They came at a time of need.

After the floods, hundreds of people had nowhere to go so FEMA brought in mobile homes.

FEMA promised Congress there would be no more toxic trailers, like the ones that made so many sick on the Gulf Coast.
CBS 2 releases the results of air tests inside those homes.
CBS 2's Megan Terlecky has the story you'll only see on kgan.com and CBS 2.

Megan has been working on this story for awhile; talking with the people who live inside these homes and their worries about their flooded homes. The last thing on their minds was the condition of the FEMA home's they are living in, but now it's the only thing they can think about.

Using test kits from a reputable lab; we asked dozens of eastern Iowans living in FEMA mobile homes if we could use this test to determine what's in their air.

The big concern, formaldehyde.

And what we found sent FEMA scrambling...

The state of Iowa is now asking questions, and now people are questioning the roofs over their heads.

Thirty percent of the homes we tested: unsafe

But that's not all when we tried to help those with alarming levels get in touch with FEMA, even we couldn't believe what happened. The phone number had been disconnected.
