Current status of soil and groundwater remediation technologies in Taiwan.

The purpose of this review is the analysis of the soil and groundwater remediation technologies referred as in situ chemical oxidation and phytoremediation, and to discuss the successes that have been made. The technology of phytoremediation has yet to be commercially accepted but shows emerging capabilities. In situ chemical oxidation (ISCO) is a frequently used technology in Taiwan for the remediation of organic compounds. Several studies have been conducted in Taiwan so show their feasibility and potential. This article reviews studies concerning these two remediation technologies. Other processes such as monitored natural attenuation, flushing, thermal treatment, or soil washing are not covered within this article.
