Computer assisted data management techniques applied to Triad investigations
• Data Visualization– Help convert “data” into useful information.
– One tool does not fit all.
– Many users and purposes
• Database – In order to make the TRIAD approach work, we need to process more
data faster. – Well organized databases provide an effective tool to store data in a
powerful retrieval system.– Automation where possible.
• Conceptual Site Model– Dynamic Work Strategies—flexibility in the face of new information.
– Knowledge Transfer—Scientist to management to public.
– Social Capital—overcome sense of mistrust.

Conceptual Site Model
• The Conceptual Site Model (CSM) is at the core of the systematic planning process.
– Clearly identify project decisions & end points.
– Articulate project specific decision statements.
• Project life cycle activity that is interactive in nature, structured so that project adjustments & course corrections can take place.

Data VisualizationData visualization is key to making data understandable in the Triad Approach.
Knowledge Transfer—Scientist to management to public.
Social Capital—overcome sense of mistrust.
Share Results—convert “data” into useful information.
Decision Support System—should make it simple to visualize data from many sources and analyzed using the appropriate environmental analytic applications for the particular problem.

• Laboratory Issues / Data Validation:– CLP data, validation through certification
– Other Lab data, lab validation checked independently
– Most lab data…not so much…• So why such high reliance on “formal” methodology?
– Mix n match analytic methods—total + dissolved?
– Heterogeneity- Almost all sites are a complex system of soil, groundwater, surface water, etc., that interact w/chemicals released into the environment
– Extrapolating small data sets to reflect larger portions of matrix is almost ALWAYS inaccurate & misleading
Comparative Issues

• QA of Triad Field Methodology:
– Still not fully trusted
– Regulatory technical requirement documents could reduce RP uncertainty leading to increased Triad implementations.
• Research still needed:
– Documented cost comparisons
– Reliability and validity demonstrations
– Historic fill areas
– Northeast fly-ash deposition
