Due to overexploitation, there is the deterioration of groundwater quality and 12 hence to evaluate the groundwater quality, a study was undertaken to understand the water suitability for drinking 13 as well as for irrigation purposes. For this study, five villages namely Kumulur, Tachankurunchi, Pudurutamanur, 14 Pandaravadai, and Poovalur were selected from Trichy District, Tamil Nadu, India with an areal extent of 45.1 km2.
