Assessment and Behaviour of Landfill Gas Emission in Jleeb AI-Sheyoukh Landfill Site in Kuwait
Kuwait has witnessed a significant increase in urbanization,industrialization and development activities during the last four decades.As a result,most of the 18 landfill sites in the country became very close to residential,commercial and industrial areas.Currently,4 landfills are still operating in Kuwait and the rest of the 18 landfills are closed.Most of landfill sites in Kuwait are surrounded with significant proportions of human settlements,hence imposing potential threats to human health and the environment.The emission of LFG and the formation of leachate are of major concerns to local communities because of the bad smell and offensive odour as well as due to the various potential health and environmental hazards associated with toxic organic and inorganic compounds present in LFG and in LF leachate.Jleeb Al-Sheyoukh landfill (JLF) was chosen for conducting this study being the largest landfill site in Kuwait (with an estimated area of 5.5 km2),located at a distance of less than 1 km from both residential areas and Kuwait International Airport,and hence is considered to be a potential health and environmental hazards to its surroundings.LFG composition and emission behaviour was monitored in 32 boreholes in Jleeb A1-Sheyoukh landfill (JLF) site for a period of 33 months during 2008-2010.The monthly averages of LFG measurements performed over a period of 33 months showed an average content of methane about 30% and an average content of carbon dioxide about 26%,while the oxygen levels were negligible and the mean ratio of CH4/CO2 was about 1.14.This indicates that JLF stands at the end of the Air Infiltration Phase.During this period of time,no noticeable change in the methane gas production has been detected which indicates that the decay process is almost stable and hence the life time of the landfill might be extended.Therefore,in-situ or ex-situ rehabilitation methods are necessary for the treatment of buffed wastes before the reclamation of JLF site.
