Sponsored by: Federal Remediation Technologies Roundtable (FRTR)
The FRTR 2026 Spring General Meeting, conducted as two web-based virtual sessions, provides an opportunity to share best technical practices and results of recent technical advances in understanding and characterizing contaminant fate and migration across the GSI. The first virtual session explores current scientific understanding of key hydrological and biogeochemical processes affecting contaminant distribution and transport across a GSI. This session also explores available methods and tools for characterizing contaminant migration across a GSI. The second virtual session provides an overview of recent advances in development of innovative technologies for GSI characterization. The session ends with a discussion of needs for further technological development.
