ORIGINAL ARTICLE:

Methane gas is the expected culprit for an explosion in the sludge concentration building at the Calumet Water Reclamation Plant in Cook County, Chicago, that injured 10 people Thursday, according to the Chicago Tribune. The plant is one of the oldest plants in Cook County located on the south side of the Windy City.

As of Friday, Aug. 31, the Metropolitan Water Reclamation District of Greater Chicago (MWRD) said all but one of the injured workers were released from the hospital.

According to the Chicago Tribune, one of the workers was rescued 20 minutes after the explosion while a second was covered by the rubble for two hours before firefighters were able to free him. In a quote to the Chicago Tribune, Fire Commissioner Jose Santiago said:

Companies had to dig 6 ft down and then tunnel their way across 20 ft to the victim.

All workers injured by the explosion were taken to nearby medical facilities where they were listed as being in serious to critical condition. One worker’s leg was trapped by a heavy beam—reports conflict as to it being metal or concrete—which was lifted off him as paramedics administered help to ensure he did not go into shock. According to CBS Chicago, those paramedics provided intravenous fluids and medication to treat him and to avoid amputation. It is not clear if amputation was needed. That worker also sustained a broken jaw in the explosion.

Among the oldest working plants in Cook County, the Calumet Water Reclamation Plant began operations in 1922. It serves 1 million people. According to the Chicago Tribune report, it is not clear how the explosion will affect long-term operations.

WWD will provide regular updates as this story develops.
