The purpose of this project is to develop a methodology to optimized identify the groundwater pollution source and contaminant release history. To achieve this main goal, groundwater flow and contaminant transport models are used to forward simulate pollution transport underground in the beginning; and together with an optimization method, the inverse problem are solved by repeating solving the forward problem with different parameters, source locations, and release history. Several works had been down, including: related paper review and report collection, establish the procedure to assess groundwater models, create an optimization model to identify the pollution source and contaminant history, apply the source identification method to real pollution cases to prove its practicability. In the end, the standard operation procedure for source identification is given for further application in soil and groundwater remediation and environment protection.
