The Farallon Islands Nuclear Waste Dump

If you live in the San Francisco Bay Area, you may be surprised to learn that “more than 47,800 drums and other containers of low-level radioactive waste were dumped onto the ocean floor west of San Francisco between 1946 and 1970.” (Source: The U.S. Geological Survey, a bureau of the Department of the Interior.)
