Toxic waste dump site more than twice the size of Manhattan discovered in Pacific Ocean

Stephanie Sy, PBS News Hour

A massive underwater toxic waste site has long been suspected off the Southern California shore, since industrial companies used the ocean as a dumping ground until 1972. Now marine scientists have identified over 25,000 barrels they believe contain the toxic chemical "DDT" in the Pacific Ocean. Stephanie Sy talks to David Valentine, a UC Santa Barbara professor of microbiology, about the barrels.
