It wouldn’t be the company’s first offense. In 2000, the pesticide manufacturer faced a superfund lawsuit for discharging millions of pounds of DDT into Los Angeles County sewers that poured into the Palos Verdes Shelf between 1947 and 1971. But, the barrels were never mentioned in the lawsuit, reports Gizmodo.
Using a deep-sea robot and a hunch, Valentine and his team first found barrels seeping toxic waste 3,000 feet deep in the sea in 2011 and 2013 by happenstance while working on other research endeavors. Old records and shipping logs revealed that between 1947 and 1961, 767 tons of DDT were potentially tossed into the ocean, according to the LA Times’ 2020 investigation.
