Abstract

The Perungudi dumping yard which is being used for more than 28 years as municipal waste dumping site, beyond the lifetime of 20 years for any landfill, remains the major contributor for heavy metal pollution of groundwater in and around Pallikaranai, due to the leaching activity. The current study aims at assessing the ecological condition of the wetland. The objective is achieved by assessing the heavy metal concentration (Cd, Cr, Cu, Pb) in twelve ground water samples collected from four different sites. Of these four heavy metals Pb was found in all the water samples, whereas Cr was found in eight of the twelve ground water samples. Cd and Cu was found below detectable levels to be the highest and Cadmium (Cd) to be the least accumulated in the study area.
