Abstract Several studies have been conducted in Kuwait by local and international organizations to understand the nature and extent of the damage made by the oil lakes to the environment and ecosystem. The including results of the present study clearly indicate that the problems persist even after 25 years. In fact, although the lakes and lagoons that contained oil have been drained and many of them have dried out, their hazard potential has actually increased. The present study was performed by testing grids at different locations within the contaminated areas and a reference non-contaminated areas (GC32 PL, Burgan field). Visual inspection, topography surveys through groundtruthing activities were carried out. Soil investigations include soil samples were collected from different depths using the hand tools, to profile the existing oil contamination and identify layers classification. As well as laboratory chemical analysis were conducted on the collected soil samples after compositing it to quantify the total petroleum hydrocarbon (TPH) which represent the level of contamination, particle size distributions and moisture content. The investigation of soil samples were carried out at different 60 trial test pits from different depths up to the appearance of a clean soil. The study in dry oil lake ( zone 12 ) and wet oil lake (zone 13) indicated the presence of heavily contaminated soil (Layer 1) up to a range depth of 0.10 m to 0.90 m, underlined by the presence of dark brown colored soil (Layer 2) at depths ranged from 0.20 m to 1.5 m with slight oil odor, then the soil became pale brown and did not have any petroleum odor (clean soil) which represented as Layer 3 . |
