Summary:[...]waste water is discharged into natural water sources, lowering the quality of ground and surface water (Awan et al., 2002). According to estimates, the country's population would rise from 141 million to 221 million by 2025, while the amount of water available per person will decrease from 5,600 m3 to 1,000 m3.Unrestricted discharge of industrial and domestic wastewater into natural water bodies without proper treatment is causing a decline in water quality. According to Mohsin et al., (2013) the study conducted in satellite town area in Lahore, Pakistan shows the high concentration of calcium which was approximately around 310mg/l which were above the permissible limits as per standards of PAK-EPA, and in Islamic colony the concentration of chloride was reported above permissible limits while Sodium quantity in Shahdrah was 28-33mg/l which was also quietly lower from WHO standard limit of 200 mg/1 and could be harmful for the health of local inhabitants. The study aimed to comprehensively evaluate the physiochemical parameters encompassing pH, total dissolved solids (TDS), total solids (TS), total hardness, sulfate and chloride ions concentration, electrical conductivity (EC), additionally the research focus on determining the concentration of heavy metals in the study area. Because the proximal distance of study area is near to the industrial zone and may be the industrial effluents from the drainage point source may affect the water horizon in the different sectors of the study area.
