An explosion at the Nut Island Headworks sewerage-screening facility in Quincy, Mass., injured five workers on Jan. 25. “There was an explosion and subsequent fire in the facility three stories down,” says a spokeswoman at the Massachusetts Water Resources Authority, which owns the facility. All five workers were able to exit and are in stable condition. Raw sewage—120 million gallons per day in the winter—flows through the headworks from 20 communities. At press time the fire was still burning and a 50-ton crane was being brought in to lift heavy concrete ceiling slabs to allow the fire department to douse the fire. The Quincy Fire Dept. is conducting the initial investigation.
