Abstract:

The paper reports the results of a laboratory investigation aimed at evaluating the effectiveness of age of landfill and the degree of stabilization effects on the composition and characteristics of leachates of three different landfills at ages of 10, 20 and 23 years. Landfill leachates at Qurain, Sulaibiya and Jaleeb Al Shoukh solid waste disposal sites were studied by periodically collecting samples through boreholes installed at these sites. The analysis of samples showed high values in all the parameters, however, the levels of heavy metals were low. The presence of heavy metals such as As, Ca, Cd, Co, Cu, Fe, Hg, Mg, Mn, Mo, Na, Ni, Pb, Se, Sn, V and Zn was attributed to the type of solid waste materials dumped at these sites. Leachate values of Cu, Ni and V were high indicating the disposal of predominantly petroleum-related waste at the sites. Yet, the results suggest that a monitoring system such as monitoring wells could be established and treatment facilities should be built to avoid surface and groundwater contamination. Geophysical studies could be conducted to know more about the path of groundwater flow from these landfill sites to the surrounding areas in order to implement effective control systems in the future.
