Assessment of Groundwater and Surface Water Quality Indices for Heavy Metals nearby Area of Parli Thermal Power Plant
Journal Title: Universal Journal of Environmental Research and Technology - Year 2012, Vol 2, Issue 1
Abstract
The increasing heaps of fly ash generated from coal based thermal power plants become a concerning environmental issue. The fly ash is burned residue of coal which has alarming dimensions, open dumping of fly ash can creates environmental problems such as contamination of surface and groundwater resources by leaching process. During present the investigation the underground and surface water samples were collected from the surrounding areas of fly ash dumping site near Parli Thermal Power Station (PTPS). The heavy metal pollution index (HPI) of the underground and surface water samples shows that, concentration of certain heavy metals is above permissible limit. The heavy metals like As, Hg and Zn shows highest concentration, while metals such as Cu, Cd and Pb shows low concentration. The HPI of ground water were found comparatively low as compare with critical pollution limit of 100. The HPI of surface water near fly ash dumping site were ranged 5.56. The heavy metal pollution index indicates that leaching of fly ash contaminates the groundwater as well as surface water.
