Water is important for life and most of the household usage of water is completed by the groundwater. The determination of this study is to assess the pollutions of groundwater based on the presence of different components in the groundwater. The ground water samples were collected from seventy different locations in six different cities; Multan, Vehari, Khanewal, Sahiwal, Pakpattan, and Lodhran. All the analysis of the collected water samples were performed in Pure Solution Lab. Faisalabad. Eleven parameters, pH, total hardness, calcium, magnesium, chloride, TDS, turbidity, Sulfate, Sodium, Potassium and Nitrite, were assessed to estimate the quality of groundwater. The quantity of those physicochemical parameters was assessed using multiple analytical methods. To assess the spatial distribution of those eleven parameters in six different cities of district of Multan, the Inverse Distance Weighted (IDW) technique was implemented popular ArcGIS v 10.0 software. The results showed that the on the basis of hardness, more than 50% of the region has unfit ground water. The pH assessment of these samples remained in the allowed range i.e. 6.5-8.5.The total suspended solids concentration ranged from 3661.75 to 3790.25 mg/L, which was greater than the standard value of 1000 mg/L. The nitrate focus (0.126 to 8.74 ppm) also between the WHO permissible limit (50ppm). The chloride concentration ranged between (38.04-463.413ppm), which was higher than the WHO standard value of (250ppm). Calcium concentrations ranging from 40.93 to 198.6 ppm and sodium concentrations ranging from 28.59 to 661.82 ppm were also within WHO's permissible limits (50 ppm). Overall, the results showed that most of the parameters had higher values than the standards, indicating that sewage waste water was negatively moving the quality of drinking water. IDW predicted the most contaminated region of different cities of district Multan. The results indicate that the aquifer water in all of the investigated locations is unsafe for consumption and for household applications, as the majority of the evaluated parameters defected from the WHO criteria. According to the research, drinking contaminated groundwater is dangerous, and installing water filter plants throughout all rural regions is urgently needed to satisfy with government health-related standards.
