Although DDT, dichlorodiphenyltrichloroethane, was banned 50 years ago,
its toxic — and insidious — legacy continues to haunt the marine ecosystem
off the California coast.

Public calls for action have intensified since The Times reported that the nation’s largest manufacturer of DDT once dumped its waste into the deep
ocean near Catalina Island. This pollution bubbling 3,000 feet under the
sea remained hidden until a new generation of scientists discovered the evidence.

Significant amounts of DDT-related compounds are still accumulating today
in Southern California dolphins and California’s critically endangered
condors, and a recent study linked the presence of the chemical to an aggressive cancer in sea lions. Another study based in Oakland found that
DDT’s hormone-disrupting effects are affecting a new generation of women — passed down from mothers to daughters, and now granddaughters.

L.A.'s coast was once a DDT dumping ground. No one could see it — until
now
A new generation of scientists have uncovered barrels containing DDT, a
toxic pesticide banned decades ago, dumped into the deep ocean.

humans.

A team of Scripps and NOAA researchers set sail to map the seafloor for
DDT waste barrels dumped decades ago. As many as half a million of these barrels could still be underwater today.

History of DDT ocean dumping off L.A. coast even worse than expected, EPA
finds
Barrels of DDT waste — along with other chemicals — were likely poured
directly into the ocean near Catalina Island, according to federal
regulators.
