Assessment of Kuwait's Al-Qurain Landfill Using Remotely Sensed Data

Kuwait's Al-Qurain landfill problem resulted from indiscriminate dumping of domestic and industrial waste in an abandoned quarry in the late 1970s and early 1980s. The landfill and surrounding areas were set aside for a government housing project without an environmental assessment of the impact of the landfill on the project. Inhabitants of the newly constructed housing area experienced persistent foul odor emanating from the landfill site. Since then, the issue has generated a lot of public interests, and several remediation measures have been adopted. In this preliminary study, several remotely sensed data consisting of Landsat Multispectral Scanner (MSS), Landsat Thematic Mapper (TM), IKONOS, and synthetic aperture radar (SAR) acquired between 1972 and 2000 were processed and assessed for their usefulness to study and monitor the landfill site. The imagery provided a historical perspective of how the areas had changed over the last 30 years. Other useful information of the landfill obtained from the satellite imagery included the spatial extent, spectral reflectance, surface temperature, and surface roughness. The landfill site showed higher surface temperatures compared to the immediate surrounding areas-a process that could accelerate the biodegradation and the release of landfill gases. Such dataset could be incorporated into a GIS for the long-term monitoring of the site.
