Hurricane Ike's winds and massive waves destroyed oil platforms, tossed storage tanks and punctured pipelines. The environmental damage only now is becoming apparent.
According to an analysis of federal data by The Associated Press, at least a half million gallons of crude oil spilled into the Gulf of Mexico and the marshes, bayous and bays of Louisiana and Texas.
In the days before and after the deadly storm, companies and residents reported at least 448 releases of oil, gasoline and dozens of other substances into the air and water and onto the ground in Louisiana and Texas.
According to the AP's analysis, the hardest hit places were industrial centers near Houston and Port Arthur, Texas, as well as oil production facilities off Louisiana's coast.
The Coast Guard, with the Environmental Protection Agency and state agencies, has responded to more than 3,000 pollution reports associated with the storm and its surge along the upper Texas coast.
Most callers complain about abandoned propane tanks, paint cans and other hazardous materials containers turning up in marshes, backyards and other places.
No major oil spills or hazardous materials releases have been identified, but nearly 1,500 sites still need to be cleaned up.
