How America Poisoned a City of 50,000 With Nuclear Waste: Hanford, Washington

In 1943, the federal government condemned 586 square miles of farmland along the Columbia River in Washington State, evicted 1,500 residents in thirty days, and built the world's first plutonium production complex in secret. Within two years, the Hanford Engineer Works — a $230 million construction project employing 51,000 workers — had produced the plutonium core for the atomic bomb dropped on Nagasaki. The nearby company town of Richland, built from scratch by DuPont and the Army Corps of Engineers, swelled from 247 people to 25,000 and became one of the strangest government-owned cities in American history: a place where the federal government was your landlord, your employer, and the only institution you were never allowed to question. What the residents of Richland and the farming communities downwind of Hanford did not know was that from 1944 to 1957, the facility released over 740,000 curies of radioactive iodine-131 into the atmosphere — settling on pastures, concentrating in milk, and irradiating the thyroid glands of children across eastern Washington. In 1949, a classified Air Force experiment called the Green Run intentionally released up to 12,000 curies in a single night, five hundred times the amount released during the Three Mile Island accident. The Columbia River, used as reactor coolant and waste disposal system simultaneously, received 7,000 to 20,000 curies of radioactive contamination per day throughout the 1950s. None of this was disclosed until 19,000 pages of classified documents were released under the Freedom of Information Act in 1986. Today, 56 million gallons of radioactive waste sit in 177 underground tanks on the Hanford site, at least three of them actively leaking. More than $58 billion has been spent on cleanup. The estimated cost to finish: up to $640 billion. For every dollar spent building Hanford, more than a hundred will be spent trying to undo the damage.
