At present, Pakistan is striving hard to uplift its economy with sustainability. Agriculture, being the largest economic support system of the country, also faces numerous challenges due to changes in socio-environmental practices. This research has been performed to evaluate and map the quality of groundwater resource as per United Nations Sustainable Development Goals (UNSDG 6). Water samples of 125 wells were taken from the Punjab irrigation department, for pre and post monsoon 2010 and 2018, respectively. TDS, EC, SAR and RSC were selected as physiochemical parameters for groundwater of Lahore, Kasur and Okara. Data was processed in ArcGIS environment to produce interpolated maps. Regression analysis was performed to determine the degree of impacts by combination of two parameters. In 2010, TDS values were found dispersed after rainfall and slight hazard for salinity was observed. In 2018, TDS values were found high in Kasur. SAR values showed increase after rainfall and severity of RSC shifted from 14 to 17 wells in post-monsoon. Rise in concentration of residual sodium carbonates after rainfall indicates that deposition of minerals amplified with less retention time and undulating slope throughout the region of Bari Doab. It is recommended to restrict the exploitation of groundwater with incorporation of efficient water governance at district levels.
