| dc.description.abstract | Soil contamination by diesel oil normally occurs due to spillage from vehicles, accidental discharge from tanker, or leaks in pipes. This type of contamination causes significant destruction to the environment. The hydrocarbon of the diesel oil continuously impacts the quality and physical characteristics of soil. In regard to these concerns, the main aim of this research has been to study the effects of introducing a volume of the Light Non Aqueous Phase Liquid (LNAPL) into a body of poorly graded sand with the water table fluctuated. The behaviour of LNAPL migration was observed and described. The one dimensional column test and Simplified Image Analysis Method (SIAM) were employed. The first case involved a water table that was first lowered and then raised. In this case, the amounts of diesel oil that was entrapped in the saturated soil were 9 % when 50 ml of diesel oil was used and 4 % when 25 ml of diesel oil was used. The second case involved a water table that was first raised and then lowered. In this case, the amounts of diesel oil that was entrapped in the unsaturated soil were 10 % when 50 ml of the diesel oil was used and 3 % when 25 ml of diesel oil was used. Among the given circumstances and possibilities, the most critical was when the water table was lowered and then raised, with 50 ml of diesel oil used. | en_US |
