The Environmental Protection Administration (EPA) held a meeting for discussing on draft toxic substances risk assessment technical guideline on December 14, 2000, and invited relevant organizations and agencies to discuss the contents. On December 2002, the EPA further carried out a project of verification of toxic substance risk assessment modeling to refine the draft toxic substance risk assessment technical guideline. This project was to continue the previous project, using multimedia and food chain models to proceed modeling task for a target site and assessing the feasibility of the technical guideline, so as to provide references for developers, assessors and EIA agencies. The Taoyuan RCA site was selected as the target site for study. The project conducted literature views of site geology, soil and groundwater, as well as field investigation, groundwater sampling and analysis, to collect the information for model parameter verification. Based upon the nature of the site, collected data were incorporated into MEPAS and MMSOILS to assess the transportation of the contaminants (i.e. PCE and TCE) and the risk of their impacts on the local health. At the end, this project was to provide recommendations for amendments of the toxic substance risk assessment technical guideline for the EPA’s reference.
