Abstract

There are 19 wards in Derabassi town of Punjab, India and the waste of these wards are dumped into a nonengineered landfill exists in Saidpura, Derabassi, Punjab, India. Leachate samples were collected from a non-engineered landfill site in Saidpura, Derabassi, Punjab, India and groundwater samples were collected from the area surrounding the landfill site, to evaluate the conceivable effects of leachate percolation impact on groundwater quality. Various physiochemical parameters’ concentrations including heavy metals like Pb, Zn, Cu and Ni were measured in leachate samples and groundwater samples. The concentrations of Chlorides, Pb, Ni, Zn, Cu etc. were observed to be in extensive levels in the groundwater samples especially those which were in the proximity of the Saidpura landfill site, likely conveying that groundwater quality is being influenced by leachate percolation. Thus the presence of contaminants in groundwater especially close to the Saidpura landfill site cautions its quality and in this way unsuitable for residential water supply and different employments. People living there should avoid using groundwater from the wells in the proximity of the landfill site of Saidpura. If unavoidable, wells’ depth should be more and frequent testing of water samples is desirable
