Hazardous Waste Cleanup: Worthington Steel Company in Malvern, Pennsylvania

On this page:

In October 3, 2002, EPA determined that the Human Health Exposures Under Control and the Migration of Contaminated Groundwater Environmental Indicators had been met.

Cleanup Background

In June 2002, the Worthington Steel (Facility) shut down all operations and sold the property to O’Neil Properties who is currently redeveloping the property into commercial offices and retail stores.   The primary contaminant in groundwater at the facility is the cyanide and localized volatile organic compounds (VOCs) plumes, which are contained within the site property lines.  O’Neil Properties is addressing the groundwater and soil contamination under the Pennsylvania Land Recycling and Environmental Remediation Standards Act (Act 2).  The cyanide plume has been defined and stabilized onsite.  Localized VOCs groundwater plumes are within the property boundary lines.  Ongoing groundwater monitoring will ensure that the cyanide and localized VOCs plumes are stabilized onsite.

EPA supports the actions, which the Pennsylvania Department of Environmental Protection Agency (PADEP) has taken and those it proposes to take to address environmental conditions at the Facility.  Based on currently known information and site conditions, EPA neither plans nor anticipates taking any further corrective actions at the Facility.  EPA relies upon PADEP to resolve any current or future closure and corrective action issues associated with the Facility.  The investigation and remediation proceeded under the PADEP Act 2 Program.  In 2006, PADEP approved the “Final Report for the Former Worthington Steel Facility” that asserts that the investigation and remediation met the Act 2 Standard within the site specified.   Areas that have yet to be developed will proceed in accordance with the Post Remediation Care Plan Addendum to the Final Report when the proposed redevelopment of these areas are realized.
