MIDLAND, Mich. (AP) -- The government has spent many millions of dollars in recent decades cleaning up sites contaminated with dioxin and, in extreme cases, relocating residents of entire tainted neighborhoods.
But tough new pollution standards proposed by the Obama administration could require additional dioxin cleanups at scores of abandoned factories, military bases, landfills and other locations declared safe years ago, officials say.
If the guidelines receive final approval this fall, federal and state officials will examine sites with known dioxin contamination, including the former village of Times Beach, Mo., where about 2,000 people were relocated, and the notorious Love Canal neighborhood of Niagara Falls, N.Y., to determine how much more work needs to be done and at what cost.
