what was the effect of the exxon valdez oil spill disaster
Environmental Effects of Exxon Valdez Spill Still Being Felt. On March 24, 1989, the Exxon Valdez ran aground in northern Prince William Sound, spilling 42 million liters of crude oil and contaminating 1,990 kilometers of shoreline. Some 2,000 sea otters, 302 harbor seals and about 250,000 seabirds died in the days immediately following the spill. Now researchers writing in the journal Science caution that more than a decade later, a significant amount of oil still persists and the long-term impacts of oil spills may be more devastating than previously thought.
