Assessment of heavy metal concentrations in groundwater sources adjacent to municipal solid waste disposal site at Thirunallar, Karaikal, India

Author(s): Jeevendran S, Poyyamoli G
Abstract: This study was carried out to assess the extent of the heavy metal pollution level in the groundwater at Thirunallar temple town in the vicinity of MSW dump site at Thirunallar Municipality. Thirty groundwater samples were collected during March 2015 around the study area. Selected heavy metals and the key physico chemical parameters were analyzed by standard methods. The average concentrations of heavy metals -Cu, Zn, Mn, Pb, Cd, and Cr were 0.08, 0.37, 0.03, 0.17, 0.31, and 0.13 mg/l respectively. Correlation matrix indicates that the groundwater has assimilated various contaminants from the chemical industries, agricultural activities, and largely untreated municipal sewage systems. The concentrations of Cu, Mn, Pb, Cd, and Cr were beyond the prescribed CPCB standards (India), hence the groundwater near the vicinity of the solid waste disposal site can be used only for the irrigational and non drinking domestic purposes, while it is highly unsafe for drinking purpose.
