The dust has settled from a methane explosion last month that brought down the roof of a sludge concentration building at the Calumet water reclamation plant on Chicago’s far south side, but there is still uncertainty as to what triggered the blast.
The roof of the sludge concentration building at Chicago's Calumet Water Reclamation Plant collapsed at around 11 a.m. August 30. Ten people were hurt and successfully evacuated to area hospitals for treatment by the Chicago Fire Dept.
Connecticut’s highest court in November rejected the claims of workers seeking lost wages as a result of a 2010 explosion at a power-plant under construction.
