ASSESSMENT OF HEAVY METAL POLLUTION INDEX OF GROUNDWATER IN ARANI TALUK OF TAMILNADU, SOUTH INDIAP. Mohana, P.M. Velmurugan and M. JayaprakashAbstract The groundwater suitability is based on hydrogeochemical features water quality based on the seasonal variations were determined. Groundwater samples were collected in the Arani Taluk of Tamil Nadu, South India, and trace metals were determined to characterize and evaluate water quality. Trace metals such as Zn, Pb, Mn, Ni, Co, Fe, Cu, Cr were analyzed for the premonsoon and postmonsoon seasons. Using a GIS spatial distribution map was prepared. The spatial distribution map of water quality studies concerning trace metals shows that the water has a higher concentration of heavy metals and the results of Heavy metal pollution index (HPI) also substantiates the fact and many groundwater samples were found to show higher values than the allowed limit concerning heavy metal contamination. |
