This study investigates the impact of industrial and urban effluents on groundwater quality in Faisalabad, Pakistan. Groundwater, a crucial resource for various essential uses, faces significant threats due to overuse and poor management, particularly from the unchecked release of industrial and household wastes. The research focuses on the contamination of groundwater by industrial and urban effluents, which are often discharged through unlined drains and agricultural practices involving chemical agents like fertilizers and pesticides. Samples were collected from different distances (50 m, 100 m, and 150 m) from drain outlets to analyze the physiochemical properties of both drain water and groundwater. The study utilized Geographic Information Systems (GIS) to map and analyze the distribution and impact of contaminants. Key parameters such as pH, electrical conductivity (EC), total dissolved solids (TDS), total hardness, bicarbonates, calcium and magnesium hardness, and chloride levels were examined. The findings indicate that contaminant levels are highest in drain water and increase with proximity to the drainage sources, except for pH levels. All samples exceeded the World Health Organization's (WHO) safe limits, posing significant public health risks. The study highlights the urgent need for improved waste management and water treatment practices to safeguard public health and ensure water security in Faisalabad. Additionally, the concentration of pollutants in drain water is correlated with key indicators such as EC, TDS, total hardness, and magnesium hardness, emphasizing their role in deteriorating aquifer water quality. Groundwater samples collected 50 meters from drains exhibited the highest pollutant concentrations compared to those taken further away.This study investigates the impact of industrial and urban effluents on groundwater quality in Faisalabad, Pakistan.
