. Some studies have confirmed that a big quantity of heavy metals, like lead, copper, nickel, silicon, etc were found in the disposal water. Water quality in any ecosystem provides significant information about the resources accessible to support life in that ecosystem. Several physicals, chemical and biological parameters of water indicate the quality of water bodies that can vary under the toxic effects of pollutants. In the present observation, in water, the concentration of metals such as Pb, Al, Fe, and Cr was found much higher than the permissible limits prescribed by WHO and Indian Standards.
