To ensure the complete and timely cleanup of the Hanford Nuclear Site, we review and critique cleanup and restoration plans.

We write comment letters detailing our analyses, publish articles and blog posts, and prepare fact sheets to help others understand the plans and how to protect the Columbia River. By clicking the links below, you can view and download our work.

Explore "Water's Walk Through Hanford"

The Hanford Nuclear Site is the most contaminated place in the Western Hemisphere and the most long lived threat to the health of the Columbia River. Learning about Hanford can often feel overwhelming and confusing, especially for middle and high school youth, but it doesn’t have to be! Columbia Riverkeeper’s new interactive story map, “Water’s Walk Through Hanford,” breaks down some of the most dangerous pollutants and cleanup areas at Hanford, bringing the cleanup to life.

The Birds of Hanford

Much more than a nuclear waste site, over 258 species of birds call the Hanford Reach home

Historic Hanford

The 586‐square‐mile Hanford Nuclear Site is a legacy of World War II and the Cold War.

In 1943, the federal government selected Hanford as a top‐secret site for the Manhattan Project, which called for enriching plutonium for nuclear weapons. Located in a sparsely populated area in south‐central Washington State near the city of Richland, the federal government quickly evacuated and condemned the small towns of White Bluffs and Hanford. The government also denied access to Native Americans who lived along the river and had historically used the area for fishing, hunting, food gathering, and religious purposes. Within a year, the U.S. constructed the world’s first large-scale nuclear reactor. In August 1945, concentrated plutonium manufactured at Hanford powered the nuclear bomb dropped on Nagasaki, Japan.

The United States eventually built nine nuclear reactors along the Columbia River to produce plutonium and other materials. The river provided electricity from the Grand Coulee Dam and abundant water to cool the nuclear reactors.

From 1943 to 1989, the federal government generated unprecedented volumes of hazardous and radioactive waste. For example, Hanford released approximately 725,000 curies of radioactive iodine‐131 between 1944 and 1957. In contrast, the 1979 famous accident at the Three Mile Island nuclear power plant in Pennsylvania released between 15 and 24 curies of iodine‐131.

During Hanford’s operation, the federal government disposed of hundreds of millions of gallons of radioactive waste directly into the ground—injection wells, trenches, and buried drums. D.O.E. also placed waste in 177 large underground tanks, many of which are now leaking. The United States also discharged contaminated cooling water into the Columbia River from the nuclear reactors, which contained about 110 million curies of mostly short‐lived radionuclides. Hanford operations also resulted in air emissions of approximately 20 million curies from 1944 to 1972. Citizens downwind report increased rates of thyroid cancer as a result of the iodine releases.
