Environmental Chemistry Consulting Services: Your Partner In Success

Resources  |  Triad Resources

Triad is defined by the U.S. EPA as being a technically defensible methodology for managing decision uncertainty that leverages innovative characterization tools and strategies.

  • Managing decision uncertainty is the foundation of the Triad framework.  There is a popular assumption that analytical uncertainty is the most significant contributor to overall project uncertainty.  While poor analytical quality can in fact have material impacts on your project success, "poor" data quality is not the norm but the exception.  What is more important is to have data of KNOWN quality.  There is clear evidence in published literature and in our experience that analytical uncertainty is more often than not a small contributor project uncertainty, often dwarfed by sampling uncertainty, i.e., "representativeness."

  • Innovative characterization tools, more often than not offering "real time" or "just in time" results, is one of the three legs of the Triad framework.  ECCS is focused at providing onsite analytical, either as the primary onsite tool or supplemental to other technologies.  A critical aspect of selecting any innovative tool is to perform a demonstration of method applicability, where necessary.

One exceptional starting point for further information on the Triad approach is Triad Central.  This website has an extensive library of literature, guidance documents, and case studies.  Contact ECCS early in the process and make us part of your systematic planning team.  In most instances we do not charge for this service and find that it is critical toward fullfilling our company mission - your project success!

In lieu of exiting our website to other Triad resources, below are some of the more informative documents that we have collected on the subject.

In Search of Representativeness: Evolving the Environmental Data Quality Model, 2001/ 2002

Argues that the first generation data quality model that equated environmental data quality with analytical quality was a useful starting point, but it is insufficient because it is blind to the repercussions of multi-faceted issues collectively termed ‘‘representativeness.’’

Presents a very critical and technical subject in a conversational tone.
