Mercury (Hg) losses at and near the Y-12 National Security Complex have caused elevated levels in water and fish from East Fork Poplar Creek (EFPC). DOE is using a phased, adaptive management approach to Hg remediation at Y-12, with a focus in the next few years on construction of the Mercury Treatment Facility (MTF) to treat the most contaminated Y-12 outfall entering the creek. Once operational, the MTF will provide additional protection against inadvertent releases of Hg into the stream from decontamination and decommissioning of Y-12 Hg-use buildings. A major focus of the project has been on understanding Hg transport and fate processes in the EFPC system so that targeted, site-specific technologies can be developed. Field study data are used to define conceptual and quantitative models for EFPC to inform future remedial decision-making. Bench-scale technology development activities are also presented. https://info.ornl.gov/sites/publications/Files/Pub114693.pdf
