Nation's Worst Superfund Sites

"Thirty-four military bases shut down since 1988 are on the Environmental Protection Agency's Superfund list of worst toxic waste sites -- most of them for at least 15 years -- and not one is completely cleaned up.

...Of the $23.3 billion in costs from four previous rounds of base closures and realignments, the Pentagon has spent $8.3 billion so far on pollution cleanups and other compliance with environmental laws, congressional investigators say. EPA officials say it will be at least a decade before many are completed -- at a cost the government estimates will reach an additional $3.6 billion."
