Abstract:

The issue of leakage and spillage of light non-aqueous phase liquids (LNAPLs) and aqueous phase liquids (APLs) contribute to groundwater contamination, resulting in groundwater pollution and rendering the quality of groundwater unsafe for drinking and agricultural use. This paper aimed to investigate the APL and LNAPL in the deformable double-porosity soil, which has become important for sustainability of groundwater utilization and a comprehensive understanding of the characteristics of APL and LNAPL migration into the groundwater through the use of digital image processing techniques. The results of the experiments show that the flow of the APL and LNAPL migration was not uniformly downward. Faster migration occurred at the cracked soil surface condition compared to other locations on the soil surface that were not cracked, even when not using a liquid such as toluene. It was concluded that the factors that significantly influenced the APL and LNAPL migration was the soil sample structure, soil sample fracture pattern, physical interaction bonding between the liquid and soil sample, and capillary pressure of the fluid. The output of this study indicates that digital image analysis can provide detailed information to enable researchers to have better understanding and simulating the pattern of liquids migration characteristics that influence the groundwater resources.
