25 years later, Exxon Valdez oil spill still clings to lives, habitats

Andy Wills was sleeping on a friend’s couch in Cordova, Alaska, on March 24, 1989, ready to head out and harvest spring herring in Prince William Sound.
“My buddy had just handed me a cup of coffee in the morning and we’re watching ‘Good Morning America,’” Wills said. “And there’s the Exxon Valdez on TV, spilling oil.”
“We were like, ‘No!’ It was just the start of a nightmare,” Wills said.
The herring of Prince William Sound still have not recovered. Neither have killer whales, and legal issues remain unresolved a quarter of a century later. Monday is the 25th anniversary of the disaster, in which the tanker Exxon Valdez ran aground on Bligh Reef and spilled at least 11 million gallons of oil into the pristine waters of the sound.
Prince William Sound today looks spectacular, a stunning landscape of mountainous fjords, blue-green waters and thickly forested islands. Pick up a stone on a rocky beach, maybe a dig a little, though, and it is possible to still find pockets of oil.
“I think the big surprise for all of us who have worked on this thing for the last 25 years has been the continued presence of relatively fresh oil,” said Gary Shigenaka, a marine biologist for the National Oceanic and Atmospheric Administration.
The question of how well Prince William Sound has recovered from what at the time was the nation’s largest oil spill is a contentious one. Exxon Mobil Corp. cites studies showing a rebound.
“The sound is thriving environmentally and we’ve had a very solid, complete recovery,” said Richard Keil, senior media relations adviser with Exxon Mobil.
Government scientists have a different view.
The Exxon Valdez Oil Spill Trustee Council, a state-federal group set up to oversee restoration of Prince William Sound, considers the pink and sockeye salmon to be recovered, as well as the bald eagles and harbor seals. Several other species are listed as recovering but not recovered.
Sea otters have had a rough time. Thousands died in the months following the spill, and the population has struggled to recover in the 25 years since. The U.S. Geological Survey reported earlier this month that the sea otters of the area had finally returned to their pre-spill numbers.
Listed as still not recovering are the herring, a group of killer whales and the pigeon guillemots, a North Pacific seabird.
Rick Steiner, an oceans activist and former professor at the University of Alaska, said the “spill is not over. The damage persists in quite remarkable ways.”
Wills, who fished salmon as well as herring, said the spill left a huge mark on those who made a living from Prince William Sound.
Exxon compensation checks were too late and too little, he said.
“A lot of people got real hurt. I know a lot of guys committed suicide and all that stuff. I got divorced, had an ulcer. It was rough,” said Wills, who now runs a bookshop and cafe in Homer, Alaska.
Among the scientific puzzles of the spill, the fate of the herring is a particular mystery. It’s a vital species for the ecosystem, giving protein to whales, salmon, birds and others.
Prince William Sound was home to a lucrative spring herring fishery that supported fishermen badly in need of cash coming off the long winter in between fishing seasons.
Researchers found lesions and larval abnormalities in herring exposed to the oil. Then, four years after the spill, the herring population crashed dramatically. The reasons are a subject of intense debate, with suggestions that the effects of the spill could have made the herring vulnerable to disease.
“No other stock in Alaska crashed in 1993, so that’s indirect evidence it is spill-related,” said Jeep Rice, who studied the spill for more than two decades as a federal scientist. “That’s kind of weak, and yet it is about as good as we can get in terms of explaining why it happened in that year.”
The herring never really recovered, and the current population is too low to overcome predators. Herring fishing, with a brief exception, has been closed for more than 20 years.
The killer whales of Prince William Sound also have suffered. Two groups were hit especially hard. Scientists saw killer whales from one of the groups swimming through heavy sheens of oil. A Los Angeles Times photo showed whales from the other group swimming near the tanker as it gushed oil. Populations dropped dramatically in the year after the spill.
“The evidence is pretty compelling that it was a spill-related effect on those two groups of killer whales,” said federal marine biologist Shigenaka.
One of the groups continues its slow recovery. The other numbered 22 killer whales at the time of the spill and is down to just seven. Scientists now expect it to go extinct, the end of a genetic line that researchers say has hunted in the area for thousands of years, maybe since the last Ice Age.
The federal and state governments are still weighing the science of the spill’s effects and deciding whether to seek more money from Exxon Mobil for cleaning up remaining oil.
If there is evidence the spill is causing unexpected, continuing damage, the company could be forced to pay up to $100 million on top of the $900 million civil settlement that Exxon paid in 1991. The case lives on in the courts.
The federal and state governments have said more studies are needed, a frustration for federal Alaska District Court Judge H. Russel Holland.
“The court is dismayed that so few of the projects that the governments had expected to be completed by now have been completed,” Holland wrote in a filing last year.
Studies measuring the effects on sea otters and harlequin ducks have now been completed and are awaiting peer review before being released to the public, the federal and state governments said in their latest court filing last week. They said they are still awaiting a study on the effectiveness of techniques for lessening the remaining oil; they figure it is at least two months away from release.
The governments said they are reviewing the results of other studies and will be consulting with the Department of Justice about whether to proceed with seeking money from Exxon Mobil.
They told the judge their next update on the case will be in October, as it approaches 26 years since the Exxon Valdez became the most notorious tanker in history.
