To theses endeavor, ten soil samples were collected from the selected locations and then the relevant elements of Al, Fe, Mn, Cr, Cu, Pb, Zn, Ni, Cd, As, Co, Sb, Sc and Hg were measured and monitored using standard method. To estimate the contamination situation of soil, contamination factor (CF), enrichment factor (EF)  and  geo-accumulation  index  (Igeo)  and  potential  ecological  risk  index  (PERI)  were  computed  using geological background values. In addition, for assessing soil quality, Pearson's correlation coefficients analysis was also performed. Furthermore, this study revealed that the values of CF and Igeo in soils around the waste disposal area affected from the contamination of heavy metals mostly by Pb, Cd and Sb. In contrast, Pearson's correlation indicated that the sources of metals are almost the same and these heavy metals might be derived from the waste accumulation activity. Dump sites have great potential for energy extraction if the high valued compounds to be extracted.}, keywords = {Soil quality,heavy metals,Waste landfill,Geo-Accumulation Index,Enrichment Factor}, url = {https://www.ijee.net/article_64670.html}, eprint = {https://www.ijee.net/article_64670_f4f18fe868697cbf6ca706c00b5b5212.pdf} }
