A comprehensive groundwater heavy metal contamination in groundwater study was conducted in Batlagundu, Dindigul District, Tamilnadu aiming to investigate the impacts of urbanization on the aqueous distributions of these elements. Groundwater samples were collected in highly urbanized spaces in the area and analyzed for heavy metals such as Zn, Cu, Pb, Cd and Fe. The results were compared with BIS and WHO standards. The concentrations of Zn were within the desirable limit at all the sampling sites. Other metals such as Fe, Cd, Cu and Pb exceed the limits. It is a well-known fact that the heavy metal ions are potentially toxic to human health and could be quite detrimental for human life. Pearson correlation analysis showed that the mean concentrations of heavy metals in the groundwater samples were positively correlated with each other. This study keep scores the value of multivariate statistical analysis for evaluation and interpretation of the data with a view to stimulate better policy outcomes and decision-making that positively impact water quality and thus prospectively diminishes the pollution caused by hazardous toxic elements in environment. Correlation coefficient between the heavy metals was calculated with a help of a programming tool SAP-ABAP.
