Cleaning up the oil-soaked wetlands may be impossible

The gooey oil washing into the maze of marshes along the Gulf Coast could prove impossible to remove, leaving a toxic stew lethal to fish and wildlife, government officials and independent scientists said.

Officials are considering some drastic and risky solutions: They could set the wetlands on fire or flood areas in hopes of floating out the oil.

But they warn an aggressive cleanup could ruin the marshes and do more harm than good. The only viable option for many impacted areas is to do nothing and let nature break down the spill.

More than 50 miles of Louisiana’s delicate shoreline already have been soiled by the massive slick unleashed after BP’s Deepwater Horizon burned and sank last month. Officials fear oil eventually could invade wetlands and beaches from Texas to Florida. Louisiana is expected to be hit hardest.

Plaquemines Parish officials on Louisiana’s coast discovered a major pelican rookery awash in oil Saturday. Hundreds of birds nest on the island, and an Associated Press photographer saw that at least some birds and their eggs were stained with the ooze. Nests were perched in mangroves directly above patches of crude.

“Oil in the marshes is the worst-case scenario,” said Coast Guard Adm. Thad Allen, the head of the federal effort to contain and clean up the spill.

Also on Saturday, BP told federal regulators it plans to stick with the main chemical dispersant it’s been spraying in the open Gulf to break up oil before it reaches the surface. The EPA had directed the company to look for less-toxic alternatives.
