Valdez Spill: 11 Million Gallons Poisoned Alaska
24 Mar
Summary
- The Exxon Valdez spilled 11 million gallons of crude oil in 1989.
- The disaster polluted 1,300 miles of Alaskan shoreline.
- Cleanup efforts cost billions, wildlife suffered immense losses.
On March 24, 1989, the supertanker Exxon Valdez ran aground in Alaska's Prince William Sound, unleashing approximately 11 million gallons of crude oil. The vessel sliced into Bligh Reef, spilling about one-fifth of its cargo into the pristine waters.
Initial containment efforts were hampered by delays, strong winds, and waves, which dispersed the North Slope crude oil. The spill ultimately contaminated an estimated 1,300 miles of shoreline and waters, extending as far south as the Shelikof Strait.
The extensive cleanup operations cost billions of dollars. Despite these efforts, the disaster caused immense harm to native wildlife, impacting populations of salmon, herring, sea otters, bald eagles, and killer whales.
This event stands as one of the largest oil spills in history, surpassed by the BP oil well rupture and the Ixtoc I spill off Mexico's coast. In a separate incident 32 years later, a massive cargo ship blocked the Suez Canal for six days.
