Pollution

Heavy metals on fly ash surface has tendency to leach and contaminate the ground water, which will affect the human by entering food chain. Present study has been carried out to assess the ground water contamination in the surrounding villages closer to two thermal power plants in Delhi, India. Ground water samples from different location within the 2 Km radius of both thermal power plants were collected and analyzed for heavy metals (Cd, Cr, Cu, Fe, Ni and Pb). This study indicates that the bore well and pond water within the study area is contaminated with higher concentration level of these heavy metals. The concentrations of these selected heavy metals are crossing the prescribed standard of drinking water quality in India. Supernatant of ash ponds contain heavy metals, needs remediation before discharging into the environment.
