It was March 24, 1989 when one of the largest oil tankers ever built left the terminal in Valdez, Alaska, with almost one and a half million barrels of crude oil in the hold. The Exxon Valdez was a steel colossus: three hundred meters long, fifty meters wide, an engine of over twenty-four thousand kilowatts. Built just three years earlier in San Diego and entrusted to the ExxonMobil company, it was destined to follow a routine route south, crossing the waters of Prince William Sound. Nothing that evening gave any indication of what was about to happen.
Navigation immediately encountered a small complication: some icebergs at the mouth of the strait forced Commander Joseph Hazelwood to request a change of course from the coast guard. A manageable deviation in itself, but it triggered a chain of events that was difficult to stop. Hazelwood, after having set the new trajectory, abandoned the bridge, leaving the ship in the hands of the third officer and a member of the crew who had not completed the mandatory six-hour rest required before a watch. Two tired people, on a huge ship, in waters that are anything but simple.
The disaster strikes at midnight
Around midnight, the turn necessary to return to the safe route occurred with a fatal delay. The Exxon Valdez hit the Bligh Reef, a reef in the strait, with all its mass. The single-layer hull, a technology already considered vulnerable at the time, did not withstand the impact. Within minutes, approximately forty-two million cubic meters of crude oil began pouring into the frigid waters of Alaska. A disaster that is measured in tens of millions of liters of oil, expanded in a dark and suffocating stain destined to reach almost two thousand kilometers of coast.
In the ensuing trial, a picture that was as serious as it was disheartening emerged. Hazelwood, the judges found, had consumed several glasses of vodka before leaving: his judgment was compromised when he made the crucial decisions of the evening. The chain of responsibility turned out to be entirely broken, from top to bottom.
A broken ecosystem
Prince William Sound was no ordinary stretch of sea. Its waters hosted one of the richest and most intact marine ecosystems of the entire American continent: jagged reefs, protected inlets, seabeds abundant with life. It was precisely the conformation of that coast, so beautiful, so complex, that turned into a trap. The oil seeped into every crevice, settled on the rocks, penetrated the sediments. Cleaning up those creeks proved to be a titanic and, to a large extent, impossible task.
Estimates of animal losses still remain difficult to read without dismay. Between two hundred and fifty thousand and half a million seabirds died, depending on the sources. The otters killed were estimated at between one thousand and three thousand, the seals around three hundred, the bald eagles two hundred and fifty. Twenty-two orcas also perished, and then billions of salmon and herring eggs, invisible but fundamental to the balance of the entire local food system. Species that take decades to rebuild their populations, environments that never completely go back to the way they were before.
More than 30 years after the oil spill, the following species remain in a “Not recovering” or “Unknown” status:
The most expensive cleanup in history (and it wasn’t enough)
ExxonMobil immediately implemented what was defined at the time as the most massive environmental cleanup operation ever attempted. About two billion dollars spent to try to return Alaska’s coasts to something similar to their original condition. Thousands of operators, special equipment, experimental techniques. Yet, years later, scientific studies have returned a balance that is anything but reassuring.
Research by the National Oceanic and Atmospheric Administration published in 2007 estimated that nearly one hundred thousand liters of oil were still trapped in coastal sediments in the area. Subsequent analyses, conducted in 2013, detected traces compatible with chronic hydrocarbon poisoning in the tissues of local otters. Not all scholars agree on the extent of the residual risk: some researchers maintain that the polluting substances are now found in marginal areas rarely frequented by fauna. But the doubt remains.
Responsibility, compensation and a sentence that was too lenient
On the legal front, ExxonMobil was sentenced in both civil and criminal cases for a total of more than $1 billion — at the time the highest compensation ever imposed for an industrial disaster, surpassed only in 2012 when BP paid four and a half billion for the Deepwater Horizon accident. But it was the fate of Commander Hazelwood that left public opinion more than a little perplexed: despite having been identified as the main person responsible for the incident, he got away with a suspension from his navigation licence, a fine of fifty thousand dollars and a thousand hours of community service to be carried out on land.
The accident forced the US government to fundamentally review oil tanker safety regulations, introducing a double hull requirement for new constructions — a measure that would likely have contained the scale of the disaster had it already been in place that night. It was a lesson paid at a very high price.
A wound that doesn’t close completely
Over thirty years later, the name Exxon Valdez has firmly entered the lexicon of environmental disasters, becoming a symbol of negligence, failure to prevent and systemic fragility. The ship itself, after being repaired and renamed several times, changed owners and destinations until being dismantled in India in 2012. But the memory of that night in Alaska remained far more lasting than the hull that had caused it.
That story tells us something that goes beyond the news of a shipwreck: it reminds us that certain ecosystems, once compromised, never fully recover. And that sometimes only a few hours pass between a wrong decision made on a control panel and an environmental catastrophe.
