DDT is spread across a massive 17-square mile underwater Superfund site 100 feet below the ocean surface. The EPA has a new solution.
For years, the Montrose Chemical Corp. flushed a river of the pesticide DDT into Los Angeles County's sewer lines. The pesticide went where everything else in the sewer pipes went--into the Pacific Ocean about a mile or two offshore from the beautiful Palos Verdes cliffs. The EPA thinks the dump can be "capped" with clean sediment placed on top of the DDT. But no one has tried to do this before in what is the trickiest, deepest, steepest and biggest underwater site the EPA has ever worked on.
