CINCINNATI (AP) -- Dozens of small animals contaminated after oil leaked into an Ohio nature preserve have been cleaned, with some taken to a Dayton science museum for extra care, a parks official said Wednesday.
About 60 salamanders, frogs and crayfish have been collected, the Great Parks of Hamilton County reported. Of those, 21 salamanders have been taken to the Boonshoft Museum, where they will be kept until they are ready for release into the wild.
The museum is some 60 miles from the Oak Glen Nature Preserve west of Cincinnati, where federal officials estimated more than 20,000 gallons leaked from a pipeline. Sunoco Logistics reported the leak in its Texas-to-Michigan pipeline early March 18, triggering emergency responses by the company, federal and state environmental protection agencies, and wildlife teams and local authorities.
No impact on local water and air quality has been detected, and large animals don't appear to have been affected. Authorities say they will be long-term monitoring of the 374-acre preserve.
So far, 28 small animals have been found dead in the preserve or died soon after being taken in, Great Parks spokeswoman Jennifer Sivak said.
A fence was put up earlier around a contaminated stream to keep animals out.
Crews dug trenches and set absorbent barriers backed by straw bales to prevent oil-saturated soil from spreading. They are removing oil sheen lingering on stream banks and rocks from the leak, and have stepped up efforts to prevent any spread by rainfall this week.
The pipeline has been repaired and reopened. The cause of a pipeline crack that led to the leak has been under investigation.
