Residents of Ponca City, Oklahoma, are reporting a mysterious black dust coating their homes and schools. Many locals believe the substance is carbon black, a powder used in tire manufacturing, allegedly leaking from the Continental Carbon Company plant. This incident follows a history of environmental disputes, including a 2009 settlement where the company paid 10.5 million dollars over air pollution claims. Local officials and the Department of Environmental Quality are currently monitoring the area to confirm the source of the particulates.
