Richland, Washington is a company town that sprang up almost overnight in the desert of South Eastern Washington. Its employer is the federal government, and its product is plutonium. The Hanford nuclear site was one of the Manhattan Project sites, and it made the plutonium for the bomb that devastated Nagasaki. Here, the official history is one of scientific achievement, comfortable houses, and good-paying jobs. But it doesn’t include the story of what happened after the bomb was dropped — neither in Japan, nor right there in Washington State. On part one of our two-part season finale, we tell the largely-forgotten story of the most toxic place in America.
