Train derailment raising health concerns in Ohio town community

Well, two weeks after a train derailment in Ohio residents increasingly worried about what's in their air and water, they learned today a new health clinic will be opening next week to check out their symptoms. As officials insist that the testing shows the air and water is safe. Emily Schmidt has an update.

I want my town safe. She's not satisfied with environmental testing because she says you can smell chemicals as soon as you walk in her door.

Many in her community are equally worried. Even as the governor says air quality tests of more than 500 homes showed no detection of derailment contaminants. The water is safe to drink. Next week, federal and Ohio health and environmental officials will team up to examine community residents and answer any questions. The health clinic will include experts on the impacts of potential chemical exposure. Meanwhile, I'm very clear when I say as long as it takes work continues on the cleanup. An environmental protection agency document posted Wednesday said there was still potentially contaminated soil at the site.

There's a continuing NTSB investigation to CNN obtained surveillance videos which show an apparent wheel bearing overheating. No visible spark shortly before 8 p.m. the night of the derailment. Clearly visible sparks 14 minutes later. The train derailed around 8.55.

It's not clear what caused the overheating and whether it's linked to the derailment. Officials say public water is safe while well water users should stick with bottled water for now. Plenty of data, yet for many, plenty of reasons for continued concern. I'm Emma Leishmint reporting.
