The Center for the Remediation of Complex Sites (RemPlex) was pleased to present the 2023 Global Summit on Environmental Remediation, organized in cooperation with the International Atomic Energy Agency (IAEA), from November 13-17, 2023, at Pacific Northwest National Laboratory in Richland, Washington State, USA.

Nearly 150 people joined us—in person and virtually—for this international forum on the challenges, barriers, and innovative solutions for successful remediation and long-term stewardship of contaminated sites.

The RemPlex Summit brought together participants from government, industry, and research institutions to discuss remediation challenges and to collaborate on the application of both proven and innovative solutions. The integration of international case studies and technical sessions (oral and poster sessions), training workshops, and site or facility tours will provide networking and knowledge-sharing opportunities related to persistent and challenging issues facing the international environmental remediation community.
