Abstract

Thermal energy is the major source of power generation in India. The Power Plant
is an electricity-generating facility. Water is one of the key input requirements for
thermal power generation. Water quality impacts include temperature, dissolved
oxygen, nutrient concentrations, and redox-sensitive metals. Seasonal variations in
reservoir water quality also impact downstream conditions. The present study aims
to Impact of thermal power plants on the water quality of surface and groundwater.
Three MCDM methods AHP, MAUT and OPA have been applied to achieve the
present objective. Ten parameters such as Dissolved Oxygen (DO), Biochemical
Oxygen Demand (BOD), Electrical Conductivity (EC), Total Dissolve Solid (TDS),
Hardness, Chloride, Turbidity, Total Suspended Solid (TSS), Potential of
Hydrogen(pH) and temperature have been chosen among the various parameters based
on literature review and expert opinion to determine which one will carry the most
weight as per the MCDM methods. Here after doing the AHP, MAUT & OPA MCDM method BOD is the least and DO is the most significant parameter. Increasing WQI value the quality of water will decrease. According to the result minor effect has happened nearest point from the power plant surface and groundwater is more affected from the farthest point surface and groundwater.
