Triad Key Components

The Triad has three key components: systematic planning, dynamic work strategies, and real-time measurement technologies.

The Triad approach is based on three primary components.

  • Systematic Planning. Systematic planning is a planning process that lays a technically defensible foundation for proposed project activities. Systematic planning usually includes identification of key decisions to be made, the development of a CSM to support decision-making, and an evaluation of decision uncertainty along with approaches for managing that uncertainty in the context of the conceptual site model. Systematic planning is important to the success of all hazardous waste site projects whether the Triad is embraced or not, but it is particularly critical for the Triad where the use of real-time measurement technologies allow the CSM to evolve as field work is underway. The systematic planning process is described in greater detail in the section entitled Systematic Planning.

  • Dynamic Work Strategies. Dynamic work strategies are work strategies for contaminated site characterization, remediation, or monitoring that incorporate the flexibility to change or adapt to information generated by real-time measurement technologies. As information is gathered it is used to make decisions about what subsequent activities will best resolve remaining data and decision uncertainties, and/or meet cleanup goals. Dynamic work strategies assume that real-time measurement technologies are available to provide timely information. Dynamic work strategies are usually documented as pre-approved decision logic within appropriate planning documents. Dynamic work strategies are described in greater detail in the section entitled Dynamic Work Strategies.

  • Real Time Measurement Technologies. Real time measurement technologies cover any data generation mechanism that supports real-time decision-making (i.e., a dynamic work strategy), including rapid turn-around from a fixed laboratory (using either screening or more rigorous traditional analytical methods), or field-based measurement technologies. For the purposes of the Triad, the term real-time measurement technologies also includes other information gathering technologies such as non-intrusive geophysical techniques as well as supporting software and analyses (data management, review, mapping, visualization, interpretation, and dissemination) that facilitate dynamic decision-making. Real-time measurement technologies return results quickly enough to influence the progress of field activities. Real time measurement technologies are described in greater detail in the section entitled Real-Time Measurement Systems.
