Groundwater is the main source of domestic and industrial activities in the city of Lahore and Kasur due to meagre resources of surface water. The current study was conducted to investigate the groundwater quality for drinking purpose and to identify the hydrochemistry of groundwater using Canadian Council of Ministers for the Environment Water Quality Index and Gibb’s graph. 40 water samples were taken from different areas of Lahore city and 19 samples were collected from Kasur city. These samples were tested by 15 physiochemical parameters (pH, EC, TDS, TH, Turbidity, HCO3, Cl, Ca, K, Mg and Na) and heavy metal (Zn, Cu, Fe and As). According to water quality index model results, groundwater of Lahore city lie between excellent to the marginal category, whereas the groundwater of Kasur fall under good to poor category. Evaporation and rock water interaction influence were dominant in both of the study areas, which clearly indicates the interaction between rock and percolated water geochemistry. It is recommended that the government should install more tube wells at a considerable depth to ensure contamination free and excellent drinking water at the consumer’s end
