The story revealed that workers at the city of Detroit's sewage treatment plant were being exposed to incinerated sewage sludge ash that contained a variety of heavy metals and other hazardous material. These materials included dangerous levels of silica, a human carcinogen that also causes the debilitating lung disease silicosis. Workers alleged that because of malfunctioning equipment they had been breathing the contaminated ash for more than a year. (November 20, 1996)
