Months If Not Years

BP's uncontrolled gusher is going to take a long time to fix if it gets fixed.

For those saddened by the scenes of thick oil washing into Louisiana's coastal wetlands a month after the BP oil disaster began, experts on oil spills and the coastal ecosystem have some advice: Get used to it.

The crews mopping up oil on beaches and marsh shorelines this week are fighting just the first of what will probably be a series of rolling skirmishes that will last for months, if not years -- even after the runaway well is finally capped. In fact, the untold millions of gallons of oil already fouling the Gulf off the Louisiana coast could stay in the area for at least a decade, and on the sea floor for more than 100 years.
