(137e) Triad Case Studies Lessons Learned from Implementation at Diverse Sites

This presentation will highlight case studies in which the Triad approach was used to reduce costs and time spent in reaching project goals. The case studies represent multiple sites with diverse characteristics where each site benefited because of systematic planning, dynamic field decision strategies, and real-time measurement technologies. Case study sites to be discussed may include: contaminated sediments; brownfields; military range contamination; DNAPL; and widely dispersed, low-level contaminant plumes.

Approaches that maximize real-time analysis, rapid sampling, and dynamic decision-making lead to significant savings in both time and money spent on site cleanup. Investment in a thorough, up-front systematic planning process ensures that site data not only result in a standard consultant's report, but also advance cleanup and land re-use goals with the necessary level of confidence in supporting decisions. This approach ? integrating the use of systematic planning, dynamic strategies, and real-time measurement technologies ? is referred to as the ?Triad.? It draws together the lessons learned by practitioners over the past 25 years of site cleanup practice with the technological and knowledge advances that have occurred into a comprehensive framework. The Triad focuses on identifying and addressing all sources of uncertainty at sites and using a thorough conceptual site model to drive data collection. At the growing number of sites where Triad has been applied, a consistent theme of cost savings, shortened project timeframes, and improved decision-making is emerging.
