Pollution controls damaged by a Christmas Eve fire are working again. But many people in nearby communities are still feeling the effects — and worrying about their health.

Some people, including Clairton’s mayor, said they didn’t hear about the fire — and the air quality problems — until more than two weeks after the fire.

East Liverpool, just across the Pennsylvania border northwest of Pittsburgh, has a history of welcoming polluting businesses because people need the jobs. But some residents fault city leaders and regulators for failing to protect them.
