- KonferenzbeitragAssessing Long-term Impact of Oil Burning on the Terrestrial Environment of Kuwait(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Omar, Samira A.; Grealish, Gerard; Roy, WaleedDuring the Gulf War in 1990/91, the Kuwait desert environment was polluted by the formation of oil lakes and oil-contaminated surfaces resulting from the sabotage of the oil infrastructure by the retreating Iraqi troops. The purpose of this study was to determine the magnitude of oil damage still present almost ten years after extinguishing the oil fires, in two of the largest oil-fields in Kuwait called: the Greater Al-Burqan and AsSabriyah/Ar-Rawdatayn oil fields. The objectives of the survey were to: 1) categorize the types of damage; 2) seize the extent of damage; and 3) estimate the volume of contaminated soil. The field survey identified four types of oil-contaminated soil layers (liquid oil, oily soil, tar mat and soot) and a ‘clean’ soil type, where no oil contamination was observed. Field observation, and laboratory data (TPH, Heavy metals, EC and PH) were conducted. Mapping of each group was conducted by using GIS. A map with a scale of 1:50,000 was generated from the data, which showed the distribution of contamination. The estimated total amount of contaminated soil volume was of about 31.3 million m3. The bulk of the contaminated soil occurs in the dry oil lake map unit areas and the oil lake areas. Further work is now required to determine the risk posed by each contamination category, which is a function of the hazard and exposure to the hazard.
- KonferenzbeitragDevelopment of Monitoring and Assessment Database System (EDMRAS) for War Related Environmental Damages in Kuwait(Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Roy, Waleed; Assem, AdelOver a decade several survey and assessment projects have been conducted in Kuwait relating to assessing environmental damages due to war. Data and information has been collected characterizing the pollution in the air, water and soil in areas affected by spreading of pollution. Despite these efforts there exists a gap in knowledge on the longterm effects of the released pollutants, their fate and pathways as well as the potential risks associated with their existence in the environment. A five-year program has been developed to monitor and assess the damages resulting form the events associated with the Iraqi aggression in Kuwait. This requires compilation of all relevant data and information and their critical evaluation. In addition, intensive monitoring has been implemented to characterize in details the present quality/pollution of the different environmental compartments-ground water, marine and coastal, terrestrial and public health consequences. An integrated Environmental Data Management, Reporting and Assessment System (EDMRAS) has been developed for the program by compiling outputs from different environmental components. The system supports multiple environmental data themes such as air, soil, water, flora and fauna. The system allows collection of data from a variety of sources and projects to provide an overview of environmental conditions. Comparison of existing conditions with baseline data can be achieved allowing for rapid assessment of environmental effects. It has the ability to be integrated with a wide variety of analysis and numerical modeling software, allowing users to automate analysis and modeling processes and ensuring that all work is based upon the most reliable, up to date information available.
