Triad Overview

Summary of the Triad approach to decision-making for hazardous waste sites.

The Triad approach to decision-making for hazardous waste sites offers a technically defensible methodology for managing decision uncertainty that leverages innovative characterization tools and strategies. The Triad refers to three primary components, systematic planning, dynamic work strategies, and real-time measurement systems. If you are unfamiliar with the Triad, follow the links to learn more about what makes the Triad different from traditional approaches, key Triad concepts, requirements for successfully implementing a Triad approach, and the benefits one can expect from implementing the Triad. An EPA publication, "Summary of the Triad Approach" (PDF, 38 KB) also provides an excellent synopsis of the Triad.

Technological advances in field analytical methods combined with experiences gained from historical hazardous waste site cleanup work have led to the EPA's Triad approach to hazardous waste site characterization, remediation, and closure.
The Triad manages hazardous waste site decision-making uncertainty through systematic planning, dynamic work strategies, and real-time measurement technologies.
There are a number of factors (e.g., appropriate QA/QC, flexible contracting, stakeholder concurrence, etc.) that contribute to successful Triad implementations.
The Triad approach can accelerate project schedules, reduce overall project costs, and improve project outcomes.
