Valdez Oil Spill

"Six years after the cleanup, a study was conducted to determine ecological recovery in the sound. What researchers found was that the areas that were not cleaned were in better shape – with more wildlife and cleaner water and soil – than the areas that had been cleaned. The chemicals and high-pressure washing used to "clean" the area had destroyed the ecosystem in some parts of Prince William Sound."

"The environmental disaster was the cleanup," said Pitzer.
