"HANFORD SITE, Wash. – Seven decades after scientists came here during World War II to create plutonium for the first atomic bomb, a new generation is struggling with an even more daunting task: cleaning up the radioactive mess."
"The U.S. government is building a treatment plant to stabilize and contain 56 million gallons of waste left from a half-century of nuclear weapons production. The radioactive sludge is so dangerous that a few hours of exposure could be fatal. A major leak could contaminate water supplies serving millions across the Northwest. The cleanup is the most complex and costly environmental restoration ever attempted.
And the project is not going well.
A USA TODAY investigation has found that the troubled, 10-year effort to build the treatment plant faces enormous problems just as it reaches what was supposed to be its final stage."
