COLERAIN, OH (FOX19) - Crews in Colerain say that the pipeline leak has been fixed. However, the damage has been done.
On Monday, officials announced that at least 11 animals are dead as a result to the contamination and 26 others are being cleaned and treated.
Found dead in the nature preserve include eight crayfish, two green frogs and a two-lined salamander. Twenty-six other animals are being cleaned and cared for before being released.
An around-the-clock cleanup continues after more than 20,000 gallons of crude oil spilled into the Oak Glen Nature Preserve in Colerain Township.
The Environmental Protection Agency has said the oil leaked from an underground pipeline traveling nearly a mile through a creek before pooling into a pond.
Philadelphia-based Sunoco Logistics, which according to the Associated Press, largely owns the pipeline, is funding the recovery operations. The company states they have repaired the leak and restarted oil flow on Sunday evening.
According to the Environmental Protection Agency, the oil is contained in all four zones, with 17 thousand gallons already collected.
Officials don't know what caused the pipeline to break. It's a 20-inch line several feet underground.
The Hamilton County Health Department is also doing air quality tests. They say so far, levels are normal but they are encouraging any nearby residents who feel nauseated or light headed due to the strong odor to contact their hotline. That number is 513-946-7808.
