To facilitate the development of soil and groundwater related technologies, including investigation and remediation, Environmental Protection Administration of R.O.C.-Taiwan (TWEPA) has established a long-term technology development roadmap. The roadmap was to support the development of contaminated site management related technical tools for realization of policies and overcoming the potential technical gaps. In 2013, a study (referred as previous study here after) on contaminated site investigation and remediation technologies development, advocacy, and review strategies was defined as the cores “establishing development roadmap” and “planning advocacy strategy”. With the results of aforementioned study, this work is defined as the actions for realization of the cores. Thus, this study focused on technology development and promotion by ways of revisit the roadmap and strategy as well as recent achievement to enhance and to implement the technology development and promotion mechanism. In this study, a review on current status of soil and groundwater related technologies at international and domestic levels were conducted to revise the matrices of investigation and remediation technology. Indicators regarding technology need and maturity were designed as a screen protocol to reassure the priority of technology for future development recommended by previous study. The result indicates that permeable reactive barrier (PRB) is the technology of high priority. To act in concert with integration of contaminated sediment management in the regulation, the analysis and review of regulatory framework, technology needs, and current status of related technology were conducted. The outcomes were used for identifying the investigation and remediation technology gaps and building the technology matrix for contaminated sediment investigation and remediation. Also, the multi-year plan of technology development was revised accordingly. Following the recommendations in previous study, a pilot test on in-situ thermal remediation was carried out. In one hand, a pilot test guideline was drafted through the actual process. On the other hand, the implementation and integration of the process for long-term technology development was suggested based on the pilot test. Additionally, the feasibility of extending the coverage of current research program for soil and groundwater technology development by referring the Superfund Innovative Technology Evaluation (SITE) of USEPA was evaluated. A by-law was proposed as a future reference to the realization of pilot test support program by TWEPA. The vision include to assist the practical application of research program and to facilitate the channeling of international innovative technologies. As for technology promotion strategy, in-situ chemical oxidation (ISCO) was selected as the targeted technology for technical guideline implementation. Following the framework suggested by the previous study, guidelines of different levels of technical detail were completed for ISCO technology. Such guidelines were designed to fulfill the distinct needs of stakeholders with different technical background so that it can enhance the communication and technical understanding of the stakeholders. Also, six technical promotion events were successfully held at northern, southern, and central of Taiwan (R.O.C.) and the events were sought to deepen the penetration of technical information on future trend of technical development as well as the future pilot test program. The completion of the events was expected to strengthen long-term contaminate management program and the foundation of technical communication to stakeholders.
