This training workshop will present an overview of the relationships and interactions between groundwater and surface water bodies, giving participants a greater understanding of potential exposure scenarios. Discussions will focus on developing effective conceptual site models and how to collect useful data from the hyporheic zone, with case study examples. The training will end with a panel discussion and direction to EPA resources.

This workshop’s content is directed toward Federal, State, Tribal, and University-level scientists, particularly hydrogeologists, ecologists, risk assessors, remedial project managers (RPMs), National Environmental Policy Act (NEPA) project reviewers, Tribal Specialists, EPA Superfund Technical Liaisons (STLs), EPA Regional Science Liaisons (RSLs), EPA Regional Science Councils (RSCs), and those involved with underground storage tanks.
