Nuclear meltdown covered up for decades.

Santa Susana Field Laboratory. It was picked up by Boeing when they acquired Rocketdyne and I had the pleasure(?) of visiting a few times. The building I visited was across the street from where the meltdown had occurred, but it had a separate history of some nuclear contamination. All of it had been allegedly cleaned up, except that we were all instructed to never use the running water for anything but flushing the toilet.

Boeing was pretty stupid to accept the SSFL as part of the Rocketdyne deal because they assumed liability for cleaning it up. Someday, if it ever gets cleaned up enough, the State of California will take over the land and make it into a public park.

Also this documentary was made recently:
