Abstract

Groundwater pollution caused by oil spill accidents has been reported occasionally, and the groundwater remediation of petroleum hydrocarbons is an important research direction. In the process of in-situ groundwater remediation, a permeable reactive barrier can effectively prevent the spread of contamination plume. However, selecting the optimal material and estimating the width remains critical and challenging problems in the design of permeable reactive barrier. Meanwhile, the site environment is also an important part to consider. In this study, aimed at the oil pollution site of a military base in South Korea, the best adsorption material was determined through batch and column experiments, and a PRB with the best width in line with the service life was designed through various design methods. In the width design, based on the material balance equation, the method of using the width of the material transport area is innovated.
