The Reilly Tar and Chemical Company site is a 3.66 acre parcel of land situated in Dover, Ohio on Third Street, southeast of the junction of State Route 211 and State Route 39. It is north of Sugar Creek and Tuscarawas River. The site operated from l932 to l956 as a coal tar refinery. The coal tar wastes accumulated on the ground from spillage and other site activities. The site is bordered on the northeast by an abandoned canal turning basin, which functions today as a drainage ditch directing storm water runoff from the city of Dover into the Tuscarawas River. Nearby building consist of commercial property. There is some residential homes north of the site. Also nearby is an undeveloped industrial area south of the site used for fill disposal. The site is inactive and fenced. The aquifer in the deposits is the sole source of drinking water for approximately 30,000 people served by the Dover and New Philadelphia water systems. The site is being addressed through federal, state and potentially responsible party actions.Groundwater and soil are contaminated with petrochemicals from coal tar wastes. Potential health threats include ingesting or direct contact with the contaminated groundwater or soil. Because the site is fenced, exposure to hazardous substances is limited.

A second 5 year review was completed in May 2010. A copy of the plan is located at the Information Repository and a link to the review is on this webpage. The review involved an evaluation of background information, cleanup requirements, effectiveness of the cleanup, maintenance and monitoring efforts. It also looked at ways to operate more efficiently and property reuse.
EPA's cleanup included off-site treatment of highly contaminated sediment and off-site disposal of tarry wastes; on-site disposal of other contaminated soil and sediment in the Ohio-approved cap; hydraulic control and collection of perched water; natural attenuation ; long term monitoring of shallow regional aquifer; and limits on use and access to the sites. The review found the cleanup continues to protect human health and the environment. The next review is in 2015.
Reilly Insustries removed 1,442 tons of coal tar and asphalt materials from the site in l990. Three types of surficial coal tar materials were encourntered during the Expedited Response Action. The response actions included excavation of soils, river seidments, off-site disposal of solidified tarry materials, and excavation of surface water drainage ditch and river sediments. A cap ws placed over the on-site disposed materials, a soil cover over the remainder of the site.
Implementation of the remedy was completed in September 2000. Teery material and construction debris was transported off-site and reclaimed. A 400 foot groundwater recovery trench was installed to capture, treat and dispose of contaminated groundwater in the perched aquifer. After removal of the contaminated soil and installation of the recovery trench, nearly 21000 tons of common burrow fill was brought to the site for grading. The site was reseeded and fenced.
A five year review of the remedy was performed in 2005 and another review completed in 2010. The first five year review indicated that further work was necessary to determine if sediments and surface water posed a threat to fish and animals. As a result of the continuous monitoring and cleanup, it was determined the cleanup continues to protect the human health and the environment.
