Abstract:

Leachate, soil and groundwater samples were collected from the zindana, Alwasit (1) and Alwasit (2) landfill sites in Kirkuk city (North- Iraq), to study the possible impact of leachate percolation on soil and groundwater quality. Various physicochemical parameters and heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Fe and Zn)were determined in leachate, soil and water samples to asses metal contamination due to landfill wastes. Soil contamination is assessed on the basis of Enrichment Factor, Contamination Factor and Pollution Load Index were estimated for some selected potentially hazardous elements (Zn, Pb, Cd, Sr, Ni, Mn, Cr). The results for EF values were within moderate enrichment category due to anthropogenic activity and for CF was low to moderate degree of contamination. The result of (PLI) of the three landfill sites of soil samples indicates that the soil at Kirkuk landfill sites is under load of pollution due to contaminants arising from landfill leachates. A human health risk assessment model adopted by the USEPA demonstrated for the soil and groundwater samples for the three main pathways that Human beings may expose to metals, Non-carcinogenic health effects (HQs) and the cumulative hazard quotient index (HI) for both children and adults were calculated for Mn, Ni, Pb, Sr, Zn, and Cd suggesting no health hazards for now, yet the influence of leachates may cause serious toxic risk to the soil and groundwater quality in the distant future.
