An Update on Progress Toward Closure at a Complex Groundwater Site

10:00 – 11:30 a.m. Pacific Time | 1:00 – 2:30 p.m. Eastern Time
Register in advance on Zoom

Seminar Abstract

The Department of Energy’s Moab Uranium Mill Tailings Remedial Action (UMTRA) project is focused on the relocation of mill tailings and the remediation of contaminated groundwater at the site of a former uranium-ore processing facility. This seminar will provide an update on progress being made through collaborations with scientific partners and regulatory agencies as the Moab UMTRA project moves towards site closure. This will include presentations of new and expanded groundwater investigations that have been completed to better understand contaminant behavior and refine remediation strategies.

This seminar builds on a case study presented during the 2023 Global Summit on Environmental Remediation. Please visit the Moab Case Study webpage to view the session recording and presentations.
