SENES Oak Ridge provided technical support to the Agency for Toxic Substances and Disease Registry (ATSDR) and the National Opinion Research Center in the evaluation of human exposures, dosimetry, and health outcomes for radionuclide releases from government facilities in Hanford (Washington) to the Columbia River. The project involved the estimation of risks from radionuclide exposures via Columbia River pathways and evaluation of data relevant to planning for medical monitoring of members of the public who may have been exposed to Hanford releases between the years 1944-1972.

SENES Oak Ridge reviewed a report for the State of Colorado on the assessment of risks from exposure to plutonium and provided comments on the report's content.

SENES Oak Ridge participated in the human health risk assessment for the Clinch River/Poplar Creek Operable Unit, a major Superfund site. The studies involved risk assessments and remedial investigations of the off-site release of contaminants from the Oak Ridge Facilities, including the Oak Ridge National Laboratory, the former Gaseous Diffusion Plant (K-25), and the Weapons Production Plant (Y-12).

SENES Oak Ridge provided guidance to the Clinch River Project team on the remedial investigation of the Lower Watts Bar Reservoir near the Oak Ridge Reservation and performed a quantitative uncertainty analysis of health risks associated with the dredging scenario for Lower Watts Bar Reservoir and for the fish ingestion pathway.

SENES Oak Ridge provided assistance to the Oak Ridge National Laboratory in planning, reviewing, and performing risk assessments and wrote an introductory guide detailing the procedures for performing a quantitative uncertainty analysis. The company also performed a detailed review of the Feasibility Study/Environmental Impact Statement for East Fork Poplar Creek; contaminants of concern included mercury, PCBs, and uranium.
