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, and maintenance and monitoring of the operating remedy. The review also looked at ways to operate the remedy more efficiently and the possibility of re-using the Site property.
EPA's cleanup included: off-site treatment of highly contaminated sediment and off-site disposal of tarry wastes; on-site containment of other contaminated soil and sediment under a constructed cap that meets Ohio EPA's standards; hydraulic control and collection of perched groundwater; natural attenuation ; long term monitoring of the shallow regional aquifer; and limits on use and access to the sites. The 2010 review found the cleanup continues to protect human health and the environment. The next review will be completed in 2015.
Reilly Industries removed 1,442 tons of coal tar and asphalt materials from the site in l990. Three types of surficial coal tar materials were encountered during the Expedited Response Action. The response actions included: excavation of soils, excavation of river sediments, off-site disposal of solidified tarry materials, and excavation of surface water drainage ditch sediments. A cap was placed over the materials disposed of on site, and a soil cover was installed over the remainder of the site.
The remedy was completed in September 2000. Tarry material and construction debris were transported off-site and reclaimed. A 400 foot groundwater recovery trench was installed to capture contaminated groundwater in the perched aquifer for treatment and disposal. After removal of the contaminated soil and installation of the recovery trench, nearly 21,000 tons of common burrow fill was brought to the site, which was graded. reseeded, and fenced.
Five year reviews of the remedy were performed in 2005 and 2010. The 2005 five year review indicated that further work was necessary to determine if sediments and surface water posed a threat to fish and animals. Based on site monitoring and cleanup information, it was determined the remedy that is currently operating continues to protect the human health and the environment.
