Hazardous Waste Cleanup: Univar USA Incorporated (Formerly: Vopak USA Incorporated) in Coraopolis, Pennsylvania

On this page:


Cleanup Status

In September 2012, the United States Environmental Protection Agency (EPA) selected Engineering and Institutional Controls (ICs) as the Final Remedy to remediate groundwater and soil contamination at the Univar USA facility located in Coraopolis, Pennsylvania (the Facility).  Components of the engineering controls consist of the operation and maintenance of the existing groundwater monitoring and recovery wells as long as the contamination levels in groundwater are above drinking water standards.   Furthermore, the Facility will continue to implement the soil vapor extraction system until soil sampling demonstrates that the Pennsylvania Non-Residential SHSs for subsurface soils are attained. 

Because contaminant concentrations remain above levels appropriate for residential uses, EPA is requiring ICs to prohibit on-site groundwater use and restrict the Facility property to non-residential uses.  The ICs will require that all subsequent owners comply with these restrictions.  ICs are non-engineered instruments such as administrative and/or legal controls that minimize the potential for human exposure to contamination and/or protect the integrity of the remedy by limiting land or resource use.  The ICs may be implemented through a permit, order, or in the form of an environmental covenant pursuant to the Pennsylvania Uniform Environmental Covenants Act (UECA-Act 68) and to be recorded with the deed for the Facility property. 

On June 21, 1999, EPA determined that both the Human Exposures and Groundwater Environmental Indicators have been met.  There is no contamination problem that creates an unacceptable risk to human health and the migration of groundwater contamination is under control.

The Facility is approximately three acres in size and is located at 6000 Casteel Drive, Coraopolis, Pennsylvania.  In 1964, McKesson Chemical Company (McKesson) began operating a solvent distribution service center at the Facility.   McKesson stored chemical products in 10 above-ground storage tanks (ASTs).   In 1989, Van Waters and Rogers Inc. (VWR) purchased the Facility.  During its ownership of the Facility, VWR decommissioned some of the ASTs. In 2002, Univar purchased the Facility and closed the solvent distribution service operation.  The 10 ASTs were decommissioned and removed as part of Facility closure activities.  Currently, the only significant structure at the Facility is a warehouse that is leased to a moving company, Fdl Logistics.  Univar continues to be owner of the Facility.
