Suspected DDT dumpsite found off California

The transcript discusses the discovery of over 25,000 barrels containing DDT off the Southern California coast near Catalina Island. These barrels were found by autonomous underwater vehicles at a depth of 3000 feet. An expert suggests that if the barrels have not leaked, they could be moved to a safer disposal area. DDT, developed in the 1940s as an insecticide, was banned in 1972 due to its harmful environmental effects and is now classified as a probable carcinogen. Previous studies have shown DDT presence in the water and its impact on marine life, raising concerns about its long-term effects.
