The military dumped more than 8,000 tons of chemical weapons, including tens of thousands of chemical-filled bombshells and hundreds of bulk containers of chemicals, into the waters south of O'ahu in 1944 and 1945.

And it's still there.

The Army has confirmed that the dumping occurred. However, it admits it does not know exactly where all the materials were dumped and therefore has not monitored debris fields for leaks.
