Visiting the City That Built the Hanford Nuclear Site

As my plane approaches the Tri-Cities Airport in south-central Washington state, the sandy expanse outside my window gives way to hundreds of bright green circles and squares. From this semi-arid terrain springs an irrigated oasis of potatoes, hops, peaches, and sweet corn. Just beyond our view is one of the most contaminated places in the world: the Hanford Site, home to 177 aging tanks of radioactive waste.
