Oil spillage leaves behind residual crude oil that remained after the episode. It would
change the infiltration rate of sediment. This study compares infiltration rates for sand
before and after being stained with the residual crude oil. Material preparation started
with sieving process of sand and average size in a range from 0.355 mm to 0.71 mm.
The experiment of infiltration rate for unpolluted sand was carried out. The result
obtained stated that water depth over time taken were constant after the experiment
had been repeated for 20 times. Then, the experiment was repeated with polluted
sand and the result showed that it’s consumed more time for water to infiltrate. The
comparison between this two experiment shows that the infiltration rate was
decreasing. This is because crude oil in soils trapped some of the water, consequently
lowering the coefficient of permeability of polluted soils.
