Oil plagues Sound 20 years after Exxon Valdez
Twenty years after the Exxon Valdez spilled 11 million gallons of crude oil in Alaska's Prince William Sound, oil persists in the region and, in some places, "is nearly as toxic as it was the first few weeks after the spill," according to the council overseeing restoration efforts.
"This Exxon Valdez oil is decreasing at a rate of 0-4 percent per year," the Exxon Valdez Oil Spill Trustee Council stated in a report marking Tuesday's 20th anniversary of the worst oil spill in U.S. waters. "At this rate, the remaining oil will take decades and possibly centuries to disappear entirely."
The council's findings come two decades after the March 24, 1989 disaster, when the single-hulled Exxon tanker hit a reef, emptying its contents into Alaskan waters. The spill contaminated more than 1,200 miles of shoreline and killed hundreds of thousands of seabirds and marine animals.
