WASHINGTON — A new government report details 87 shipwrecks — most sunk during World War II decades ago — that could pollute US waters with tens of millions of gallons of oil.
Even so, the potential for pollution is less than scientists had expected. The report released Monday by the National Oceanic and Atmospheric Administration concludes ‘‘the scope of the problem is much more manageable than initially feared. . . . Our coastlines are not littered with ‘ticking time bombs.’’’
