Groundwater quality in the Shivganga river basin, Western India, was evaluated by an integrated approach using pollution index of groundwater (PIG), health risk assessment (HRA) and chemometric analysis. Sixty eight (68) representative groundwater samples were collected and analysed for pH, Electrical conductivity (EC), Total dissolved solids (TDS), major cation and anion during pre- (PRM) and post (POM)-monsoon seasons of 2016. Hydro-chemical analysis inferred that EC, total hardiness, alkalinity, boron and fluoride are exceeding the permissible limits of the World Health Organisation (WHO). PIG was computed based on considered physicochemical parameters and WHO drinking standards to ascertain the degree of pollution level. PIG results inferred that about 6% samples fall in moderate, 12% in low and 82% in insignificant pollution in PRM season; while, 12% of sample fall within low, 88 …
