Creosote contamination in the Little Scioto River was most likely caused by poor disposal practices at the former Baker Wood Creosoting facility located nearby.

After EPA cleaned up the Baker Wood property, workers drained and dredged a 1 1/4-mile stretch of river. The area was backfilled with clean soil. Contaminated sediment was removed and dried on a pad just east of the cleanup area. It was eventually shipped to Bucyrus, Ohio for proper disposal.

During the most recent phase, about ¾ mile of river was cleaned up. Work ended near the intersection of State Route 95 in November 2006. It was funded by EPA ($2 million) and Ohio EPA ($1 million). Additional funding to complete the cleanup along the river to State Route 739 was no longer available.

The project was originally started in 2002 and paid for by U.S. Coast Guard Oil Pollution Act funds. About ½ mile of North Rockswale Ditch and ½ mile of the river was dredged at that time. When that portion of the cleanup was complete, USCG and EPA agreed that Superfund money was a more appropriate way to pay for the rest of the cleanup.

Technical Assistance Grant (TAG) and Community Advisory Group (CAG) are two ways the community can get involved. Learn more about CAGs and TAGs

Site Updates


June 2014

Results from surface water and sediment (mud) samples taken from the Little Scioto River and its tributaries were included in a document called a remedial investigation report which was completed in August 2013. Those results confirmed that compounds called polycyclic aromatic hydrocarbons, or PAHs, from the former Baker Wood Creosoting site on Holland Road are still present. Based on the information in that report, another document called a feasibility study will be completed this winter.  It will list several possible cleanup options for the river and Baker Wood, if necessary. Next summer, we expect to present a recommended cleanup plan that will be available for public review and comment.

Sampling started at Green Camp and moved north past state Route 309. EPA contractors tested for PAHs which are associated with coal tar creosote used to preserve wood while the plant operated from the 1890s to the 1960s. We also tested for metals (in water and sediment) that may have come from Baker Wood when it was used as a metal scrap yard in the 1960s and 70s.

Fish and mussels were also sampled to determine if there are any ecological risks. Contaminants including PAHs and metals were found in the mussel and fish samples.  Results are detailed in the risk assessment which is part of the remedial investigation report.

EPA also returned to the Baker Wood property to update information first obtained in 2002. Soil and groundwater samples were taken again and were analyzed by an EPA-approved lab. Results show that further cleanup may be needed because contaminated soil, groundwater and source material remains on-site.  Although EPA addressed the immediate threats in its previous cleanup, we needed to collect more information to determine the extent of contamination and its effect on the river through its tributary, North Rockswale Ditch.
