The Columbia River flows through about 50 miles of the site. Radioactive and hazardous contamination from decades of producing nuclear materials for the nation's defense have migrated through the soil into the groundwater, which generally flows toward the river. In November 2005, GAO reported on the potential for the Hanford site to contaminate the Columbia River. To address continuing concerns, GAO reviewed the status of DOE's efforts to (1) understand the risk to the Columbia River from Hanford site contamination and to deploy effective technologies to address contamination near the river and (2) strengthen the management of its river protection program. To assess DOE's efforts, GAO reviewed numerous reports by DOE and others, and discussed the problem with federal and state regulators and DOE officials. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-06-1018/html/GAOREPORTS-GAO-06-1018.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-06-1018/pdf/GAOREPORTS-GAO-06-1018.pdf GAO-06-1018 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-06-1018 Other Written Product GAO-06-1018; Nuclear Waste: DOE's Efforts to Protect the Columbia River from Contamination Could Be Further Strengthened; Contaminants Contamination Environmental cleanups Environmental protection Groundwater Nuclear waste management Program evaluation Program management Radioactive waste disposal Rivers Soil pollution Water pollution Water pollution control Columbia River (WA) DOE Hanford Tri-Party Agreement
