Water is vital for all living beings and is crucial for sustaining human civilization, ecosystems, and food security. Groundwater, constituting 30% of the world's freshwater, serves as a primary drinking water source. However, rapid industrialization has led to groundwater pollution, caused by various hazardous chemicals discharged by industries. To assess the quality of groundwater in Faisalabad district's industrial zone, a study collected samples from 40 locations and used physiochemical analysis and IDW interpolation techniques to create groundwater quality maps, revealing minimum and maximum values of pH (7.175 to 8.899 mg/l), TDS (182.90-444.5 mg/l), sulphate (80.08-449.77 mg/l), nitrite (0.00004-2.998 mg/l), chloride (5.439-388.55 mg/l), calcium (10.125-347.24 mg/l), sodium (7.254-1378.8 mg/l), potassium (3.126-44.156 mg/l), Total hardness (80.05-983.77 mg/l) in Faisalabad. Researchers employed GIS (Geographic Information System) to analyze the spatial distribution of various physico-chemical parameters. The study utilized ARC GIS 10 software to create spatial variation maps. The investigation focused on groundwater quality mapping in Faisalabad, aiming to identify suitable water sources for agriculture and drinking. Unfortunately, the findings indicated unfavorable groundwater conditions for these purposes. To make the water safe for human consumption and control pollution, improvements in treating industrial and sewage effluents are necessary.
