Following earlier work conducted in the 2012 and 2013 GSR Project. This project is composed of four main contents, GSR evaluation of demonstration sites, trial test of the GSR certification system, trial test of innovative green investigation technology and GSR promotion. The project adopted the framework and tools developed by the Taiwan EPA for GSR evaluation and selected Site F, Site P and Site T as demonstration sites. The content of GSR evaluation was planned according to each site condition, which generally include environmental footprint assessment, human health risk assessment, economic impact evaluation, stakeholder survey, and BMPs planning. The three demonstration sites of the previous project were tracked as well to understand GSR related issues. Results showed the remedial operation and maintenance phase had the highest environmental footprint. For human health risk of remedial staff, all of the sites had acceptable risk except Site T. Based on the GSR evaluation results, this project proposed feasible BMPs for each demonstration site. On the other hand, in order to understand the applicability of the GSR certification system protocol. This project applied the protocol to the demonstration sites and held expert meetings to evaluate the rationality of the scoring system. The study encourage to apply the certification system to different kinds of sites to identify unsuitable indicators and approaches to adjust the weighting of each indicator. To enhance the quality of the investigation and remediation work. This project introduced an innovative green investigation technology – tree core analysis and conducted trials in 3 contaminated sites in the country and the protocol for tree core sampling and analysis was established. The results indicated that tree core analysis can reflect the contamination condition of the subsurface and can help to delineate the contaminated area. In addition to GSR evaluation of demonstration sites, this project also established a GSR website for GSR promotion. All of the evaluation tools were integrated into the website as well as GSR related documents, links and news. During the project, project members also participated the SuRF-International conference calls and other activities to ensure our country can acquire the most updated GSR global news.
