A local pediatrician is questioning the air quality in Clairton after a second fire at the U.S. Steel coke works plant there in six months.
"It was very upsetting to see this happen and really see it impacting on children's lives," Dr. Deborah Gentile said.
Gentile said she's studied students in the Clairton school district to see if she can help improve their asthma and allergy issues.
