ABSTRACT
In the modern time, rapid industrial growth and urban sprawl has created more demand for electricity which has created a situation of more coal-based energy stations. But, for instalment of a sustainable and stable, thermal power generation system, it is necessary to evaluate environment impact pre- and postinstalment of these projects. The present study focused on physico-chemical analysis of groundwater near Kota Thermal Power Plant, Kota, Rajasthan (India). Various physico-chemical parameters like pH, electrical conductivity, total dissolved solid, salinity, total hardness, total alkalinity, bicarbonate, calcium, magnesium, sodium, potassium, chloride, sulphate, phosphate and bromide were analyzed in 30 water samples. Heavy metals like Fe, As, Zn, Cu, Mn, Co, As, Pb, Ni and U were also analyzed using standard methodology. It was inferred that most of the water parameters fell within permissible limits prescribed by BIS except few. TDS, F, Cl, SO4 in few water samples were found above prescribed limits. Ca and Mg values were found above the permissible limit of 75 and 30 mg/l as prescribed by WHO. Uranium concentration varied from 1.23-27.57 ppb in all the groundwater samples which is also within acceptable limit.
Key words : Groundwater, heavy metals, uranium, thermal power plant
