The study examined the comparative analysis of Chambal River water and ground water samples in Kota, India around Kota super thermal power plant. Surface and ground water samples at judicially chosen from sampling sites had been analyzed at specific intervals of time for a period of twelve months. The following parameters were determined; pH, electrical conductivity, and heavy metals such as iron, lead, chromium, arsenic, manganese, and zinc. In Kota super thermal power plant, Coal burning can emit trace elements to the surrounding environment, which could further contaminates surface water and ground water. The concentration and availability of metals depends on the character and nature of the coal used in thermal power plant. All selected metals were found above detectable limits. Cr, Mn, Fe, Arsenic, Zinc and Pb were found in greatest extent in ground water samples, i.e. Cr- 0.06 to 132 ppb, Mn 52 to 287 ppb, Fe 11 to 1571 ppb , As -0.69 to 2.83 ppb, Zn -21 to 1651 ppb, Pb-0.16 to 4.43 ppb respectively. The pH value and electrical conductivity are also examined as pH-5.5 to 7.3, E.C-323 to 556 μS/ cm in ground water samples. In the study of River water sampling the concentration of following metals werepresented as follows As, Cr, Fe, Pb, Mn, and Zn were identified concentrations, 2.0 to 4.5 ppb, 0.07 to 1.58 ppb, 6 to 76 ppb, 0.15 to 0.76 ppb, 0.4 to 3.9 ppb, 10 to 26 ppb, respectively. The pH and Electrical conductivity were observed as 7.4 to 8.1 and 280 to 357 μS/ cm in Chambal river samples. All the results were not exceeding the permissible limits as per IS.
