Exxon Valdez Oil SpillOn March 24, 1989, the tanker Exxon Valdez grounded on Bligh Reef in Alaska's Prince William Sound, rupturing its hull and spilling nearly 11 million gallons of Prudhoe Bay crude oil into a remote, scenic, and biologically productive body of water. It was the largest single oil spill in U.S. coastal waters.

Exxon Valdez oil spill …occurred in Prince William Sound, Alaska, on March 24, 1989, when the Exxon Valdez, an oil tanker bound for Long Beach, California, struck Prince William Sound's Bligh Reef and spilled 260,000 to 750,000 barrels (41,000 to 119,000 m3) ofcrude oil.[1][2] It is considered to be one of the most devastating human-causedenvironmental disasters ever to occur in history.[3] As significant as the Valdez spill was — the largest ever in U.S. waters until the 2010 Deepwater Horizon oil spill — it ranks well down on the list of the world's largest oil spills in terms of volume released.[4]Revision on
