San Francisco also hosts radioactive waste close by, located at the Farallon Islands[1].
> From 1946 to 1970, the sea around the Farallones was used as a nuclear dumping site for radioactive waste under the authority of the Atomic Energy Commission at a site known as the Farallon Island Nuclear Waste Dump. Most of the dumping took place before 1960, and all dumping of radioactive wastes by the United States was terminated in 1970. By then, 47,500 containers (55-gallon steel drums) had been dumped in the vicinity, with a total estimated radioactive activity of 14,500 Ci. The materials dumped were mostly laboratory materials containing traces of contamination. Much of the radioactivity had decayed by 1980.
And the "USS Pandemonium" at Treasure Island in the middle of the San Francisco Bay.
A ship they built on land that they could apply radioactive contamination then teach sailors how to clean it up. Then dump it all out into the bay. Contaminated soil is still being discovered as recently as 2013 on Treasure Island where they have built housing.
