The chemical remains in its most potent form in startlingly high concentrations, spread across a wide swath of seafloor larger than the city of San Francisco.<\/p>\n<p>\u201cWe still see original DDT on the seafloor from 50, 60, 70 years ago, which tells us that it\u2019s not breaking down the way that [we] once thought it should,\u201d said UC Santa Barbara scientist David Valentine, who shared these preliminary findings Thursday during a research update with more than 90 people working on the issue. \u201cAnd what we\u2019re seeing now is that there is DDT that has ended up all over the place, not just within this tight little circle on a map that we referred to as Dumpsite Two.\u201d<\/p>\n<p>These revelations confirm some of the science community\u2019s deepest concerns \u2014 and further complicate efforts to understand DDT\u2019s toxic and insidious legacy in California.
