They're scattered all around the United States, more than 1,200 of them,
waiting for cleanup. Some are old military bases or abandoned factories.
Others are gas stations with leaky underground tanks. And they're only

Over the next 30 years, the US may have to clean up as many as 350,000
Superfund sites at a cost of up to $250 billion, according to the US
Environmental Protection Agency.

How will taxpayers pay for that?

One solution is to find cheaper cleanup technologies. One of the most
promising innovations right now involves microscopic iron particles. At
least four teams of researchers are using these "nanoparticles" to
attack some of the most vexing underground pollutants, including
chromium-6, the groundwater pollutant made famous in the movie "Erin Brockovich."
