Piles of Midwest 'petcoke' raising residents' ire
Susanna Gomez, 37, puts a sock on her 5-year-old daughter, Mariah Burgos, as she talks about living near the the Calumet River and industrial sites on Chicago's Southeast Side where petroleum coke, or petcoke, is stored. Listening to the interview is Gomez's 3-year-old grandson Aerien Pacheco with family friend Eva Nevarez. The grainy black byproduct of oil refining has sparked a new wave of environmental concerns. For Gomez and others in this working-class neighborhood, the issue comes down to one thing: their children’s health.
