Abstract
This paper summarizes the management system for the control of soil remediation programmes in Taiwan. This system includes subsystems which are linked together in order to make the remediation process more cost-effective and efficient. The subsystems include: (1) site discovery and identification using a monitoring and information system; (2) a preliminary assessment and site inspection system to establish a national priority list (NPL) for remedial action; (3) a response and control system; (4) a remedial investigation and feasibility study (RI/FS) and detailed evaluation of remedial action alternatives; (5) responsibility for financial support; and (6) the release of sites from the NPL and their transfer to other land uses. In other words, the key components of this management system include soil remediation law and related legislation, alternative techniques for soil remediation, financial support, and guidelines or criteria for soil remediation. For cost-effectiveness and efficiency in the selection of soil remediation techniques, key factors are considered, including initial contaminant concentrations and soil characteristics, materials handling and preprocessing techniques, treatment goals, and mixtures of organic and inorganic contaminants. An acceptable solution may involve the use of several treatment technologies in a treatment train. Some case studies of soil remediation management of sites in Taiwan polluted by trace elements, particularly cadmium and lead and organic pollutants, are discussed.
