Last week, officials admitted that at least six Hanford tanks are currently leaking. "The government promised 10 years ago that it's under control. Now we realize it's not," CUNY physics professor Michio Kaku told CBS News this week.

But news of the latest leaks isn't surprising to the 60 Minutes team that reported in 2006 on Hanford's problems, including the many construction errors made at the facility. Watch Lesley Stahl's report in the above video player to learn about the mind-boggling mistakes made at the site, like the decision to build a pretreatment facility for radioactive waste that wasn't designed to withstand an earthquake.

And if you're wondering about an updated cleanup timeline of what amounts to 80 Olympic-sized swimming pools of the toxic brew, it's estimated that it will take at least 40 years at a cost of more than $100 billion.
