Oklahoma Town Choked By Mysterious Black Dust
18 May
Summary
- Fine black dust is blanketing Ponca City homes and yards.
- Residents suspect carbon black from a local manufacturer.
- Concerns about health risks and pollution remain unresolved.

Residents in Ponca City, Oklahoma, are grappling with a persistent environmental issue as a fine black dust has begun to blanket their community over the past two years. This mysterious substance coats homes, cars, and yards, raising significant concerns among locals about potential health risks and pollution. Many residents suspect the dust originates from the Continental Carbon Company, a local manufacturer.
Complaints filed with the Oklahoma Department of Environmental Quality over the last two years indicate fugitive dust from Continental Carbon. This isn't the first time the town has experienced such contamination; similar dust events occurred between 1996 and 1999. A federal class-action lawsuit filed in 2005 by the Ponca Tribe of Oklahoma and residents against Continental Carbon highlighted allegations of air-polluting emissions, including sticky carbon black dust that is difficult to remove. The company reached a $10.5 million settlement in 2009.
Officials from the Department of Environmental Quality have not yet confirmed the source of the dust, though monitoring solutions are being actively pursued. Ponca City Mayor Kelsey Wagner stated that investigations are ongoing to identify the origin, emphasizing a science-led approach. Meanwhile, some residents have reported health issues, including cancer diagnoses, which they fear may be linked to past exposure to carbon black, adding urgency to the demand for answers.
