ABSTRACT
One of the main pathways of groundwater contamination is the migration of contaminants from the soil via water flow. This usually happens due to the existing groundwater flow, rainfall, and human activities. Ground lithology, soil texture, soil type, and soil condition are the major factors affecting the contamination migration and causing contaminants to distribute evenly or over decades. The perfluoroalkyl acids concentration in samples from both groundwater and soil was reduced with the total Per- and Poly-Fluoroalkyl Substances (PFAS) concentration between 21% and 79% in the monitoring well. For in situ chemical oxidation, oxidant agents can be applied at one side of the contaminated land, and groundwater can be extracted from the other side. Maximum attempt is needed to gather the applied solvent from the groundwater not to contaminate the site additionally. For instance, precise monitoring is required through different bore holes to check and control any increase in the PFAS contaminant in the soil mass and groundwater.
