| Summary: | 碩士 === 朝陽科技大學 === 環境工程與管理系碩士班 === 93 === The contaminations caused by the leakage of oil storage tank are getting more and more serious based on EPA’s survey. Most of storage tanks are built on the ground. If the leakage happens, the oil will be contained inside the dike area on the surface and then leach into soil by gravity. Both soil and water will be contaminated by the oil and required remediation treatment. Prior to any treatment can be conducted, a screening process has to perform. In this study, several screening procedures have been made for a specific site. A Risk-Based Corrective Action (RBCA) was first applied to evaluate the risk for human health. After more geology data were provided, a flow simulation model was build.
Based on the results, it is shown that benzene has the most impact on the human health and benzene will be treated as an index chemical for further study. In the sensitivity study for the simulation model, hydraulic conductivity is the most sensitive parameter in this model besides oil physical properties. Water table is the second one. It is found That the model inside RBCA only suitable for homogeneous aquifer. More complicated model needs more geology data such as hydraulic conductivity. It means more measurements are required and may update the model based on new corrected data.
