[Triad, a new approach for contaminated site management]

Remediation of a contaminated site is typically a time-consuming and expensive process. The traditional multistage approach of site management is an important contributor of this lengthy and costly process. The emergence of new characterization technologies and past experiences have led to the development of a new site characterization and remediation approach-Triad approach. In this paper, the three key components of the Triad approach, namely, systematic project planning, dynamic work strategy, and real-time measurement, were elucidated. The advantages and applicability of the Triad approach were demonstrated with case studies. Based on the currect practices of site characterization in China, recommendations are made to promote the application of the Triad approach.
