Background

The Reilly Tar & Chemical Corporation Site was used for coal tar distillation and wood preserving from 1917 to 1972. The site was sold to the City of St. Louis Park and converted to recreational and residential use in 1972. Reilly disposed of waste on-site in several ditches that flowed to an adjacent wetland. It is suspected that gases from contaminants related to the former wood-treating operation may be affecting indoor air quality above acceptable long-term risk levels.

The wastes generated by Reilly Tar & Chemical Corporation were mostly polycyclic aromatic hydrocarbons (PAHs), which contaminated the soil and ground water beneath the site. It is estimated that approximately 43,000 people use the ground water from aquifers near the site, which are now treated to meet all required health standards.

Site Updates

September 2013

The EPA has concluded that there is no danger to human health or threats from the vapor intrusion exposure pathway based on the results of a study on various properties on and near the site in June 2013. Where contaminants were detected in indoor air, they were below or within EPA’s acceptable ranges.

EPA and its contractors contacted residents and property owners and obtained access to collect this final round of samples of subslab and background soil gas along with indoor air. EPA recommended this further investigation based on earlier results of its study.

You can view EPA Region 5’s most recent guidance in the EPA's Region 5 Vapor Intrusion Guidebook Exit EPA Disclaimer(October 2010). Visit EPA's Vapor intrusion website to get additional information that includes technical and policy documents.
