This 3-hour class will provide the basics of the Triad approach to site cleanup, its benefits, examples of successful implementation, and where to go for technical assistance. The Triad approach is a major initiative of EPA's Technology Information and Field Services Division that
combines systematic planning and decision uncertainty management with dynamic work strategies and state-of-the-art real-time measurement technologies. This approach lowers project costs while increasing
confidence that data are correctly interpreted so that exposure and
remedy decisions are correct. In this approach, project goals (e.g.,
site use objectives and cleanup standards) are identified and agreed
upon by all stakeholders in the planning process. A site investigation
is designed that fills the data gaps in the conceptual site model (CSM).
The investigation usually maximizes sampling density by the use of
cost-effective field-based measurement tools. A dynamic work strategy
allows the sampling and analysis to be modified in the field, based on
real-time data, to accomplish a more complete site characterization in one mobilization. The result is a more efficient program, using
state-of-the-art methods, to provide improved data, perfect the CSM, and
thus make more certain site decisions.
